[Standards] Re: Proposed XMPP Extension: XMPP Decentralized ID (XID)

Le mardi 2 juin 2026, 14:14:35 heure d’été d’Europe centrale Dave Cridland a écrit : Repleating my reply: Hi @dwd thanks for your feedbacks (very valuable, as always). - I've chosen `.internal` because it's reserved for private application use (https://en.wikipedia.org/wiki/.internal, https://www.rfc-editor.org/info/ rfc6762/#appendix-G) actually to avoid accidental reach of a real server. But you're right that on private networks it can be an issue. Your `xid.xmpp.org` proposal can be a solution. I would like to have more inputs on it before changing though. - The use of JID syntax is to make XID trivially usable in many use cases with little to no adaptation code (I'm thinking about "from"/"to" attribute with serverless, but in general anywhere were a JID is expected, a XID could be used). Please note the server mapping feature, and also in business rules, the example of "publisher" attribute for pubsub. We have also `xmpp:` URIs re- usable without any modification. - Your challenge comments are very relevant, I'll update after Council vote if the spec is accepted. - expiry would be nice indeed. Probably not mandatory though. - Multiple XIDs are already explicitly allowed, as well as having the same XID for various account on different domain names. - I'll have a look to what you suggest, but note that I try to make something simple and easy to implement. The first byte is there to extend algorithms easily later if necessary (for PQ or some other reason). One of the advantages of `Ed25519` is that it's already used with OMEMO, so most clients already have an implementation. I would like to avoid the discussion here if possible, and rather see it on standard@ (more eyes, no need to chase feedbacks everywhere, and archives are easier to retrieve). Best, Goffi
