+<p>The <code>icd-db</code> program can be used to validate and ingest model files into the database. In order to use the <code>icd-db</code> program, the MongoDB server must be running (see <a href="../installing/installing.html#installing-mongodb">Installing MongoDB</a>). Most of what <code>icd-db</code> command provides can also be done using the web interface, so it’s possible to skip this step.</p>
+<p><img src="../images/icd-db/icd-db.png" /></p>
+<p>The figure above shows the usage of the <code>icd-db</code> program. Its primary purpose is to validate and ingest model files into the ICD Model File Database. If any of the model files under the given directory don’t pass validation, then nothing is changed in the database. Error messages indicate where the validation errors occurred, including a file name and a position in JSONPath format.</p>
+<p>Below you see the options for the <code>icd-db</code> command, which are listed with the &ndash;help option. Some of the options are basic querying of the database, to see what subsystems and components are currently in the local database, and information about them, such as data rates and units used. This can be useful when developing and browsing APIs without bringing up the full system.</p>
+<pre><code>icd-db 3.0.0
+Usage: icd-db [options]
+
+  --db &lt;name&gt;              The name of the database to use (default: icds4)
+  -h, --host &lt;hostname&gt;    The host name where the database is running (default: localhost)

+ 			   suffix (&#39;scala&#39;, &#39;java&#39;, &#39;ts&#39; (typescript), py (python))
+  --drop [db|subsystem|component]
+                           Drops the specified component, subsystem, or the entire icd database

+</code></pre>
+<p>Some example commands are shown below.</p>
+<p>To ingest the directory of model files created in the last section use the <code>-i</code> or <code>--ingest</code> option:</p>
+<pre><code>icd-db --ingest directoryName
+</code></pre>
+<p>The <code>–l</code> or <code>--list</code> option with a value of <code>subsystems</code>, <code>assemblies</code>, <code>HCDs</code>, or <code>all</code> will list the components in the database that meet the criteria:</p>
+<pre><code>$ icd-db –list all
+</code></pre>
+<p>To list just assemblies:</p>
+<pre><code>$ icd-db –list assemblies
+</code></pre>
+<p>List only HCDs:</p>
+<pre><code>$ icd-db –list hcds
+</code></pre>
+<p>List the existing subsystems in the local database:</p>
+<pre><code>$ icd-db –list subsystems
+</code></pre>
+<p>Several other commands are available and are not documented here.</p>
+<h2><a href="#generating-documents-and-code-from-the-icd-database" name="generating-documents-and-code-from-the-icd-database" class="anchor"><span class="anchor-link"></span></a>Generating Documents and Code from the ICD Database</h2>
+<p>The <code>icd-db –o</code> option can be used to output a file in a format based on the file’s suffix (<code>.pdf</code> and <code>.html</code> are supported for generating documentation and <code>.scala</code>, <code>.java</code>, <code>.py</code> (python) and <code>.ts</code> (typescript) are supported for generating code containing the event, command and parameter keys for the given subsystem and/or component:</p>
+<pre><code>$ icd-db –s TCS -o TcsApi.pdf    // Generate a PDF for TCS
+$ icd-db –s TCS -o TcsApi.scala  // Generate Scala code for TCS
+$ icd-db –s TCS -o TcsApi.java   // Generate Java code for TCS
+$ icd-db –s TCS -o TcsApi.py     // Generate Python code for TCS
+$ icd-db –s TCS -o TcsApi.ts     // Generate Typescript code for TCS
+</code></pre>
+<p>You can also generate documentation and code for a specific component of a subsystem and specify the package name (required for Java):</p>
+<pre><code>$ icd-db –s IRIS -c ifs.scale -o IrisApi.pdf                     // Generate a PDF for IRIS.ifs.scale
+$ icd-db –s IRIS -c ifs.scale –package iris.api -o IrisApi.scala // Generate Scala code for IRIS.ifs.scale
+$ icd-db –s IRIS -c ifs.scale –package iris.api -o IrisApi.java  // Generate Java code for IRIS.ifs.scale
+$ icd-db –s IRIS -c ifs.scale -o IrisApi.py                      // Generate Python code for IRIS.ifs.scale
+$ icd-db –s IRIS -c ifs.scale -o IrisApi.ts                      // Generate Typescript code for IRIS.ifs.scale
+</code></pre>
+<p>The generated code always contains a top level object (scala), class (java, python) or namespace (typescript) with the base name of the file. Then there are nested objects for each component, and in each component, nested objects for each event and command, containing constants for all the event keys, command names and parameter keys.</p><div class="callout note "><div class="callout-title">Note</div>
+<p>After generating the code, <code>icd-db</code> attempts to format it using a command line formatter application in your shell path. It uses <a href="https://scalameta.org/scalafmt/">scalafmt</a> for Scala, <a href="https://prettier.io/">prettier</a> for TypeScript, <a href="https://github.com/psf/black">black</a> for Python and <a href="https://github.com/google/google-java-format">google-java-format</a> for Java. If it doesn&rsquo;t find those it will print a message, but still generate the file. You can install scalafmt and <code>google-java-format</code> with <a href="https://get-coursier.io/">cs (coursier)</a>, <code>black</code> with <code>pip</code> (<code>pip3</code>), and <code>prettier</code> with <a href="https://www.npmjs.com/">npm</a>.</p></div>
+<p>You can also generate code using the web interface, as described later.</p>

+<p>FITS keyword data is stored in three files under <a href="https://github.com/tmt-icd/DMS-Model-Files/tree/master/FITS-Dictionary">DMS-Model-Files</a> on GitHub. Once DMS is published, the file should be automatically loaded by the <code>icdwebserver</code> or <code>icd-git --ingest</code> commands. Until then, the FITS keywords, channels and tags can be manually loaded into the icd database once by running (from the icd source directory):</p>
+<pre><code>icd-fits -i examples/3.0/FITS-Dictionary.json --ingestChannels examples/3.0/FITS-Channels.conf --ingestTags examples/3.0/FITS-Tags.conf
+</code></pre>
+<p>Alternatively you can check out and manually ingest DMS-Model-Files into the local icd database by using the Upload feature in the icd web app or with the command line:</p>
+<pre><code>icd-db -i DMS-Model-Files
+</code></pre>
+<p>The contents of the files are as follows: * * <code>FITS-Dictionary.json</code> - This is the FITS dictionary and contains an entry for each FITS keyword, mapping it to source event parameters. If a keyword has multiple sources, named channels are used, each containing one source. * <code>FITS-Channels.conf</code> - This defines which channels are available for each subsystem (Channels are used when a FITS keyword has multiple source event parameters). * <code>FITS-Tags.conf</code> - Assigns tags to FITS keywords, which can be used in the web app to filter and display the FITS keyword information.</p>
+<p>Besides the three above files, FITS keyword information can be defined in the <code>publish-model.conf</code> files for each subsystem component. Event parameters can define the associated keyword as follows:</p>
+<pre><code>keyword = IMGDISWV
+</code></pre>
+<p>If the keyword has multiple source parameters, you can specify the channel:</p>
+<pre><code>keyword = IMGDISWV
+channel = ATM
+</code></pre>
+<p>In some more complicated cases, you can also specify multiple keywords whose values are taken from an index (or rowIndex for matrix/2d arrays) in the parameter&rsquo;s array values:</p>
+<pre><code>keywords: [
+     {
+       keyword = OIWFS1PS
+       rowIndex = 0
+     }
+     {
+       keyword = OIWFS2PS
+       rowIndex = 1
+     }
+     {
+       keyword = OIWFS3PS
+       rowIndex = 2
+     }
+]
+</code></pre>
+<p>The FITS keyword definitions in a subsystem&rsquo;s model files can be used to generate a new FITS dictionary by merging the existing FITS dictionary with the definitions in the publish model files. In this case the information from the published events overrides the information in the existing FITS dictionary:</p>
+<pre><code>icd-fits --subsystem IRIS --generate FITS-Dictionary.json
+</code></pre>
+<p>Or using the short form options and with a subsystem version:</p>
+<pre><code>icd-fits -s IRIS:1.7 -g FITS-Dictionary.json
+</code></pre>
+<p>The generated FITS dictionary JSON file can then be copied to the <a href="https://github.com/tmt-icd/DMS-Model-Files/tree/master/FITS-Dictionary">DMS-Model-Files</a> repository and published, so that it will be automatically used by the icd web app and command line apps (Note that Publishing DMS-Model-files requires special permission).</p>
+<p>You can also manually load the new FITS dictionary into your local icd database using the command line:</p>
+<pre><code>icd-fits -i FITS-Dictionary.json
+</code></pre>
+<h2><a href="#generating-a-document-listing-the-fits-keywords" name="generating-a-document-listing-the-fits-keywords" class="anchor"><span class="anchor-link"></span></a>Generating a Document listing the FITS Keywords</h2>
+<p>You can use <code>icd-fits</code> to print a list of keywords coming from a subsystem or component to stdout. For example, the following command lists the keywords for IRIS:</p>
+<pre><code>icd-fits --subsystem IRIS --list
+</code></pre>
+<p>Or you can use the short form options and restrict the output to a component:</p>
+<pre><code>icd-fits -s IRIS -c pupilview -l
+</code></pre>
+<p>You can create a PDF of the IRIS FITS keywords like this:</p>
+<pre><code>icd-fits -s IRIS -o IRIS-Keywords.pdf
+</code></pre>
+<p>The format of the output file depends on the suffix. You can also generate <code>csv</code>, <code>html</code>, <code>json</code> and <code>conf</code> (HCON) formatted files with the same information.</p>

+<h1><a href="#introduction" name="introduction" class="anchor"><span class="anchor-link"></span></a>Introduction</h1>
+<p>The Interface Database System (IDBS) was created to help component builders and system engineering understand the programming interfaces of software components created with the TIO Common Software.</p>
+<h2><a href="#background" name="background" class="anchor"><span class="anchor-link"></span></a>Background</h2>
+<p>The project was started for the following purposes:</p>
+<ol>
+  <li>To document the interfaces of components based on TIO Common Software in the TIO Software System.</li>
+  <li>To support a more agile development process by tracking changes to component interfaces over the course of TMT construction.</li>
+  <li>To understand how events are used in the software system.</li>
+  <li>To support the Systems Engineering change control process by understanding how planned interface changes influence the software system.</li>
+  <li>To understand the software interfaces between subsystems and components in the software system.</li>
+  <li>To decrease the workload of developers by generating API and ICD documentation that can be used for reviews.</li>
+  <li>Provide a platform for understanding and modeling the interactions of components during observing. This might include adding additional information to the models.</li>
+</ol>
+<h2><a href="#design-background" name="design-background" class="anchor"><span class="anchor-link"></span></a>Design Background</h2>
+<p>There might be several ways to solve the problems IDBS is addressing. One approach might be to use/extend a source code documentation markup tool such as Doxygen or the 15+ other products a Google search on software documentation shows. The reason this approach wasn’t taken is that the problem is not about documenting source code, it is modeling components and interfaces and delivering a database that provides a basis for understanding and tracking interfaces and their changes. The models need to drive the source, not the other way around. Documentation tools can generate documents but extracting information and putting it into a database is not the scope of these tools. The primary need is to have a database of interfaces and delivering interface documentation is a second, although important, side effect. Ultimately, it is a question of how to best describe a component and its interfaces.</p>

+<h1><a href="#overview" name="overview" class="anchor"><span class="anchor-link"></span></a>Overview</h1>
+<p>The IDBS software currently consists of the following programs: </p>
+<ul>
+  <li>icd-db</li>
+  <li>icd-git</li>
+  <li>icd-viz</li>
+  <li>icd-fits</li>
+  <li>icdwebserver</li>
+</ul>
+<p>The components of the Interface Database System are shown below. They are briefly described here, with more details provided in subsequent sections.</p>
+<p>The workflow proceeds from left to right.</p>
+<p><img src="../images/overview/fig1.jpg" /></p>
+<p>The TIO developer, using Common Software for his/her components, creates component model files. These files are validated and ingested into the ICD Model File Database using either the <code>icd-db</code> command or a web application called <code>icdwebserver</code>. These were developed to work with the ICD Model File Database and provide the functionality the users of the system need. The model files are stored and published in Git repositories on GitHub. The <code>icd-git</code> application can be used to sync the local database with the published versions on GitHub. The icd web app also gets its information from the published versions on GitHub, in addition to any unpublished versions that a developer is working with locally. The <code>icd-viz</code> command line application can be used to generate a graph of component or subsystem relationships. This feature requires that <a href="https://graphviz.org/">graphviz</a> is installed and is also available in the icd web app. The <code>icd-fits</code> command can be used to view information about FITS keywords and their source events.</p>
+<h2><a href="#icd-db" name="icd-db" class="anchor"><span class="anchor-link"></span></a>icd-db</h2>
+<p>The <code>icd-db</code> program exists to validate and ingest model files into a local ICD Model File Database. When creating or modifying the models, this feature can be used to incorporate working versions of the files into the database system. The <code>icd-db</code> program also allows some informative queries to be performed directly on the database, showing what subsystem and components exist in the database, and information about them such as data rates, data types, and units used. Note that these operations only work on the models that exist in the local version of the database, and do not access the released models on the GitHub repository.</p>
+<h2><a href="#icdwebserver" name="icdwebserver" class="anchor"><span class="anchor-link"></span></a>icdwebserver</h2>
+<p>The <code>icdwebserver</code> web application provides the IDBS user application interface. The browser-based user interface allows the ingesting of model files, publishing them, and displaying versioned APIs for each component. An API is defined as all the functionality of a component or subsystem including inputs and outputs. An ICD is produced by taking the intersection of two subsystem API documents.</p>
+<p>The IDBS browser provides the ability to browse the APIs for both published and unpublished models. The published APIs are constructed from models obtained from the git repository which stores the released versions, and the unpublished APIs are constructed by accessing the models stored in the local database that have been ingested using the icd-db program or the web app.</p>
+<p>The current version of the IDBS browser user interface includes the following features:</p>
+<ul>
+  <li>Allows browsing all the subsystems and their components (including previously published versions as well as unpublished working versions).</li>
+  <li>View the API for a subsystem or an individual component.</li>
+  <li>Browse interfaces between subsystems, or components within subsystems.</li>
+  <li>Upload directories containing the model files for a subsystem API</li>
+  <li>Publish APIs and ICDs (if enabled, for TIO SE use only)</li>
+  <li>Print ICD or API information from the browser (using browser print).</li>
+  <li>Export an API or ICD as a PDF document.</li>
+  <li>Show the publish history of an API or ICD and compare the differences between versions</li>
+  <li>Generate a PDF document that shows the amount of storage required for all archived events</li>
+  <li>Generate a graph of component or subsystem relationships</li>
+</ul>
+<p>A public (password-protected) ICD web service has been set up that allows users to view the APIs and ICDs of all TIO subsystems and components. The uploading functionality of this web service has been disabled; new model files must be committed to the GitHub repository to add new versions to this system, which are automatically added to the web service whenever the system is refreshed. Log-in credentials can be obtained from Systems Engineering. This web service is located at: <a href="https://sdb.tmt.org/">https://sdb.tmt.org/</a>.</p>
+<h2><a href="#icd-git" name="icd-git" class="anchor"><span class="anchor-link"></span></a>icd-git</h2>
+<p>The icd-git application is a command line tool that can be used to update your local icd database with the published versions from GitHub (Use: <code>icd-git --ingest</code>). Otherwise, this application is primarily meant to be used by systems engineering to manage official releases of APIs and ICDs by interacting directly with versions of subsystem model files as maintained by the official GitHub repository (<a href="http://github.com/tmt-icd)">http://github.com/tmt-icd)</a>. Since this tool is mainly intended to be used by the Systems Engineering group, it is not documented here.</p>
+<p>It is also possible to publish APIs and ICDs using the web app (<code>icdwebserver</code>) and this is now the preferred way to do it. The API publishing features of the web app are protected by password and only enabled for use by those with permission to push to the GitHub repository that holds that information.</p>
+<h2><a href="#icd-viz" name="icd-viz" class="anchor"><span class="anchor-link"></span></a>icd-viz</h2>
+<p>The <code>icd-viz</code> command line application generates a graph of the relationships of given components or subsystems. There are a number of options for controlling what is displayed and the format of the image produced. </p>
+<p>This application relies on <a href="https://graphviz.org/">graphviz</a> to generate the graph from a description generated in the <a href="https://graphviz.org/doc/info/lang.html">dot</a> graph description language. Run <code>icd-viz –help</code> to see the command line options (These are also listed in the <a href="https://github.com/tmtsoftware/icd/blob/master/icd-viz/README.md">README.md</a> file for the <code>icd-viz</code> subproject on GitHub). Note that the icd web app also provides a user interface for most of these features. See <a href="../webapp/webapp.html">Using the Web Interface</a> for more information on that. </p>
+<p>The icd-viz command lets you specify one or more TIO components or subsystems (in which case all components in the subsystem are used). These are the primary nodes of the graph, drawn as solid ovals. Then, all of the components that publish events for these components or subscribe to events from these components are added to the graph (as dashed ovals). The graph edges indicate the flow of events and commands between the components and optionally show any errors, such as events subscribed from publishers that do not exist, or published events with no subscribers.</p>
+<p>The default colors used for the graph can be found in <a href="https://github.com/tmtsoftware/icd/blob/master/icd-viz/src/main/resources/reference.conf">icd/icd-viz/src/main/resources/reference.conf</a> and can also be overridden with a command line option like <code>-Dicd.viz.color.IRIS=darkgreen</code> (replace IRIS with the subsystem). The colors should be valid Graphviz colors.</p><div class="callout note "><div class="callout-title">Note</div>
+<p>The design of the icd-viz application is based on previous work (<a href="https://github.com/tmtsoftware/NIC/blob/master/script/icdRelationships.py">NIC/scripts/icdRelationships.py</a>) from Ed Chapin of the NRC.</p></div>
+<p>Example icd-viz command line usage:</p>
+<p>Plot all interfaces for a particular component to the screen, label events and commands, and show missing events and commands:</p>
+<pre><code>icd-viz --components iris.oiwfs.poa --missingcommands true --missingevents true --commandlabels true --eventlabels true
+</code></pre>
+<p>Below is the resulting image from the above command:</p>
+<p><img src="../images/overview/icd-viz.png" /></p>
+<h2><a href="#icd-fits" name="icd-fits" class="anchor"><span class="anchor-link"></span></a>icd-fits</h2>
+<p>The icd-fits command line application can be used to manually ingest FITS dictionary files into the icd database and produce tables in PDF and other format containing information about all the FITS keywords and the subsystem events that are the source of the keyword values. There are command line options that allow you to filter the list of keywords by source subsystem and component as well as by tag. </p>
+<p>The command can also be used to merge the FITS keyword definitions found in the publish model files with the current FITS dictionary stored in the icd database to produce a new FITS dictionary, where the keyword definitions in the publish model files override the ones previously in the FITS dictionary. This can be used to update the <code>FITS-Dictionary.json</code> file in the <a href="https://github.com/tmt-icd/">tmt-icd</a> <a href="https://github.com/tmt-icd/DMS-Model-Files">DMS-Model-Files</a> GitHub repository, which is loaded automatically whenever the DMS model files are ingested into the icd database.</p>
+<p>The main source for the FITS dictionary files is in the <code>FITS-Dictionary</code> directory in the tmt-icd <a href="https://github.com/tmt-icd/DMS-Model-Files">DMS-Model-Files</a> GitHub repository. One file there, <code>FITS-Dictionary.json</code>, lists information about the FITS keywords and related subsystem, component, event, and parameter. Another file, <code>FITS-Channels.conf</code>, lists the available channel names for FITS keywords that have multiple source events or parameters. The third file, <code>FITS-Tags.conf</code>, assigns tags to the keywords, such as <code>SL</code> (Seeing-Limited), <code>DL</code> (Diffraction-Limited), or the <code>WFOS</code>, <code>IRIS</code> or <code>MODHIS</code> instruments.</p>
+<p>Some keywords can come from multiple sources or channels, such as imaging or IFS. This information is also included in the FITS Dictionary JSON file above. When you specify the FITS keyword in an event’s parameter description in <code>publish-model.conf</code>, in most cases it is enough to just list the keyword name with keyword = keyname. If the same FITS keyword has multiple different source events/parameters, it needs to be assigned a channel as well. For example: <code>channel = IFS</code>. The channel name needs to be one of the predefined names for that subsystem listed in <a href="https://github.com/tmt-icd/DMS-Model-Files/blob/master/FITS-Dictionary/FITS-Channels.conf">FITS-Channels.conf</a>.</p>

+<p><em>Note that at the time of writing these files are still in development and may contain incorrect information.</em></p>
+<h2><a href="#implementation-details" name="implementation-details" class="anchor"><span class="anchor-link"></span></a>Implementation Details</h2>
+<p>The IDBS is implemented in Scala, a JVM-based language (<a href="http://www.scala-lang.org)">http://www.scala-lang.org)</a>. The web application is developed using Play (<a href="https://www.playframework.com)">https://www.playframework.com)</a>. These are tools selected for OSW and CSW. The ICD information is stored in a document database called MongoDB (<a href="https://www.mongodb.org)">https://www.mongodb.org)</a>.</p>

+<h1><a href="#installing-idbs" name="installing-idbs" class="anchor"><span class="anchor-link"></span></a>Installing IDBS</h1>
+<p>While the public ICD web service can be useful for browsing existing APIs, it can be easier to develop model files by using the IDBS system locally. The icd-db and icdwebserver programs are useful for the developer in order to validate and ingest model files into the local ICD database. The ICD software can be installed on any machine with a Java JDK version of 17 or greater. The details of installing Java on a system are not covered here (Java 17 was used for testing).</p>
+<p>The following external applications are also required at runtime: * <a href="https://graphviz.org/">graphviz</a> – The <code>dot</code> command is required to generate graphs and for inline UML support. * <a href="https://swagger.io/docs/open-source-tools/swagger-codegen/">swagger-codegen</a> – Required for documenting HTTP services (at least version 3.0.36, install with <code>cs install --contrib swagger-codegen</code>) * <a href="https://www.mongodb.com/docs/manual/core/transactions/">mongodb</a> – Required for the database that stores the API information (see below) * <a href="https://jsonnet.org/">jsonnet</a> - Required to process model files written in the <code>jsonnet</code> language</p>
+<p>The following applications are optional and used if present to fomat generated source code: * <a href="https://scalameta.org/scalafmt/docs/installation.html">scalafmt</a> - Used to format generated Scala source files (Install with <code>cs install scalafmt</code>) * <a href="https://github.com/google/google-java-format">google-java-format</a> - Used to format generated Java source files * <a href="https://github.com/psf/black">black</a> - Used to format generated Python source files * <a href="https://prettier.io/">prettier</a> - Used to format generated Typescript source files</p>
+<h2><a href="#installing-the-binary-release" name="installing-the-binary-release" class="anchor"><span class="anchor-link"></span></a>Installing the Binary Release</h2>
+<p>Binary releases of IDBS are available on GitHub at:</p>
+<p><a href="https://github.com/tmtsoftware/icd/releases">https://github.com/tmtsoftware/icd/releases</a></p>
+<p>Please download the most recent release. The file is available as a zip file. It can be unpacked on Mac or Linux with:</p>
+<pre><code>unzip idbs-$version.zip
+</code></pre>
+<p>where <em>$version</em> is the release version.</p>
+<p>Once the installation is unpacked it creates a directory named <code>idbs-$version</code> that contains three subdirectories: <code>bin</code>, <code>conf</code>, and <code>lib</code>. Inside <code>bin</code> are the application scripts: <code>icd-db</code>, <code>icd-git</code>, <code>icd-viz</code>, <code>icd-fits</code> and `icdwebserver.</p>
+<p>The image below shows the basic directory structure of the IDBS binary distribution downloaded from GitHub:</p>
+<p><img src="../images/installing/fig2.jpg" /></p>
+<p>The <code>icd-db</code> or <code>icdwebserver</code> program is needed to validate and ingest the directories containing your model files. You might want to put the <code>idbs-$version/bin</code> directory in your shell path.</p>
+<h2><a href="#installing-the-source-release" name="installing-the-source-release" class="anchor"><span class="anchor-link"></span></a>Installing the Source Release</h2>
+<p>The source for the IDBS programs can be downloaded from the tmtsoftware GitHub repository with the command:</p>
+<pre><code>git clone https://github.com/tmtsoftware/icd.git
+</code></pre>
+<p>The git clone command will result in a local directly called icd. An <code>install.sh</code> script is provided that builds and installs all the subprojects into a directory called <code>install_icd</code> in the parent directory of the download directory (the <code>../install_icd</code> directory). The <code>install_icd</code> directory contains the directories: <code>bin</code>, <code>conf</code>, and <code>lib</code>. Inside the <code>bin</code> directory are <code>Linux/Mac</code> friendly scripts to start the components of IDBS.</p>
+<p>The code is built with the <code>sbt</code> build program, which must be downloaded and installed (see <a href="http://www.scala-sbt.org)">http://www.scala-sbt.org)</a>. That task is not covered here. The “All Platforms” or “Manual installation” is quick, which is the suggested approach.</p>
+<p>The <code>icdwebserver</code> application starts the web application (by default on localhost:9000).</p>
+<h2><a href="#installing-mongodb" name="installing-mongodb" class="anchor"><span class="anchor-link"></span></a>Installing MongoDB</h2>
+<p>In order to run the icd applications locally, it is necessary to install the database MongoDB, which is available at <a href="https://www.mongodb.org">https://www.mongodb.org</a>. The community edition is sufficient for our needs and instructions for installation can be found for a variety of platforms at</p>
+<p><a href="https://docs.mongodb.com/manual/administration/install-community/">https://docs.mongodb.com/manual/administration/install-community/</a>.</p>
+<p>Note that it may be necessary to adjust system limits in order for mongod to run correctly. See</p>
+<p><a href="https://docs.mongodb.com/manual/reference/ulimit/">https://docs.mongodb.com/manual/reference/ulimit/</a>.</p>
+<p>Note: If you wish to “start over” with no database entries, you can use the command <code>icd-db –drop db</code>. Run <code>icd-git –ingest</code> to get the published APIs and ICDs from the released versions on GitHub.</p>

+<p>In the OMOA, subsystem software consists of components: Hardware Control Daemons, Assemblies, Sequencers, and Applications. Model files that provide information about the component and its interfaces are created for each of the components. This section describes the model files. The model files are named: component-model, command-model, publish-model, alarm-model, and subscribe-model. In addition, each subsystem has a single subsystem-model file and may have one or more <code>$subsystem-icd-model</code> files that contain additional information about the interface between two subsystems. Separate files were created (rather than one larger file) in order to keep the configuration files simpler and easier to type.</p>
+<p>The following table shows the different types of model files and what they describe:</p>

+<p>The component is only required to create a <code>command-model.conf</code>, <code>publish-model.conf</code>, <code>alarm-model.conf</code>, or <code>subscribe-model.conf</code> if it provides or uses the features described in the model files (i.e. if the component does not subscribe to events, then a <code>subscribe-model.conf</code> file is not needed).</p>
+<p>Model files are text files written in a superset of JSON called <a href="https://github.com/typesafehub/config/blob/master/HOCON.md">HOCON</a>, which provides syntactic sugar for writing JSON, but can be exported as pure JSON. In addition, most fields support GitHub style MarkDown as well as HTML tags. LaTeX math markup and UML are also supported (see below). In addition, it is possible to reuse certain repetitive definitions, such as those for events, commands and parameters by using the <code>ref</code> keyword in the model files to refer to another definition. The syntax is described below. Each type of model file has a schema which specifies the allowed structure of the contents within, including specifying the optional and required items, item types, allowed ranges, etc. The following sections describe each of the model files including necessary fields.</p>

+<h2><a href="#inner-document-links" name="inner-document-links" class="anchor"><span class="anchor-link"></span></a>Inner-Document Links</h2>
+<p>It is possible to make inner-document links to existing anchors using Markdown syntax. The easiest way to see the syntax for the ids is to look at the generated HTML. For example, the output of:</p>
+<pre><code>icd-db -s NFIRAOS -o NFIRAOS.html
+</code></pre>
+<p>Note that the name attribute is used in the generated HTML instead of id, since the PDF generator required that. Many of the anchors have the following syntax:</p>
+<p><em>&lt;thisComponent-&gt;action-&lt;itemType-&gt;subsystem.&lt;component.&gt;name</em></p>
+<p>where</p>
+<ul>
+  <li><em>$thisComponent</em> is the component being described</li>
+  <li><em>$action</em> is one of {publishes, subscribes, sends, receives}</li>
+  <li><em>$itemType</em> is one of {Event, ObserveEvent, Alarm, Command}</li>
+  <li><em>$subsystem</em> is the subsystem for the item</li>
+  <li><em>$component</em> is the component for the item</li>
+  <li><em>$name</em> is the name of the item being published, subscribed to, or the command being sent or received</li>
+</ul>
+<p>For example, to link to the description of a published event named <code>heartbeat</code> in the lgsWfs component in the TEST subsystem:</p>
+<pre><code>See: [here](#lgsWfs-publishes-Event-TEST.lgsWfs.heartbeat). 
+</code></pre>
+<h2><a href="#reusing-definitions-for-events-commands-parameters-refs-" name="reusing-definitions-for-events-commands-parameters-refs-" class="anchor"><span class="anchor-link"></span></a>Reusing Definitions for Events, Commands, Parameters (refs)</h2>
+<p>It is possible to reuse similar parts of event, command and parameter definitions by using the <code>ref</code> keyword. The example below uses a reference to an event (<code>engMode</code>) in another event (<code>engMode2</code>):</p>
+<pre><code>  events = [
+    {
+      name = engMode
+      description = &quot;LGS WFS engineering mode enabled&quot;
+      archive = false
+      parameters = [
+        ...
+      ]
+    }
+    {
+      name = engMode2
+      description = &quot;LGS WFS engineering mode 2 enabled&quot;
+      archive = true
+      ref = engMode
+    }
+</code></pre>
+<p>In the above example, the event <code>engMode2</code> will have the same settings and parameters as <code>engMode</code>, except for <code>description</code> and <code>archive</code>, which are overridden. Any fields, which are not set, are inherited from the referenced event. This works for events, commands and parameters, as shown in the parameter reference example below:</p>
+<pre><code>      parameters = [
+        {
+          name = mode3
+          ref = engMode/parameters/mode
+        }
+
+</code></pre>
+<p>In the above example, the parameter <code>mode3</code> will be exactly the same as the <code>mode</code> parameter in the <code>engMode</code> event in the same component. You could also specify a different description field or any other parameter fields that should override the ones defined for mode.</p>
+<p>The syntax of the <code>ref</code> value is flexible and allows you to reference any event, command or parameter in any component within the same subsystem. You can use a full path to specify a reference to an item in another component, or an abbreviated path for items in the same scope. The full syntax of a ref is something like this:</p>
+<p><em>componentName/section/eventName[/parametersSection/paramName]</em></p>
+<p>For example, to reference an event, observe event or current state, use:</p>
+<ul>
+  <li>componentName/events/eventName</li>
+  <li>or componentName/observeEvents/eventName</li>
+  <li>or componentName/currentState/eventName</li>
+  <li>or events/eventName, &hellip; (if in the same component)</li>
+  <li>or just eventName (if in the same component and event type section)  For commands received, the syntax is similar:</li>
+  <li>componentName/receive/commandName</li>
+  <li>or just commandName (if in the same component)</li>
+</ul>
+<p>The syntax for references to parameters of events adds the <code>parameters</code> keyword and the parameter name:</p>
+<ul>
+  <li>componentName/events/eventName/parameters/paramName</li>
+</ul>
+<p>or abbreviated as described above for events:</p>
+<ul>
+  <li>observeEvents/eventName/parameters/paramName (in same component)</li>
+  <li>or eventName/parameters/paramName (in same component and events section)</li>
+</ul>
+<p>Or just paramName (if in the same parameters section)</p>
+<p>The syntax for parameters of commands is similar. Here you need to specify if the parameters appear in the “parameters” section or in the “resultType”.</p>
+<ul>
+  <li>componentName/receive/commandName/parameters/paramName</li>
+  <li>or componentName/receive/commandName/resultType/paramName</li>
+</ul>
+<p>Or abbreviated as described above.</p>
+<p>See the <a href="https://github.com/tmtsoftware/icd/blob/master/examples/3.0/TEST/lgsWfs/publish-model.conf">example model files</a> in the icd sources for some examples of the <code>ref</code> keyword.</p><div class="callout note "><div class="callout-title">Note</div>
+<p>If there is an error in the reference, the error message is displayed in the log output of the icd-db command, if it is used, and also inserted in the generated HTML or PDF document (in the details section).</p></div>
+<p>Below is an example that demonstrates some of the <code>ref</code> syntax for event parameters:</p>
+<pre><code>  events = [
+    {
+      name = engMode3
+      description = &quot;LGS WFS engineering mode enabled 3&quot;
+      archive = true
+      parameters = [
+        {
+          // Example reference to a parameter in this component
+          name = mode3
+          ref = engMode/parameters/mode
+        }
+        {
+          // Example reference to a parameter in this component (using wrong ref to produce error in HTML/PDF output)
+          name = mode3Error
+          ref = engMode/parameters/modeXXX
+        }
+</code></pre><div class="callout note "><div class="callout-title">Note</div>
+<p>Note: An earlier version of the icd software used the terms &ldquo;attributes&rdquo; for events parameters and &ldquo;args&rdquo; for command parameters. These have been renamed to &ldquo;parameters&rdquo; for compatibility with CSW, however for backward compatibility the previous names are also allowed in refs.</p></div>
+<h2><a href="#using-jsonnet-for-model-files" name="using-jsonnet-for-model-files" class="anchor"><span class="anchor-link"></span></a>Using Jsonnet for Model Files</h2>
+<p>Normally, the icd model files are written in <a href="https://github.com/lightbend/config/blob/main/HOCON.md">HOCON</a> format, a simplified JSON format, and have a <code>.conf</code> suffix. In some cases, you may want to have more features available, for example to refer to similar definitions in may different places. The icd software also supports model files using the <a href="https://jsonnet.org/">jsonnet</a> data templating language, which lets you define variables and functions and reuse them. To do this, replace the <code>.conf</code> suffix with <code>.jsonnet</code> (or <code>.libsonnet</code> for jsonnet files you want to import) and follow the syntax rules for jsonnet, so that the resulting JSON, after being processed by jsonnet conforms to the icd JSON schema. The icd software will automatically preprocess the jsonnet model files when they are imported into the icd database.</p>
+<p>For example, you can add some common, reusable, top level definitions in a file <code>utils.libsonnet</code>:</p>
+<pre><code>// Define a common event
+{
+  heartbeat: {
+    name: &#39;heartbeat&#39;,
+    description: &#39;Heartbeat event description...&#39;,
+    parameters: [
+      {
+        name: &#39;heartbeat&#39;,
+        description: &#39;software heartbeat&#39;,
+        type: &#39;integer&#39;,
+      },
+    ],
+  },
+
+  // Defines a function to generate a common event model based on the given arguments
+  commonEventFunc(eventName, paramName, typeName):: {
+    name: eventName,
+    description: eventName + &#39; description.&#39;,
+    archive: false,
+    parameters: [
+      {
+        name: paramName,
+        description: &#39;Description for &#39; + paramName,
+        type: typeName,
+      },
+    ],
+  },
+}
+</code></pre>
+<p>And then reference these definition in a <code>publish-model.jsonnet</code> file for a different component. Below is an example <code>publish-model.jsonnet</code> file that imports reusable jsonnet code:</p>
+<pre><code>// Import common function defined in another file
+local utils = import &#39;../utils.libsonnet&#39;;
+
+{
+  subsystem: &#39;TEST&#39;,
+  component: &#39;jsonnet.example&#39;,
+
+  // comments can use // or #
+  publish: {
+    description: |||
+      Multi-line descriptions
+      use this syntax in jsonnet
+    |||,
+
+    events: [
+      // define two similar events using imported function
+      utils.commonEventFunc(&#39;myEvent1&#39;, &#39;param1&#39;, &#39;boolean&#39;),
+      utils.commonEventFunc(&#39;myEvent2&#39;, &#39;param2&#39;, &#39;string&#39;),
+
+      // Insert an imported event definition
+      utils.heartbeat,
+
+      // define another event
+      {
+        name: &#39;state&#39;,
+        // Import the description text
+        description: importstr &#39;../importRaw.txt&#39;
+,
+        archive: false,
+        parameters: [
+          {
+            name: &#39;state&#39;,
+            description: &#39;Detector state&#39;,
+            enum: [&#39;EXPOSING&#39;, &#39;READING&#39;, &#39;IDLE&#39;, &#39;ERROR&#39;],
+          },
+        ],
+      },
+    ],
+  },
+}
+</code></pre>
+<p>The above example defines two events (myEvent1 and myEvent2) that are similar, but configured based on the given function arguments. The heartbeat event is used as is. The state event is defined in the usual way (for JSON), but imports the description text from a file.</p>

+<p>If the parameter type is an array, there are some special tags for describing it. The minItems and maxItems parameters can be used for 1-Dimensional arrays and is especially useful for arrays with a variable length. However, for other arrays, including higher dimensional arrays, a dimensions tag can be used, with a syntax of [x,y,z,…] where x, y, and z are positive integers specifying the size of each dimension. Note that the CSW framework only supports numerical array and matrix types, although each item of the array or matrix can be a list of one or more values.</p>
+<p>To describe the items in an array, an “items” block is used. Within it, the type is set using the type field. The mimimum, maximum, exclusiveMinimum, and exclusiveMaximum fields may be used as well.</p>
+<p>In the CSW framework, only numerical array parameter types are supported, however since every parameter may have multiple values, it is usually not necessary to declare the type as an array.</p>

+<h2><a href="#other-event-types" name="other-event-types" class="anchor"><span class="anchor-link"></span></a>Other Event Types</h2>
+<p>Some events signal an occurrence of an activity in a component that other systems use to synchronize actions. Some, like observe events, are system defined. They are not periodic, so a rate is not necessary. The <code>publish-model.conf</code> file has a container for events the component publishes that includes an array of one or more events.</p>
+<p>Current states, which are published by HCDs for assemblies, are not actually events, but are structured the same, and written in the <code>currentStates</code> block instead of the <code>events</code> block.</p>
+<p>Events and current states have the same schema, with a <code>name</code>, <code>description</code>, and parameters describing the event data. Below is an example current state event described in the <code>publish-model.conf</code> file:</p>
+<pre><code>  currentStates = [
+    {
+      name = &quot;nacqUnarchived&quot;
+      archive = false
+      parameters = [

+          enum = [EXPOSING, READING, IDLE, ERROR]
+        }
+        {
+          name = nacq_period
+          description = &quot;NACQ continuous read period&quot;
+          type = float
+          units = seconds
+        }
+        {
+          name = nacq_contRead
+          description = &quot;NACQ continuous read state enabled&quot;

+<p><img src="../images/modelFiles/currentStateExample1.png" /></p>
+<h2><a href="#service-model-file" name="service-model-file" class="anchor"><span class="anchor-link"></span></a>Service Model File</h2>
+<p>Another optional icd model file is <code>service-model.conf</code>. It is used to describe HTTP services provided by or consumed by a component. The actual HTTP services are described in <a href="https://swagger.io/specification/">OpenAPI</a> files that are also stored in the icd database.</p>
+<p>On the consumer side, the file can indicate which routes of the HTTP service it uses.</p>
+<p>Here is an example consumer service-model.conf:</p>
+<pre><code>subsystem = TEST
+component = env.ctrl
+
+requires = [
+  {
+    subsystem = TEST2
+    component = SegmentService
+    name = esw-segment-db
+    // Optional routes / paths used
+    paths = [
+      {
+        path = /setPosition
+        method = post
+      },
+      {
+        path = /currentPositions
+        method = get
+      }
+    ]
+  }
+]
+</code></pre>
+<p>The above example states that the component uses the HTTP methods <code>POST /setPosition</code> and <code>GET /currentPositions</code> from the service. The paths are optional and just for information. The generated documentation for an ICD between two subsystems or components will only display the parts of HTTP services that are declared as being used (in the paths array). By default, if the paths are not specified, the complete service API will be included in the ICD documentation.</p>
+<p>In the example <code>service-model.conf</code> file from a service provider below, the line:</p>
+<pre><code>openApi = esw-segment-db.json
+</code></pre>
+<p>points to the OpenAPI definition for the HTTP service that is being provided (The OpenAPI file should be in the same directory as the <code>service-model.conf</code> file and can be in JSON or YAML format and have the suffix <code>.json</code>, <code>.yaml</code> or <code>.yml</code>). Both the service-model information and the contents of the OpenAPI file are stored in the icd database where they are used to produce documentation (YAML files are first converted to JSON).</p>
+<p>service-model.conf:</p>
+<pre><code>subsystem = TEST2
+component = SegmentService
+
+provides = [
+  {
+    name = esw-segment-db
+    description = &quot;HTTP API to ESW Segment DB service, used for keeping track of TMT mirror segments&quot;
+    openApi = esw-segment-db.json
+  }
+]
+</code></pre>
+<p>The screenshot below shows how the above service provider info is displayed in the icd web app:</p>
+<p><img src="../images/modelFiles/seg-service.png" /></p>
+<p>If you click on the small button in the Name column, the detailed display is toggled open or closed. If you click on the link next to it, the documentation for the HTTP service is opened in a new tab. The format of the documentation for HTTP services is different from that of events, since it is provided by the <a href="https://swagger.io/tools/swagger-ui/">swagger-ui</a> library. The PDF version is somewhat simpler and is provided by the <a href="https://swagger.io/tools/swagger-codegen/">swagger-codegen</a> command line application.</p>
+<p>Note that each component can declare multiple services consumed and/or provided in the <code>service-model.conf</code> file. You can find example <code>service-model.conf</code> files and OpenAPI files in the <a href="https://github.com/tmtsoftware/icd/tree/master/examples/3.0">examples/3.0</a> directory in the icd sources.</p>

+<p>Events have been redesigned for the CSW PDR. Components write their data and other systems sample it at the rate they need. <code>requiredRate</code> allows a component to state a rate they require to operate properly. It’s up to the publisher to make sure that they can provide that rate. This is part of checking interfaces.</p>
+<p>There is minimal documentation for subscribe items. The full description of an item belongs with the publisher, not the subscriber. The subscriber is only referencing its use of information published by another component.</p>
+<p>The <code>name</code> field must match the name of published item in another component. It must be spelled correctly. The best way is to browse the API of the source system and copy the full path.</p>
+<p>By default, subscribed events are not displayed in API documents. To include them, pass the <code>–clientApi</code> option to <code>icd-db</code>, or select the <code>Include client API information</code> check box in the web app.</p>
+<p>The figure below shows a section of the display of the icd web app for the above <code>subscribe-model.conf</code> file. The descriptions are looked up in the database (originally from <code>publish-model.conf</code> files in other components).</p>

To support the Systems Engineering change control process by understanding how planned interface changes influence the software system.

One approach might be to use/extend a source code documentation markup tool such as Doxygen or the 15+ other products a Google search on software documentation shows. The reason this approach wasn’t taken is that the problem is not about documenting source code, it is modeling components and interfaces and delivering a database that provides a basis for understanding and tracking interfaces and their changes. The models need to drive the source, not the other way around. Documentation tools can generate documents but extracting information and putting it into a database is not the scope of these tools. The primary need is to have a database of interfaces and delivering interface documentation is a second, although important, side effect.

They are briefly described here, with more details provided in subsequent sections.\nThe workflow proceeds from left to right.\nThe TIO developer, using Common Software for his/her components, creates component model files. These files are validated and ingested into the ICD Model File Database using either the icd-db command or a web application called icdwebserver. These were developed to work with the ICD Model File Database and provide the functionality the users of the system need. The model files are stored and published in Git repositories on GitHub. The icd-git application can be used to sync the local database with the published versions on GitHub. The icd web app also gets its information from the published versions on GitHub, in addition to any unpublished versions that a developer is working with locally. The icd-viz command line application can be used to generate a graph of component or subsystem relationships. This feature requires that graphviz is installed and is also available in the icd web app. The icd-fits command can be used to view information about FITS keywords and their source events.","title":"Overview"},{"location":"/idbs/overview.html#icd-db","text":"The icd-db program exists to validate and ingest model files into a local ICD Model File Database. When creating or modifying the models, this feature can be used to incorporate working versions of the files into the database system. The icd-db program also allows some informative queries to be performed directly on the database, showing what subsystem and components exist in the database, and information about them such as data rates, data types, and units used. Note that these operations only work on the models that exist in the local version of the database, and do not access the released models on the GitHub repository.","title":"icd-db"},{"location":"/idbs/overview.html#icdwebserver","text":"The icdwebserver web application provides the IDBS user application interface. The browser-based user interface allows the ingesting of model files, publishing them, and displaying versioned APIs for each component. An API is defined as all the functionality of a component or subsystem including inputs and outputs. An ICD is produced by taking the intersection of two subsystem API documents.\nThe IDBS browser provides the ability to browse the APIs for both published and unpublished models. The published APIs are constructed from models obtained from the git repository which stores the released versions, and the unpublished APIs are constructed by accessing the models stored in the local database that have been ingested using the icd-db program or the web app.\nThe current version of the IDBS browser user interface includes the following features:\nAllows browsing all the subsystems and their components (including previously published versions as well as unpublished working versions). View the API for a subsystem or an individual component. Browse interfaces between subsystems, or components within subsystems. Upload directories containing the model files for a subsystem API Publish APIs and ICDs (if enabled, for TIO SE use only) Print ICD or API information from the browser (using browser print). Export an API or ICD as a PDF document. Show the publish history of an API or ICD and compare the differences between versions Generate a PDF document that shows the amount of storage required for all archived events Generate a graph of component or subsystem relationships\nA public (password-protected) ICD web service has been set up that allows users to view the APIs and ICDs of all TIO subsystems and components. The uploading functionality of this web service has been disabled; new model files must be committed to the GitHub repository to add new versions to this system, which are automatically added to the web service whenever the system is refreshed.

Since this tool is mainly intended to be used by the Systems Engineering group, it is not documented here.\nIt is also possible to publish APIs and ICDs using the web app (icdwebserver) and this is now the preferred way to do it.

There are a number of options for controlling what is displayed and the format of the image produced.\nThis application relies on graphviz to generate the graph from a description generated in the dot graph description language. Run icd-viz –help to see the command line options (These are also listed in the README.md file for the icd-viz subproject on GitHub). Note that the icd web app also provides a user interface for most of these features. See Using the Web Interface for more information on that.\nThe icd-viz command lets you specify one or more TIO components or subsystems (in which case all components in the subsystem are used). These are the primary nodes of the graph, drawn as solid ovals. Then, all of the components that publish events for these components or subscribe to events from these components are added to the graph (as dashed ovals). The graph edges indicate the flow of events and commands between the components and optionally show any errors, such as events subscribed from publishers that do not exist, or published events with no subscribers.\nThe default colors used for the graph can be found in icd/icd-viz/src/main/resources/reference.conf and can also be overridden with a command line option like -Dicd.viz.color.IRIS=darkgreen (replace IRIS with the subsystem). The colors should be valid Graphviz colors.\nNote The design of the icd-viz application is based on previous work (NIC/scripts/icdRelationships.py) from Ed Chapin of the NRC.\nExample icd-viz command line usage:\nPlot all interfaces for a particular component to the screen, label events and commands, and show missing events and commands:\nicd-viz --components iris.oiwfs.poa --missingcommands true --missingevents true --commandlabels true --eventlabels true\nBelow is the resulting image from the above command:","title":"icd-viz"},{"location":"/idbs/overview.html#icd-fits","text":"The icd-fits command line application can be used to manually ingest FITS dictionary files into the icd database and produce tables in PDF and other format containing information about all the FITS keywords and the subsystem events that are the source of the keyword values. There are command line options that allow you to filter the list of keywords by source subsystem and component as well as by tag.\nThe command can also be used to merge the FITS keyword definitions found in the publish model files with the current FITS dictionary stored in the icd database to produce a new FITS dictionary, where the keyword definitions in the publish model files override the ones previously in the FITS dictionary. This can be used to update the FITS-Dictionary.json file in the tmt-icd DMS-Model-Files GitHub repository, which is loaded automatically whenever the DMS model files are ingested into the icd database.\nThe main source for the FITS dictionary files is in the FITS-Dictionary directory in the tmt-icd DMS-Model-Files GitHub repository. One file there, FITS-Dictionary.json, lists information about the FITS keywords and related subsystem, component, event, and parameter. Another file, FITS-Channels.conf, lists the available channel names for FITS keywords that have multiple source events or parameters. The third file, FITS-Tags.conf, assigns tags to the keywords, such as SL (Seeing-Limited), DL (Diffraction-Limited), or the WFOS, IRIS or MODHIS instruments.\nSome keywords can come from multiple sources or channels, such as imaging or IFS. This information is also included in the FITS Dictionary JSON file above. When you specify the FITS keyword in an event’s parameter description in publish-model.conf, in most cases it is enough to just list the keyword name with keyword = keyname. If the same FITS keyword has multiple different source events/parameters, it needs to be assigned a channel as well. For example: channel = IFS. The channel name needs to be one of the predefined names for that subsystem listed in FITS-Channels.conf.\nFor more details, see Using the icd-fits command line app.\nNote that at the time of writing these files are still in development and may contain incorrect information.","title":"icd-fits"},{"location":"/idbs/overview.html#implementation-details","text":"The IDBS is implemented in Scala, a JVM-based language (http://www.scala-lang.org).

This workflow is shown in the context of the TMT Software Quality Assurance Plan and Software Development Process (SQUAP and SDP) [RD01], which describes the entire software development process.\nOMOA components consist of HCDs, Assemblies, Sequencers, and Applications. The components are developed incrementally and independently of other subsystem’s components.\nEach component has a public interface or application programming interface (API). The API is based on the services provided by common software. The API shows all the available functionality of a component and subsystem.\nEach TIO software ICD consists of a framework part and a detailed part. The framework part is written in Word according to the TIO Systems Engineering template. The detailed part is generated from the ICD-DB and can change more frequently without requiring updates to the framework document - at least in the case where the framework information does not change.\nA component developer creates a set of model files for each component that describes the component and its interfaces (see the section on model files). These model files are text files. When the component interface changes, the developer updates the model files, validates them, and when ready, checks them into a dedicated repository for model files at the GitHub site: (https://github.com/tmt-icd).\nWhen working on or changing an interface used by another TIO subsystem that will be part of an ICD, the component developer should work with the other subsystem developers to determine the correct functionality and API.\nOnce the model files are checked in, TIO Systems Engineering determines when the new version of a subsystem’s API can be published and given a new incremental version number. Systems Engineering will review any changes that impact other subsystems and ensure they are aware of and agree with changes that will be part of an ICD. New releases of the API documents can be published and will be seen as published in the ICD-DB web user interface.\nTIO Systems Engineering also determines when a new ICD can be generated based on the APIs of the constituent subsystems and manages the publication of a new detailed ICD release. When published, the new ICD is also shown as published in the ICD-DB web user interface.\nNote It may be necessary to click the browser refresh button to see a newly published API or ICD that is not yet in the local icd database (The icd web app then automatically ingests any newly published APIs and ICDs into the local database).

Model files that provide information about the component and its interfaces are created for each of the components. This section describes the model files. The model files are named: component-model, command-model, publish-model, alarm-model, and subscribe-model. In addition, each subsystem has a single subsystem-model file and may have one or more $subsystem-icd-model files that contain additional information about the interface between two subsystems. Separate files were created (rather than one larger file) in order to keep the configuration files simpler and easier to type.\nThe following table shows the different types of model files and what they describe:\nModel File Description subsystem-model.conf Contains high-level information about the subsystem that contains a group of components. There is one subsystem-model.conf file per subsystem. component-model.conf Contains high-level component information. There is one component-model.conf file per component. command-model.conf Describes the configuration commands the component supports. Also describes components and commands the component may send to other components. There is at most one command-model.conf file per component. publish-model.conf Describes events the component publishes using Event Services. There is at most one publish-model.conf file per component. service-model.conf Describes HTTP services provided or consumed by the component. The HTTP services themselves are described in OpenAPI files. alarm-model.conf Describes alarms the component publishes using the Alarm Service. There is at most one alarm-model.conf file per component. subscribe-model.conf Describes events the component subscribes to using Event Services. There is at most one subscribe-model.conf file per component. $subsystem-icd-model.conf Where $subsystem is the name of one of the other TMT subsystems, for example: IRIS-icd-model.conf. These files may contain additional information about the interface between the subsystem being defined and another subsystem (IRIS in this example).\nThe component is only required to create a command-model.conf, publish-model.conf, alarm-model.conf, or subscribe-model.conf if it provides or uses the features described in the model files (i.e. if the component does not subscribe to events, then a subscribe-model.conf file is not needed).\nModel files are text files written in a superset of JSON called HOCON, which provides syntactic sugar for writing JSON, but can be exported as pure JSON. In addition, most fields support GitHub style MarkDown as well as HTML tags. LaTeX math markup and UML are also supported (see below). In addition, it is possible to reuse certain repetitive definitions, such as those for events, commands and parameters by using the ref keyword in the model files to refer to another definition. The syntax is described below. Each type of model file has a schema which specifies the allowed structure of the contents within, including specifying the optional and required items, item types, allowed ranges, etc. The following sections describe each of the model files including necessary fields.","title":"Model Files"},{"location":"/modelFiles/modelFiles.html#markdown-support-math-uml-dot","text":"In addition to using standard GitHub style MarkDown in descriptions, you can also insert LaTeX math formulas: Here is an example description text containing an inline math formula:\ndescription = \"\"\"\nHere is an example using LaTeX math: $`\\frac{d}{dx}\\left( \\int_{0}^{x} f(u)\\,du\\right)=f(x)`$.\nAnd here is another: $`[x^n + y^n = z^n]`$.\n“””\nAnd this is the inline math formula displayed from the above input:\nBlock math formulas are delimited by\n```math\n\n```\nFor example:\nDescription = “””\nHere is an example using LaTeX math: $`\\frac{d}{dx}\\left( \\int_{0}^{x} f(u)\\,du\\right)=f(x)`$.\nAnd here is another: $`[x^n + y^n = z^n]`$.\n\nThis is a math block:\n\n```math\n$$\\idotsint_V \\mu(u_1,\\dots,u_k) \\,du_1 \\dots du_k$$\n```\n\nand another:\n\n```math\n\\frac{n!}{k!(n-k)!} = \\binom{n}{k}\n```\n\nand a matrix:\n\n```math\nA_{m,n} =\n \\begin{pmatrix}\n  a_{1,1} & a_{1,2} & \\cdots & a_{1,n} \\\\\n  a_{2,1} & a_{2,2} & \\cdots & a_{2,n} \\\\\n  \\vdots  & \\vdots  & \\ddots & \\vdots  \\\\\n  a_{m,1} & a_{m,2} & \\cdots & a_{m,n}\n \\end{pmatrix}\n```\n“””\nThe display for the above description is shown below:\nUML (PlantUML) and Graphviz Dot are also supported, delimited by\n```uml\n```\nFor example, below are some embedded UML blocks in a model file description text:\nDescription = “””\n\nand a small one:\n\n```uml\nBob -[#red]> Alice : hello\nAlice -[#0000FF]->Bob : ok\n```\n\nNote that according to https://plantuml.com/dot you can also use Graphviz/Dot diagrams instead of UML:\n\n```uml\ndigraph foo {\n  node [style=rounded]\n  node1 [shape=box]\n  node2 [fillcolor=yellow, style=\"rounded,filled\", shape=diamond]\n  node3 [shape=record, label=\"{ a | b | c }\"]\n\n  node1 -> node2 -> node3\n}\n```\n\"\"\"\nBelow is the display produced from the above description text:","title":"Markdown Support, Math, UML, Dot"},{"location":"/modelFiles/modelFiles.html#inner-document-links","text":"It is possible to make inner-document links to existing anchors using Markdown syntax.

Any fields, which are not set, are inherited from the referenced event. This works for events, commands and parameters, as shown in the parameter reference example below:\nparameters = [\n        {\n          name = mode3\n          ref = engMode/parameters/mode\n        }\nIn the above example, the parameter mode3 will be exactly the same as the mode parameter in the engMode event in the same component. You could also specify a different description field or any other parameter fields that should override the ones defined for mode.\nThe syntax of the ref value is flexible and allows you to reference any event, command or parameter in any component within the same subsystem. You can use a full path to specify a reference to an item in another component, or an abbreviated path for items in the same scope. The full syntax of a ref is something like this:\ncomponentName/section/eventName[/parametersSection/paramName]\nFor example, to reference an event, observe event or current state, use:\ncomponentName/events/eventName or componentName/observeEvents/eventName or componentName/currentState/eventName or events/eventName, … (if in the same component) or just eventName (if in the same component and event type section) For commands received, the syntax is similar: componentName/receive/commandName or just commandName (if in the same component)\nThe syntax for references to parameters of events adds the parameters keyword and the parameter name:\ncomponentName/events/eventName/parameters/paramName\nor abbreviated as described above for events:\nobserveEvents/eventName/parameters/paramName (in same component) or eventName/parameters/paramName (in same component and events section)\nOr just paramName (if in the same parameters section)\nThe syntax for parameters of commands is similar. Here you need to specify if the parameters appear in the “parameters” section or in the “resultType”.\ncomponentName/receive/commandName/parameters/paramName or componentName/receive/commandName/resultType/paramName\nOr abbreviated as described above.\nSee the example model files in the icd sources for some examples of the ref keyword.\nNote If there is an error in the reference, the error message is displayed in the log output of the icd-db command, if it is used, and also inserted in the generated HTML or PDF document (in the details section).\nBelow is an example that demonstrates some of the ref syntax for event parameters:\nevents = [\n    {\n      name = engMode3\n      description = \"LGS WFS engineering mode enabled 3\"\n      archive = true\n      parameters = [\n        {\n          // Example reference to a parameter in this component\n          name = mode3\n          ref = engMode/parameters/mode\n        }\n        {\n          // Example reference to a parameter in this component (using wrong ref to produce error in HTML/PDF output)\n          name = mode3Error\n          ref = engMode/parameters/modeXXX\n        }\nNote Note: An earlier version of the icd software used the terms “attributes” for events parameters and “args” for command parameters.

In some cases, you may want to have more features available, for example to refer to similar definitions in may different places. The icd software also supports model files using the jsonnet data templating language, which lets you define variables and functions and reuse them. To do this, replace the .conf suffix with .jsonnet (or .libsonnet for jsonnet files you want to import) and follow the syntax rules for jsonnet, so that the resulting JSON, after being processed by jsonnet conforms to the icd JSON schema. The icd software will automatically preprocess the jsonnet model files when they are imported into the icd database.\nFor example, you can add some common, reusable, top level definitions in a file utils.libsonnet:\n// Define a common event\n{\n  heartbeat: {\n    name: 'heartbeat',\n    description: 'Heartbeat event description...',\n    parameters: [\n      {\n        name: 'heartbeat',\n        description: 'software heartbeat',\n        type: 'integer',\n      },\n    ],\n  },\n\n  // Defines a function to generate a common event model based on the given arguments\n  commonEventFunc(eventName, paramName, typeName):: {\n    name: eventName,\n    description: eventName + ' description.',\n    archive: false,\n    parameters: [\n      {\n        name: paramName,\n        description: 'Description for ' + paramName,\n        type: typeName,\n      },\n    ],\n  },\n}\nAnd then reference these definition in a publish-model.jsonnet file for a different component. Below is an example publish-model.jsonnet file that imports reusable jsonnet code:\n// Import common function defined in another file\nlocal utils = import '../utils.libsonnet';\n\n{\n  subsystem: 'TEST',\n  component: 'jsonnet.example',\n\n  // comments can use // or #\n  publish: {\n    description: |||\n      Multi-line descriptions\n      use this syntax in jsonnet\n    |||,\n\n    events: [\n      // define two similar events using imported function\n      utils.commonEventFunc('myEvent1', 'param1', 'boolean'),\n      utils.commonEventFunc('myEvent2', 'param2', 'string'),\n\n      // Insert an imported event definition\n      utils.heartbeat,\n\n      // define another event\n      {\n        name: 'state',\n        // Import the description text\n        description: importstr '../importRaw.txt'\n,\n        archive: false,\n        parameters: [\n          {\n            name: 'state',\n            description: 'Detector state',\n            enum: ['EXPOSING', 'READING', 'IDLE', 'ERROR'],\n          },\n        ],\n      },\n    ],\n  },\n}\nThe above example defines two events (myEvent1 and myEvent2) that are similar, but configured based on the given function arguments.

Note that coord (CSW Coord) is a base type that can be used for any of the coordinate types.\nIf the parameter type is an array, there are some special tags for describing it. The minItems and maxItems parameters can be used for 1-Dimensional arrays and is especially useful for arrays with a variable length. However, for other arrays, including higher dimensional arrays, a dimensions tag can be used, with a syntax of [x,y,z,…] where x, y, and z are positive integers specifying the size of each dimension. Note that the CSW framework only supports numerical array and matrix types, although each item of the array or matrix can be a list of one or more values.\nTo describe the items in an array, an “items” block is used. Within it, the type is set using the type field. The mimimum, maximum, exclusiveMinimum, and exclusiveMaximum fields may be used as well.\nIn the CSW framework, only numerical array parameter types are supported, however since every parameter may have multiple values, it is usually not necessary to declare the type as an array.\nNote that the value of the mimimum, maximum, exclusiveMinimum, and exclusiveMaximum fields may be numeric or “inf” or “-inf” (for +/- infinity).","title":"Parameter Types"},{"location":"/modelFiles/modelFiles.html#units","text":"The CSW software defines a list of standard units that are accepted.

The generated documentation for an ICD between two subsystems or components will only display the parts of HTTP services that are declared as being used (in the paths array). By default, if the paths are not specified, the complete service API will be included in the ICD documentation.\nIn the example service-model.conf file from a service provider below, the line:\nopenApi = esw-segment-db.json\npoints to the OpenAPI definition for the HTTP service that is being provided (The OpenAPI file should be in the same directory as the service-model.conf file and can be in JSON or YAML format and have the suffix .json, .yaml or .yml). Both the service-model information and the contents of the OpenAPI file are stored in the icd database where they are used to produce documentation (YAML files are first converted to JSON).\nservice-model.conf:\nsubsystem = TEST2\ncomponent = SegmentService\n\nprovides = [\n  {\n    name = esw-segment-db\n    description = \"HTTP API to ESW Segment DB service, used for keeping track of TMT mirror segments\"\n    openApi = esw-segment-db.json\n  }\n]\nThe screenshot below shows how the above service provider info is displayed in the icd web app:\nIf you click on the small button in the Name column, the detailed display is toggled open or closed. If you click on the link next to it, the documentation for the HTTP service is opened in a new tab. The format of the documentation for HTTP services is different from that of events, since it is provided by the swagger-ui library. The PDF version is somewhat simpler and is provided by the swagger-codegen command line application.\nNote that each component can declare multiple services consumed and/or provided in the service-model.conf file. You can find example service-model.conf files and OpenAPI files in the examples/3.0 directory in the icd sources.","title":"Service Model File"},{"location":"/modelFiles/modelFiles.html#alarms","text":"An alarm is published to mark an abnormal condition that requires attention.

ICDs are then also published as versioned documents that depend on published subsystem API versions. The publishing of APIs and ICDs is a role of Systems Engineering and is therefore password protected. It can be performed using the icd web app (requires special command line option to icdwebserver). The web interface can be used to produce draft ICD and API documents that can be shared prior to the official publishing by Systems Engineering.","title":"Using the Web Interface"},{"location":"/webapp/webapp.html#starting-the-icd-web-app","text":"To start the icd web app, run:\nicdwebserver\nBy default, this starts the web app on port 9000 on localhost (http://localhost:9000).

By using this feature, you can upload an entire subsystem of model files in one click. If your browser does not support uploading directories, try using Chrome.\nIf the web server is running on your own machine, go to http://localhost:9000. The empty website is shown in the following figure. The upload button is shown circled in red (the red circle does not appear in the UI!)\nNote The icd web app automatically ingests any released APIs and ICDs on startup by downloading any missing versions from the GitHub repos under https://github.com/tmt-icd.

The parent directory should be imported at least once to get the subsystem-model.conf file, which is a sibling of the component directories.\nSelecting the directory will cause the web service to upload all the contained files and import them into the model file database. The program shows progress and the status area shows any problems. The following figure shows the result of uploading the APS-Model-Files directory. It shows a progress bar in blue at 100%. Files other than icd model files are ignored and a warning is displayed (in case the file name was misspelled).\nThat’s all for uploading. This can be done over and over and nothing is permanent until the API is published.","title":"Procedure for Uploading Files"},{"location":"/webapp/webapp.html#view-a-subsystem-api","text":"The next example shows how to view a subsystem API.\nWith the subsystem uploaded, its API can be viewed in the browser by selecting the subsystem in the subsystem pull-down menu at the top of the screen. The menu shows all the subsystems found in the local database. The browser content area will redraw with the contents of the selected subsystem. The result of selecting APS is shown in the following figure.\nA couple of things to note: The area to the left shows a number of links. This area has one link for each component in the subsystem.\nThe content area displays all the components for the subsystem. Clicking on one of the component links jumps to the given component’s information.\nThe displayed API is constructed from the current versions of the models in the database, and is therefore considered an unpublished working version. Although APIs are published by Systems Engineering, the system allows the viewing of all versions of published APIs as well as the working version as shown above (Note: the published versions of the APIs are ingested directly from the GitHub repository, whereas the unpublished models are obtained only from the local database). To do this, select the desired version number in the dropdown menu next to the subsystem name.\nNote that “master” also appears in the list of versions and is linked to the contents of the master branch of a subsystem on GitHub. The contents of the master branch are automatically uploaded to the icd database (if there was a change) whenever you refresh the web app or when running the command: icd-git --ingestMissing.\nThere are two checkboxes in the Select dialog that are only enabled for APIs (when only one subsystem is selected).\nInclude client API information (subscribed events, sent commands) Search all TMT subsystems for API dependencies\nSelecting the first checkbox will include sections for subscribed events and sent commands in the API document, as well as columns for subscribers of published events and senders of received commands.

There are also tools for comparing PDF files, which might be useful.\nTo view the API history, select a subsystem, and press the History button. The content area changes as shown in the following:","title":"View API History"},{"location":"/webapp/webapp.html#create-and-view-an-icd","text":"An ICD is formed by taking the intersection of the APIs of two TMT subsystems. That means in order to create an ICD there must be at least two subsystems in the database. The TCS API is created from various subsystem to TCS ICDs that exist and the TCS CODR SDD. The definitive TCS API will be a product of the TCS work packages.\nIt is possible to view ICDs with working/unpublished versions, with one unpublished version and one published version, or two published versions. ICDs can only be published between two published APIs.\nThis example will show how to view a working ICD between the published version 1.12 of the TCS API and the unpublished M1CS subsystem API.\nUpload all the working versions of the APIs needed to form an ICD. First select the version of the subsystem for the ICD. In the figure below the menu to the right of the subsystem shows the available versions. Version 1.12, the version published previously is selected. (To get back to the working version, select the asterisk in the menu.) Note that the content area says API for TCS 1.12 rather than the unpublished label.\nNext, select a second subsystem in the second subsystem menu as shown in the figure to below the Subsystem menu. The figure shows the available subsystems (some may be only local and others automatically ingested from the ICD GitHub repositories). TCS is also selectable since one subsystem component can have an ICD with another in the same subsystem. Selecting M1CS shows the following screenshot (without the red arrow). To get out of ICD mode and back to browsing APIs, select the top item (Select Subsystem) in the second subsystem menu on the Select tab.\nNote that the title shows ICD from TCS to M1CS (unpublished). This means that the displayed ICD is not published by Systems Engineering — it is a draft version.\nAlso note the circle on the screenshot below. The section “Events published by GLC” shows items published by the GLC component. The Subscriber column is a link to the component that subscribes to the event stream. The link can be selected to jump to the subscribing component, regardless of which of the two subsystems it is in.\nThe same is true for commands: There are links to the command senders for received commands.\nThe ability to see and display these links is one of the highest priority features for this project. This is one feature that is not possible with simpler documentation tools.","title":"Create and View an ICD"},{"location":"/webapp/webapp.html#view-icd-history","text":"Like an API, it’s possible to view the history of an ICD between two subsystems.\nWith a published ICD is selected, select the History button as was done in the about viewing an API history.

Ideally, we will just provide a link to the IDBS that reproduces the referenced ICD, but the PDF option in the toolbar allows outputting a PDF version with a table of contents and front page. The figure below shows a portion of the PDF output for our TCS to M1CS ICD Version 1.1.","title":"Print an ICD or API"},{"location":"/webapp/webapp.html#view-a-graph-of-component-relationships","text":"The Graph button in the Select tab displays a dialog for creating a graph of component and subsystem relationships. The graph is based on the selected subsystems and components, which we call the primary components. These are displayed as solid ovals. All the components that the primary components talk (via events or commands) to are then included as dashed ovals. The edges of the graph indicate the flow of events and commands between the components. References to events or commands that were never defined are displayed in red, as are components that do not exist.\nThe figure below shows the Select dialog with the Graph toolbar button and the IRIS.oiwfs.poa component selected:\nPressing the Graph button opens a dialog with options for the graph:\nNote that the graph is created using the GraphViz Dot language. See https://graphviz.org/ for an explanation of layouts and overlap handling. You can also use the icd-viz command line application to produce the same graph. The command line version lets you choose more than two primary components and save the Dot file.\nPressing Apply in the Graph dialog creates this graph for the selected IRIS component:\nThe default colors used for the graph can be found in the icd-viz reference.conf file and can also be overridden with a command line option like -Dicd.viz.color.IRIS=darkgreen (Replace IRIS with the subsystem and the color with a valid Graphviz color). A future version of the icd web app may include a tab in the graph options dialog for configuring the colors.\nHere is a legend for the generated graph:\nIn the above graph, you can see that oiwfs.poa is the primary component (represented as a solid oval). It publishes events to other components, such as IRIS.oiwfs.detector and AOESW.aosq and subscribes to events from NFIRAOS.rtc and TCS.cmIRIS. AOESW.aosq also sends commands to oiwfs.poa, however the command names are not listed, since that option was not selected in the graph dialog. The red question mark in IRIS indicates that oiwfs.poa publishes events that have no known subscribers. The other red arrows indicate that it also subscribes to some events that are not published anywhere (perhaps an error). Displaying these errors is optional. The figure below shows the same graph with the missing events option turned off and command labels turned on.","title":"View a Graph of Component Relationships"}]}

+<p>This section describes the web interface for IDBS. The idea is to show each of the possible steps.</p>
+<p>The browser-based user interface allows ingesting model files and displaying versioned “API”s for each component. An API is defined as all the public functionality of a component and subsystem including inputs and outputs. An ICD is produced by taking the intersection of two published subsystem API documents. ICDs are then also published as versioned documents that depend on published subsystem API versions. The publishing of APIs and ICDs is a role of Systems Engineering and is therefore password protected. It can be performed using the icd web app (requires special command line option to icdwebserver). The web interface can be used to produce draft ICD and API documents that can be shared prior to the official publishing by Systems Engineering.</p>
+<h2><a href="#starting-the-icd-web-app" name="starting-the-icd-web-app" class="anchor"><span class="anchor-link"></span></a>Starting the icd web app</h2>
+<p>To start the icd web app, run:</p>
+<pre><code>icdwebserver
+</code></pre>
+<p>By default, this starts the web app on port 9000 on localhost (<a href="http://localhost:9000)">http://localhost:9000)</a>. You can override this with options. For example:</p>
+<pre><code>icdwebserver -Dhttp.port=9898 -Dhttp.host=192.168.178.77
+</code></pre>
+<h2><a href="#upload-files" name="upload-files" class="anchor"><span class="anchor-link"></span></a>Upload Files</h2>
+<p>Installing the web app and uploading through the web app is not a bad way to check the content of model files because it also allows checking to see if the links are entered correctly. <code>icd-db</code> will only check that the files are syntactically correct.</p>
+<p>Uploading with the browser works best with recent browser versions that support uploading a directory including all files in the directory. By using this feature, you can upload an entire subsystem of model files in one click. If your browser does not support uploading directories, try using Chrome.</p>
+<p>If the web server is running on your own machine, go to <a href="http://localhost:9000">http://localhost:9000</a>. The empty website is shown in the following figure. The upload button is shown circled in red (the red circle does not appear in the UI!)</p>

+<p>The icd web app automatically ingests any released APIs and ICDs on startup by downloading any missing versions from the GitHub repos under <a href="https://github.com/tmt-icd">https://github.com/tmt-icd</a>. Then you can upload any directories containing model files that you are working on. These will be the considered the “working version” or “*” in the subsystem version menu.</p></div>

+<ol>
+  <li>Select the upload button in the web app. The following figure shows the web page after selecting the upload button:</li>
+</ol>
+<p><img src="../images/webapp/uploadFiles2.png" /></p>
+<ol>
+  <li>Select the <code>Choose Files</code> button and navigate to the directory of your model files. It can be a directory holding a single component or a directory containing other directories where each contained directory includes one component as shown in the following figure. The parent directory should be imported at least once to get the <code>subsystem-model.conf</code> file, which is a sibling of the component directories.</li>
+</ol>
+<p><img src="../images/webapp/fileTree.png" /></p>
+<ol>
+  <li>Selecting the directory will cause the web service to upload all the contained files and import them into the model file database. The program shows progress and the status area shows any problems. The following figure shows the result of uploading the APS-Model-Files directory. It shows a progress bar in blue at 100%. Files other than icd model files are ignored and a warning is displayed (in case the file name was misspelled).</li>
+</ol>
+<p><img src="../images/webapp/uploadFiles3.png" /></p>
+<ol>
+  <li>That&rsquo;s all for uploading. This can be done over and over and nothing is permanent until the API is published.</li>
+</ol>
+<h2><a href="#view-a-subsystem-api" name="view-a-subsystem-api" class="anchor"><span class="anchor-link"></span></a>View a Subsystem API</h2>
+<p>The next example shows how to view a subsystem API.</p>
+<ol>
+  <li>
+  <p>With the subsystem uploaded, its API can be viewed in the browser by selecting the subsystem in the subsystem pull-down menu at the top of the screen. The menu shows all the subsystems found in the local database.</p></li>
+  <li>
+  <p>The browser content area will redraw with the contents of the selected subsystem. The result of selecting APS is shown in the following figure.</p></li>
+</ol>
+<p><img src="../images/webapp/apsApi.png" /></p>
+<p>A couple of things to note: The area to the left shows a number of links. This area has one link for each component in the subsystem.</p>
+<p>The content area displays all the components for the subsystem. Clicking on one of the component links jumps to the given component’s information.</p>
+<p>The displayed API is constructed from the current versions of the models in the database, and is therefore considered an unpublished working version. Although APIs are published by Systems Engineering, the system allows the viewing of all versions of published APIs as well as the working version as shown above (Note: the published versions of the APIs are ingested directly from the GitHub repository, whereas the unpublished models are obtained only from the local database). To do this, select the desired version number in the dropdown menu next to the subsystem name.</p>
+<p>Note that “master” also appears in the list of versions and is linked to the contents of the master branch of a subsystem on GitHub. The contents of the master branch are automatically uploaded to the icd database (if there was a change) whenever you refresh the web app or when running the command: <code>icd-git --ingestMissing</code>.</p>
+<p><img src="../images/webapp/tcsSelectVersion.png" /></p>
+<p>There are two checkboxes in the Select dialog that are only enabled for APIs (when only one subsystem is selected).</p>
+<ul>
+  <li>Include client API information (subscribed events, sent commands)</li>
+  <li>Search all TMT subsystems for API dependencies</li>
+</ul>
+<p>Selecting the first checkbox will include sections for subscribed events and sent commands in the API document, as well as columns for subscribers of published events and senders of received commands. By default, these are not displayed in API documents.</p>
+<p>Selecting the second checkbox will enable searching the entire database for subscribers of published commands and senders of received commands. By default, only the selected subsystem is searched for this information. </p>
+<h2><a href="#check-for-missing-items" name="check-for-missing-items" class="anchor"><span class="anchor-link"></span></a>Check for Missing Items</h2>
+<p>A recent addition to the icd web app is the Missing button that generates a PDF report displaying subscribed events that have no known publisher, or sent commands that are not defined anywhere or component names that refer to nonexisting components.</p>
+<p><img src="../images/webapp/missingButton.png" /></p>
+<p>The Missing report is based on the selected subsystem or subsystems. If no subsystem is selected, it reports on all subsystems. If two subsystems are selected (an ICD), the report only lists the missing items directly related to the two subsystems. If you select a single subsystem, the report will list all references that it makes to undefined items (commands, events, components).</p>
+<p><img src="../images/webapp/missingReport.png" /></p>
+<p>It is a good ideas to view this report before publishing a subsystem API to find invalid references.</p>
+<h2><a href="#generate-source-code-from-the-icd-database" name="generate-source-code-from-the-icd-database" class="anchor"><span class="anchor-link"></span></a>Generate Source Code from the ICD Database</h2>
+<p>The Generate button lists the languages for which you can generate source code from the ICD database: Scala, Java, Python and TypeScript.</p>
+<p>First select a subsystem and, optionally, a version and component. Then select Generate → Scala, for example. The generated source code containing event and command names and keys for the selected subsystem and component(s) is downloaded automatically to a file named *Subsystem*Api.scala in your Downloads directory: For example: TcsApi.scala. The keys can be found in nested objects (namespaces or static classes) starting with the top level object.</p>
+<p><img src="../images/webapp/generateButton.png" /></p>
+<h2><a href="#view-api-history" name="view-api-history" class="anchor"><span class="anchor-link"></span></a>View API History</h2>
+<p>The history of every published API can also be viewed, including an entry for every time the API is published. Selecting two different version checkboxes enables the Compare button, which shows the changes made between the versions in a JSON based format. Note that you can also compare versions of released APIs on GitHub under <a href="https://github.com/tmt-icd">https://github.com/tmt-icd</a>, since a version tag is added for each published version. There are also tools for comparing PDF files, which might be useful.</p>
+<p>To view the API history, select a subsystem, and press the History button. The content area changes as shown in the following:</p>
+<p><img src="../images/webapp/history.png" /></p>
+<h2><a href="#create-and-view-an-icd" name="create-and-view-an-icd" class="anchor"><span class="anchor-link"></span></a>Create and View an ICD</h2>
+<p>An ICD is formed by taking the intersection of the APIs of two TMT subsystems. That means in order to create an ICD there must be at least two subsystems in the database. The TCS API is created from various subsystem to TCS ICDs that exist and the TCS CODR SDD. The definitive TCS API will be a product of the TCS work packages.</p>
+<p>It is possible to view ICDs with working/unpublished versions, with one unpublished version and one published version, or two published versions. ICDs can only be published between two published APIs.</p>
+<p>This example will show how to view a working ICD between the published version 1.12 of the TCS API and the unpublished M1CS subsystem API.</p>
+<ol>
+  <li>
+  <p>Upload all the working versions of the APIs needed to form an ICD.</p></li>
+  <li>
+  <p>First select the version of the subsystem for the ICD. In the figure below the menu to the right of the subsystem shows the available versions. Version 1.12, the version published previously is selected. (To get back to the working version, select the asterisk in the menu.) Note that the content area says API for TCS 1.12 rather than the unpublished label.</p></li>
+</ol>
+<p><img src="../images/webapp/select-tcs-m1cs-icd.png" /></p>
+<ol>
+  <li>Next, select a second subsystem in the second subsystem menu as shown in the figure to below the Subsystem menu. The figure shows the available subsystems (some may be only local and others automatically ingested from the ICD GitHub repositories). TCS is also selectable since one subsystem component can have an ICD with another in the same subsystem. Selecting M1CS shows the following screenshot (without the red arrow). To get out of ICD mode and back to browsing APIs, select the top item (Select Subsystem) in the second subsystem menu on the Select tab.</li>
+</ol>
+<p><img src="../images/webapp/tcs-m1cs-icd.png" /></p>
+<p>Note that the title shows ICD from TCS to M1CS (unpublished). This means that the displayed ICD is not published by Systems Engineering — it is a draft version.</p>
+<p>Also note the circle on the screenshot below. The section “Events published by GLC” shows items published by the GLC component. The Subscriber column is a link to the component that subscribes to the event stream. The link can be selected to jump to the subscribing component, regardless of which of the two subsystems it is in.</p>
+<p><img src="../images/webapp/glc-events-published.png" /></p>
+<p>The same is true for commands: There are links to the command senders for received commands.</p>
+<p><img src="../images/webapp/glc-commands-received.png" /></p>
+<p>The ability to see and display these links is one of the highest priority features for this project. This is one feature that is not possible with simpler documentation tools.</p>
+<h2><a href="#view-icd-history" name="view-icd-history" class="anchor"><span class="anchor-link"></span></a>View ICD History</h2>
+<p>Like an API, it’s possible to view the history of an ICD between two subsystems.</p>
+<ol>
+  <li>With a published ICD is selected, select the History button as was done in the about viewing an API history. The following screenshot shows the history for the IRIS to TCS ICD. The versions of the APIs are shown as well as the ICD version.</li>
+</ol>
+<p><img src="../images/webapp/icd-hist.png" /></p>
+<h2><a href="#print-an-icd-or-api" name="print-an-icd-or-api" class="anchor"><span class="anchor-link"></span></a>Print an ICD or API</h2>
+<p>The last supported feature is to print an API document or save it as a PDF for inclusion as a review deliverable. Ideally, we will just provide a link to the IDBS that reproduces the referenced ICD, but the PDF option in the toolbar allows outputting a PDF version with a table of contents and front page. The figure below shows a portion of the PDF output for our TCS to M1CS ICD Version 1.1.</p>
+<p><img src="../images/webapp/icd-m1cs-tcs.png" /></p>
+<h2><a href="#view-a-graph-of-component-relationships" name="view-a-graph-of-component-relationships" class="anchor"><span class="anchor-link"></span></a>View a Graph of Component Relationships</h2>
+<p>The Graph button in the Select tab displays a dialog for creating a graph of component and subsystem relationships. The graph is based on the selected subsystems and components, which we call the primary components. These are displayed as solid ovals. All the components that the primary components talk (via events or commands) to are then included as dashed ovals. The edges of the graph indicate the flow of events and commands between the components. References to events or commands that were never defined are displayed in red, as are components that do not exist.</p>
+<p>The figure below shows the Select dialog with the Graph toolbar button and the IRIS.oiwfs.poa component selected:</p>
+<p><img src="../images/webapp/graph-select-iris.png" /></p>
+<p>Pressing the Graph button opens a dialog with options for the graph:</p>
+<p><img src="../images/webapp/graph-pdf-options.png" /></p>
+<p>Note that the graph is created using the GraphViz Dot language. See <a href="https://graphviz.org/">https://graphviz.org/</a> for an explanation of layouts and overlap handling. You can also use the <code>icd-viz</code> command line application to produce the same graph. The command line version lets you choose more than two primary components and save the Dot file.</p>
+<p>Pressing Apply in the Graph dialog creates this graph for the selected IRIS component:</p>
+<p><img src="../images/webapp/graph.png" /></p>
+<p>The default colors used for the graph can be found in the <code>icd-viz</code> <code>reference.conf</code> file and can also be overridden with a command line option like <code>-Dicd.viz.color.IRIS=darkgreen</code> (Replace IRIS with the subsystem and the color with a valid Graphviz color). A future version of the icd web app may include a tab in the graph options dialog for configuring the colors.</p>
+<p>Here is a legend for the generated graph:</p>
+<p><img src="../images/webapp/legend.png" /></p>
+<p>In the above graph, you can see that <code>oiwfs.poa</code> is the primary component (represented as a solid oval). It publishes events to other components, such as <code>IRIS.oiwfs.detector</code> and <code>AOESW.aosq</code> and subscribes to events from <code>NFIRAOS.rtc</code> and <code>TCS.cmIRIS</code>. <code>AOESW.aosq</code> also sends commands to <code>oiwfs.poa</code>, however the command names are not listed, since that option was not selected in the graph dialog. The red question mark in IRIS indicates that <code>oiwfs.poa</code> publishes events that have no known subscribers. The other red arrows indicate that it also subscribes to some events that are not published anywhere (perhaps an error). Displaying these errors is optional. The figure below shows the same graph with the missing events option turned off and command labels turned on.</p>
+<p><img src="../images/webapp/IRIS-graph-no-errors.png" /></p>

+<h1><a href="#idbs-workflow-and-creating-icds" name="idbs-workflow-and-creating-icds" class="anchor"><span class="anchor-link"></span></a>IDBS Workflow and Creating ICDs</h1>
+<p>This section describes how the IDBS fits into the software development process at TMT. This workflow is shown in the context of the TMT Software Quality Assurance Plan and Software Development Process (SQUAP and SDP) [RD01], which describes the entire software development process.</p>
+<p>OMOA components consist of HCDs, Assemblies, Sequencers, and Applications. The components are developed incrementally and independently of other subsystem’s components.</p>
+<p>Each component has a <em>public interface</em> or <em>application programming interface</em> (API). The API is based on the services provided by common software. The API shows all the available functionality of a component and subsystem.</p>
+<p>Each TIO software ICD consists of a <em>framework</em> part and a <em>detailed</em> part. The framework part is written in Word according to the TIO Systems Engineering template. The detailed part is generated from the ICD-DB and can change more frequently without requiring updates to the framework document - at least in the case where the framework information does not change.</p>
+<p>A component developer creates a set of model files for each component that describes the component and its interfaces (see the section on <a href="../modelFiles/modelFiles.html">model files</a>). These model files are text files. When the component interface changes, the developer updates the model files, validates them, and when ready, checks them into a dedicated repository for model files at the GitHub site: (<a href="https://github.com/tmt-icd)">https://github.com/tmt-icd)</a>.</p>
+<p>When working on or changing an interface used by another TIO subsystem that will be part of an ICD, the component developer should work with the other subsystem developers to determine the correct functionality and API.</p>
+<p>Once the model files are checked in, TIO Systems Engineering determines when the new version of a subsystem’s API can be published and given a new incremental version number. Systems Engineering will review any changes that impact other subsystems and ensure they are aware of and agree with changes that will be part of an ICD. New releases of the API documents can be published and will be seen as published in the ICD-DB web user interface.</p>
+<p>TIO Systems Engineering also determines when a new ICD can be generated based on the APIs of the constituent subsystems and manages the publication of a new detailed ICD release. When published, the new ICD is also shown as published in the ICD-DB web user interface.</p><div class="callout note "><div class="callout-title">Note</div>
+<p>It may be necessary to click the browser refresh button to see a newly published API or ICD that is not yet in the local icd database (The icd web app then automatically ingests any newly published APIs and ICDs into the local database). The command <code>icd-git –ingest</code> will also update the local database from the released versions on GitHub.</p></div>
