Hi all! With XEP-0469: Bookmark Pinning and XEP-0492: Chat notification settings we now have two XEPs that allow syncing pinning and notification settings across clients on the same account using the <extensions/> element of XEP-0402: PEP Native Bookmarks. Unfortunately, this now means that normal 1:1 chats (that are synchronized as roster items) lag behind. I'm volunteering to write a XEP adding an <extensions/> element alongside the <group/> element to allow arbitrary extensions for roster items. This would bring 1:1 roster items on-par with bookmarks2 and immediately allow XEP-0492 and XEP-0469 to be applied to roster items as well. But before I start I want to ask especially the server developers on this list: would you consider implementing this? If the answer is no or "some day far far in the future", it might be worth to try to invent some other mechanism that could be deployed faster. In my opinion, however, extending the roster items is by far the most elegant and simplest solution. What do you think? -tmolitor

Atom Activity Streams and Atom Over XMPP (XEP-0277 and XEP-0472)

by Schimon Jehudah

Good day. I have explored the "Atom Activity Streams" documents of Friendica. https://activitystrea.ms/specs/atom/1.0/ I have further added rendering capabilities to an RSS extension. https://greasyfork.org/scripts/465932-newspaper-syndication-feed-reader Proposal -------- Since Atom Activity Streams documents can be delivered as a single "atom:entry" element, as so with XMPP PubSub Node Items; then, it might be beneficial to mention "Atom Activity Streams" in the XEP specifications of Atom Over XMPP (XEP-0277 and XEP-0472). Rational -------- Even though, as it seems, an Atom Activity Streams document is, as with Atom Over XMPP, a single "atom:entry" element, with a couple of XML namespaces, this would stimulate people to: * Utilize XMPP PubSub Node Items in an independent fashion, without compiling an Atom Syndication Format document; and * Consider interoperability with Friendica and other platforms that produce Atom Activity Streams documents, and also Json Activity Streams documents, which Nostr utilizes. * Consider interoperability of projects with XMPP. * Motivate projects, such as Friendica to extend support of XMPP. XML Namespace ------------- The namespaces that are utilized by Friendica, and may be relevant, are: xmlns="http://www.w3.org/2005/Atom" xmlns:at="http://purl.org/atompub/tombstones/1.0" xmlns:activity="http://activitystrea.ms/spec/1.0/" xmlns:dfrn="http://purl.org/macgirvin/dfrn/1.0" xmlns:georss="http://www.georss.org/georss" xmlns:media="http://purl.org/syndication/atommedia" xmlns:ostatus="http://ostatus.org/schema/1.0" xmlns:poco="http://portablecontacts.net/spec/1.0" xmlns:statusnet="http://status.net/schema/api/1/" xmlns:thr="http://purl.org/syndication/thread/1.0" Sample ------ Herein attached an Atom Activity Streams document. Source: https://my-place.social/display/feed-item/107999490.atom https://my-place.social/display/1c9fc4fa-f51b9f6f654d0bd7-7c3a0251 https://piaille.fr/@movim/115519544289510132 Kind regards, Schimon

UPDATED: XEP-0060 (Publish-Subscribe)

by Daniel Gultsch

Version 1.30.0 of XEP-0060 (Publish-Subscribe) has been released. Abstract: This specification defines an XMPP protocol extension for generic publish-subscribe functionality. The protocol enables XMPP entities to create nodes (topics) at a pubsub service and publish information at those nodes; an event notification (with or without payload) is then broadcasted to all entities that have subscribed to the node. Pubsub therefore adheres to the classic Observer design pattern and can serve as the foundation for a wide variety of applications, including news feeds, content syndication, rich presence, geolocation, workflow systems, network management systems, and any other application that requires event notifications. Changelog: Describe the 'http://jabber.org/protocol/pubsub' disco#info feature. (gdk) URL: https://xmpp.org/extensions/xep-0060.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.

Navigation instructions for Atom Over XMPP (XEP-0277 and XEP-0472)

by Schimon Jehudah

Good day. About ===== I have recently suggested at project Movim to add navigational instructions to Atom entries (i.e. posts). I am still experimenting it, and it currently seems useful. Technicality ============ The idea is realized in a similar fashion to the classification of comments node with rel='replies' and title='comments'. https://xmpp.org/extensions/xep-0277.xml#comments Navigation ========== I advise to enable navigational instructions with rel='navigation' and title='previous' and title='proceed', and perhaps also title='index'. At the bottom of this page there are proceed or previous links to navigate and are generated from the instructions proposed above. https://journal.woodpeckersnest.eu/posts/2024-11-05-xmpp-as-the-internet/ Advantages ========== Navigational instructions would conveniently facilitate the creation of a CMS even over a single PEP node, without a compulsory need of having a PubSub service with multiple nodes to do so, by relating from post to post from within each posts. Navigational instructions would also incentivise the creation of articles that are segmented into parts of a series of posts, and portability thereof. Kind regards, Schimon

XEP-0440 No supported channel bindings

by Dave Cridland

Thilo, sorry! I had somehow missed that SASL2 mandates XEP-0440. It makes a lot of sense. But... Openfire currently doesn't support any channel bindings. It is sometimes used in cases where there is no TLS at all. This is quite deliberate and sensible in this case, please don't argue with this! This means there will always be cases where there are no channel bindings available (because there's no channel to bind to!). The schema doesn't include a minOccurs, and that means minOccurs='1' by default. This means at least one channel binding MUST be included. Is this intentional? I appreciate this is an oddball case (and I can support tls-server-endpoint for most normal cases), but is this the intent here or was the expectation that the minOccurs should be '0'? (I know tls-server-endpoint MUST be implemented, but MTI is not MTD etc). Dave.
