Feature Request

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 xmpp:microblog:0 as a common choice to manage news for client accounts (e.g. blog@getpelican.com), yet a component account (e.g. pubsub.getpelican.com) may use all of its nodes for this purpose.

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

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

I have made a script using the slixmpp library 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. PubSub Over HTTP

I am willing to assist to add this feature.

I beg your pardon. Please move this to getpelican/pelican-plugins/issues

That would be really cool. Especially if a comment section could be done that way too.

Nodes

Yes, comments can also be managed in a similar manner.

Perhaps XEP-0248 PubSub Collection Nodes would be useful for comments, though it might not be necessary.

Publishings node
|- Item (ID: 0001)
  |- Atom entry (HTML inside)
|- Item (ID: 0002)
|- Item (ID: 0003)
|- etc.

Comments node
|- Item (ID: 0001)
  |- Comment
  |- Comment
  |- Comment
  |- Comment
|- Item (ID: 0002)
  |- Comment
  |- Comment
  |- Comment
|- Item (ID: 0003)
  |- Comment
  |- Comment
|- etc.

We can allocate them by nodes

node	access	note
publishings.getpelican.com	public	HTML as Atom feed is stored
comments.getpelican.com	public	where we manage comments
sources.getpelican.com	admins	Markdown / reStructuredText
attachments.getpelican.com	?	This can be done too

XMPP Clients

In what fashion did you think to handle comments?

I suppose we can synchronize comments from HTTP and from XMPP.

For comments via XMPP, we might want XMPP clients (like Movim and Libervia) to handle.

Other clients: Once Pelican has PubSub support, it would be easy to persuade Dino, Cheogram, Converse, Gajim, Kaindan, monocles, Psi etc. to allow PubSub for comments and reactions.

More Information

We have a good discussion at Chyrp Lite (PHP CMS)
xenocrat/chyrp-lite#250

I have also made a proposal for scheme for managing CMS in node
movim/movim#1312

Please be aware of the following implementations.

Reading from PubSub

See code at: codeberg.org

Sending to PubSub

See function xmpp_pubsub_send_unread_items at gitgud.io (it is function which calls to other functions that return node, item and send the result).

I am willing to handle the XMPP code for you if you want.

This is way over my head, I just happen to host my own Pelican and XMPP server and would really like to see an XMPP renaissance. Unfortunately, other than with licensing, I don’t think I can help much here. Would love to see how it all plays together though!

To make things even more connected, Libervia has some code to bridge XMPP PubSub with ActivityPub:
