UPDATED: XEP-0421 (Occupant identifiers for semi-anonymous MUCs)

by Daniel Gultsch

Version 0.3.0 of XEP-0421 (Occupant identifiers for semi-anonymous MUCs) has been released. Abstract: This specification defines a method that allows clients to identify a MUC participant across reconnects and renames. It thus prevents impersonification of semi-anonymous users. Changelog: * Adjust wording to use semi-anonymous or pseudonymous instead of anonymous * Explicitly mention issues arising from occupant id matching across rooms * Add example with server secret instead of room secret * Add some pseudocode (lmw) URL: https://xmpp.org/extensions/xep-0421.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent. The XEP documents linked herein are up-to- date.

[XEP-0284] Shared XML Editing revival

by Goffi

Hello, I'm very interested in XEP-0284, and there is this PR from Link Mauve buried for years to revive it: https://github.com/xsf/xeps/pull/904 I would like to put that on council agenda, but I have the following question: - are the previous author still unreachable? I'll put their address as recipients of this email. - Peter Saint-Andre is still around as the XSF Treasurer. So Peter could you tell us if you agree with this PR and with Link Mauve taking over the XEP? - Link Mauve, are you still OK with this PR and being an author of this specification? If all 3 above give green lights, Daniel would you mind adding this to Coucil agenda? Thank you all! Best, Goffi

Blasta, Libervia, and Movim

by Schimon Jehudah

Good day. I would want your advise concerning project Blasta, an annotation system based on XMPP. The project Blasta https://blasta.woodpeckersnest.eu/ is utilizing the specification Atom Over XMPP, and has insentivise me to think of a new XEP that be similar to XEP-0277 (Libervia) and XEP-0472 (Movim), which is the same without the content field. Yet the discussion to standartize bookmark structure at the buku project https://github.com/jarun/buku/discussions/795 and the structure which is used by the linkding bookmark project https://demo.linkding.link/bookmarks which does include a content field with the markdown format, which is what Movim does, has led me to think of supporting the field "content" of Atom Syndication Format. Further, the publishing project Postmill https://postmill.xyz/ works very similarly to bookmarks and forum systems, so comments, which are part of XEP-0277 (Libervia) and XEP-0472 (Movim) are also valid. Hence, I think that Blasra needs to be compatible with XEP-0277 (Libervia) and XEP-0472 (Movim) albeit its main purpose is to manage bookmarks. Please write your thoughts about this matter. Kind regards, Schimon

Encrypting PubSub node items

by Schimon Jehudah

Good day to one and all! I have been contemplating the idea of utilizing PubSub as a platform to synchronize browser bookmarks, history and tabs. See article "XMPP For Browsers" at The XMPP Newsletter of November 2024. I have received crucial criticism by the Pale Moon developers due to neglegence of encryption. It is not in my intention to neglegence encryption, yet I do not intend to add encryption before a working prototype. Schimon: > > There is no storage encryption yet. I do not know whether it is > > necessary Moonchild: > Unacceptable. > Nobody but the end user should be able to access the stored data. > Encryption is required, and encryption should be set up in such a way > that nobody aside from the end user (not even the server admin) has > access to this data. Storing everything in plaintext in an XMPP > service instance is ridiculous. That said, the owner of the server must not have any access to the data. However, I am thinking of encrypting the data, yet I do not how to implement such system which will be possible to decrypt only by the owner of the data, and I also do not know how to handle a situation in which an encryption key was lost.

Id risks

by Dave Cridland

Hi all, Further to the note in the LC thread on XEP-0424, I'd really like to have a document (XEP, probably) that answers these questions: What are the risks of choosing an stanza identifier that is not unique? Does this still matter if the stanza identifier is unique to the session? To the sending jid? To the bare jid of the sender? What about missing off the stanza id attribute entirely? What about MUC? PubSub? Etc? If people have opinions, write away, and I'll volunteer to collate these into a XEP (or, possibly, a patch against XEP-0359). My reasoning is that we seem to vaguely know things can get Bad, but I for one can't find where we've documented these Bad Things. I'd be delighted to be corrected, as ever. Dave.
