Hi!

XMPP Spaces are now described in https://xmpp.org/extensions/xep-0503.html .

A XMPP Space is a Pubsub node that contains bookmarks pointing to MUCs.

We would like to have a proper Space URI that allow users to invite easily others to their Spaces. This will be added as a section to XEP 0503.

So far a Pubsub node is described in https://xmpp.org/extensions/xep-0060.html#impl-uri 

I'd like to have something short and transparent so I'm proposing something like this:

Proposal 1: xmpp:spaces.server.tld?;node=x56ae32&space

I'm wondering if something shorter like this is possible ? (where the client is resolving the "space" parameter as the Pubsub node)

Proposal 2: xmpp:spaces.server.tld?;space=x56ae32

The goals are

  • to prevent non "space-ready" XMPP clients to open it as a Pubsub node by mistake
  • have something  short and easily shareable (Discord is having something like this https://discord.gg/AP5HFj7w)

If one of the proposals is okay for you I'll propose a PR on 0503 and make the changes in Movim (I'm sure nicoco will be able to do it in Slidge, the other 0503 implementation).


We have a similar need to unambiguously reference FDP nodes in URIs, so if we can do something suitably generic here  - e.g. [node_uri]payload_type=(space|fdp), that would be tremendously useful to us too.
