XMPP (RFC 6120), PubSub (XEP-0060) and Atom Over XMPP (RFC 4287)

[sjehuda]

Greetings!

My name is Schimon and I am a champion of Syndication and XMPP.

For those of you who are not famiiliar, XMPP (previously Jabber) is a messaging system with open standards. XMPP is extensible via XEP.

I will discuss about XEP-0060: Publish-Subscribe.

Almost a couple of decades ago, a discussion arose about incorporating Atom (RFC 4287) with XMPP PubSub, which is really easy because both are XML data.

One of the major benefits of utilizing PubSub is native Push Notifications (yes, that technique was much before HTML5) which do not require HTTP pulling.

That would be a great feature to have miniflux to utilize XMPP PubSub natively!

See a proof of concept I have made to parse PubSub nodes as Atom Syndication Format.

Cheers,
Schimon

Beside your proof of concept, are you aware of any public XMPP server that use Atom Over XMPP?

[sjehuda]

Yes, Movim.

Please login to https://mov.im/ with a Jaber ID (i.e. XMPP account) and visit https://mov.im/community/news.movim.eu where you would see a list of nodes that are "Atom Over XMPP".

The software responsible for populating these nodes is AtomToPubSub.

• https://github.com/edhelas/atomtopubsub
• https://github.com/imattau/atomtopubsub

Legend:

• https://mov.im/node/news.movim.eu/PlanetJabber
• https://mov.im/node/news.movim.eu/Phoronix
  news.movim.eu is a PubSub service.
  PlanetJabber and Phoronix are nodes.

The proof of concept script has been developed into an HTTP gateway.
I encourage you to view the video demonstration (length 7:44).
