XEP-0001 Changes to reflect current practice wrt XEP Authors

by Dave Cridland

Hey hey, Boring incoming: https://github.com/xsf/xeps/pull/1407 This is draft to avoid the XSF Board accidentally approving it before the community has had a chance to discuss. The main change is the paragraph added in Section 6 (Discussion Process), covering changes to the XEP during Experimental: The XEP author incorporates the feedback by creating source control patches > (such as Pull Requests), in line with the preferred method in &xep0143;. > Direct changes to an Experimental XEP, such as a contributor providing a > patch (or Pull Request on GitHub), are still the responsibility of the XEP > author, and are only applied if the XEP author agrees. If a XEP has > multiple authors, while agreement is sought from all authors, only those > opinions from responsive authors are considered. If the Approving Body > feels that the XEP author is not responsive, another author may be added > unilaterally by the Approving Body. This is trying to do two things: 1) Document the existing practice that the XMPP Council has followed, whereby changes to Experimental XEPs need "agreement" (PR approval, or similar) from the XEP Author. 2) Document the existing practice that the XMPP Council has followed. whereby if a XEP Author isn't responsive (ie, doesn't respond to emails, etc) the XMPP Council can add a new XEP Author. 3) Document the *new practice* that if a contribution isn't a PR, it's the XEP Author who is responsible to turn it into one. The rest of the changes surface and restate existing process/policy/URLs and aren't that interesting (well, even less interesting). There is one additional possible process deviation we should document (or call the Process Police out, or something). Submission of a XEP, as per XEP-0143, occurs via email tot he Editor. Is this really still the case? Or are these now by PR? That'll need changing in XEP-0143, which I'm happy to do if that's the case. It'd be nice to have a non-PR variant of the process (post here?)

Threads and replies in XMPP

by Goffi

Hello, We've got a discussion about thread on xsf@ a couple of days ago, and I would like to bring it here. I initially thought that XEP-0461 (Message Replies) was redundant with threads, except in the case where there is no thread ID in the message a user wants to reply too. After discussion, notably with singpolyma and lovetox, it appears that we don't have the same view on this. The way I got it, we have basically 2 ways to see threads: 1. A series of replies to any message in a group chat, à la Slack (in Slack, you see the replies hidden under parent message, with something like "X replies", and when you click, a panel appear with the whole thread. 2. A side discussion explicitly started, that could be seen like a new chat window (UI example: user clicks a "start a new thread button", and start a blank window with it message, this message has a new thread ID, that will be used by people replying to it). In case 1, the parent message needs a thread ID so that thread can continue with the same ID. Problem is if parent message doesn't has a thread ID (because client doesn't support thread, or because there is no thread ID for each message), in this case a XEP-0461 "reply to" can be used, then the first reply has a new thread ID, and the thread can continue. In case 2, the explicitly started thread has a newly generated thread ID, so there is no problem. I want to support both 1 and 2. For 1, my initial reading of XEP-0201 (Best Practices for Message Threads) was that a new thread ID should be generated for each message: > Unless a <message/> stanza is written in direct reply to another <message/> > stanza, if a ThreadID is included then its value SHOULD be newly generated > when a human user initiates a chat conversation with another user (i.e., a > <message/> stanza of type 'chat'), starts a new conversation in the context > of a multi-user chat environment (i.e., a <message/> stanza of type > 'groupchat'), or sends a normal message. XEP-0201 §3.2. But after discussion, I realise that it's not requested to generate a new ID each time, and it seems that generating new thread ID for each message would be a problem for some clients (notably Cheogram which would create a thread UI for each ID). The solution would be to use "reply to" from XEP-0461, then a newly generated thread ID. I've also proposed an alternative when parent message ID could be used as thread ID, this may we can find parent message without relying on XEP-0461. For the moment, I think that I won't generate new thread ID for each message, and if I create a thread from a parent message I'll use a XEP-0461 "reply to" and generate a new thread ID, then use this thread ID for following message in this thread. However, I would like to have feedback from the wider community: - how to you handle or plan to handle threads? - Are you planning to implement case 1 (threads can be started from any message) and/or case 2 (threads are explicitly started)? - How would you handle case 1? Thanks! Best, Goffi

A proposal to update XEP-0372: References

by Schimon Jehudah

Good day. Last week, I have contacted various of projects and asked to render messages with XMPP URI by their particular context. Please refer to the Gemini page or see the attached file for references. gemini://woodpeckersnest.space/~schapps/journal/2025-04-24-rendering-xmpp-uri-by-context.gmi After communicating this information to nephele, the developer of Renga chat client for Haiku, he has advised to standartize this approach by adding a new attribute to XEP-0372. Sun 27 Apr 2025 06:03:34 PM - nephele: > The XEP 0372 as it exists now seems to almost hit what you want, maybe > only another type is needed. for example <reference xmlns='urn:xmpp:reference:0' begin='72' end='78' type='adhoc' uri='xmpp:nephele@xmpp.org?command'/> Please advise. Kind regards, Schimon

XEP-0424/0425/0461: Spec misses guidance which ID should be used in case of corrections

by Philipp Hörist

Hi, All these XEPs miss a paragraph how corrections should be handled correctly e.g. if the ID of the original message or of the correction should be used. This leads already to different implementations in popular clients, none of which can be considered wrong as the XEPs do not specify a correct handling. Regards Philipp

URI Query Types for Ad-Hoc Commands and Data Forms

by Schimon Jehudah

Good day. I am the developer of Slixfeed news bot. Data Forms are extensively utilized by that bot. I think that it would be beneficial to define IRI/URI to acess to Ad-Hoc Commands and Data Forms. == Ad-Hoc Commands == This IRI/URI would open the form "manual". xmpp:slixfeed@xmpp.org?command=help This IRI/URI would open the form "about". xmpp:slixfeed@xmpp.org?command=about == Data Forms == Provided that a Data Form has an identifier, this IRI/URI would open the about dialog for the given query. This IRI/URI would open the form "about" (same as of the example of the Ad-Hoc Command, which can lead to the same form by explicitly define it). xmpp:slixfeed@xmpp.org?form=about-start This IRI/URI would open the form "about" in the next form to form about-start with the value "thanks". xmpp:slixfeed@xmpp.org?form=about-result?payload=thanks Please advise. Kind regards, Schimon
