XMPP: Post to PubSub

[sjehuda]

Short description of the enhancement

Greetings!

In XMPP, using PubSub(1) (XEP-0060), it is possible to store posts as Atom Syndication(2) entries into XMPP(3).

There are several XMPP extensions that apply it, namely XEP-0227 (4) and XEP-0472 (5) which make node urn:xmpp:microblog:0 as a common choice to manage news for client accounts (e.g. blog@processwire.com), yet a component account (e.g. pubsub.processwire.com) may use all of its nodes for this purpose.

pubsub.processwire.com/
|
|-- updates/
    |-- Sombre
     `-- Varied
|-- releases/
 `-- events/

pubsub service/
|
|-- node/
    |-- item
     `-- item
|-- node/
 `-- node/

A PHP library that can be utilized would be Moxl of Movim.

I have made a script that realizes viewing PubSub node items as Atom XML feeds over HTTP.

1. XEP-0060: Publish-Subscribe
2. RFC 4287: The Atom Syndication Format
3. Atom Over XMPP
4. XEP-0277: Microblogging over XMPP
5. XEP-0472: Pubsub Social Feed
6. Moxl or xmpp-php
7. PubSub Over HTTP

Current vs. suggested behavior

Forward/publish content to PubSub too.

Example:

pubsub.processwire.com/
|
|-- updates/
    |-- Sombre
     `-- Varied
|-- releases/
 `-- events/

pubsub service/
|
|-- node/
    |-- item
     `-- item
|-- node/
 `-- node/

Why would the enhancement be useful to users?

People who use XMPP, be able to view contents via XMPP, without the need to open an HTML/HTTP browser.

Optional: Screenshots/Links that demonstrate the enhancement

All contents on the Movim platform are stored on XMPP.
