Islandora Handled Datastream Access

Introduction

Islandora handled datastream access allows view access to datastreams via the handle of the object.

Usage

This module adds the following URLs:

• /islandora/handled_access/handle/what/view With this URL a specific datastream can be viewed by using the handle, for example /islandora/handled_access/1887/12345/JPG/view will view the JPG datastream of the Islandora item with handle 1887/12345. If the TN datastream (thumbnail) is accessed and the islandora_imagecache is installed, the cached thumbnail will be used. As a special case, the what can be image: an JP2, JPG or MEDIUM_SIZE datastream (in that order) is then used if it exists, has an image mimetype (image/png, image/jpeg or image/jp2) and is accessible. Also, what can be document and then a document (PDF) or image or binary is returned. Also, what can be thumbnail and then the TN datastream is returned.
• /islandora/handled_access/handle/what/access This URL returns a JSON response that indicates if an item and datastream can be found based on the handle and if access is allowed. The special cases what are also possible.
• /access/handle/view This does the same as /islandora/handled_access/handle/what/view for what = document
• /access/handle/access This does the same as /islandora/handled_access/handle/what/access for what = document
• /access/handle/download This does the same as /islandora/handled_access/handle/what/view for what = document but downloads the document
• /access/handle/thumbnail This does the same as /islandora/handled_access/handle/what/view for what = thumbnail
• /access/PID/view Same as /access/handle/view but with a PID of an object.
• /access/PID/access Same as /access/handle/access but with a PID of an object.
• /access/PID/download Same as /access/handle/download but with a PID of an object.
• /access/PID/thumbnail Same as /access/handle/thumbnail but with a PID of an object.
