XEP-0163 (Personal Eventing Protocol) Allow multiple publishers; XEP-0045 (Multi-User Chat) Allow PEP
by Schimon Jehudah 08 Dec '24

08 Dec '24

Good day! I am the developer of Slixfeed news bot, which is a syndication feed reader (Atom/RDF/RSS). This matter is also related to Morbot. See https://codeberg.org/TheCoffeMaker/Morbot/issues/13 Concern ------- I have to attempted experiment with PEP nodes, and my attempt has failed due to: XEP-0045 service-unavailable The feature requested is not supported by the conference XEP-0163 forbidden You're not allowed to create nodes Proposal -------- I suggest to enable PEP nodes for MUC JIDs too. I suggest to change the approach "One publisher per node.". See https://xmpp.org/extensions/xep-0163.html#approach-publisher > There is no need for multiple publishers to a PEP service, since by > definition the service generates information associated with only one > entity. The owner-publisher for every node is the bare JID of the > account owner. In order to allow a secondary "channel" interface for people and group chats, and also for other reasons (see further), it would be useful to: 1) Allow multiple publishers. 2) Allow PEP for MUC JIDs. By a "channel" interface, I mean, that should a news bot be included for a group chat, the updates would be sent to a PEP node of the group chat JID instead to the chat itself, which would keep the chat view cleaner. Example use cases: Number #3 represents the use of Morbot and Slixfeed, and is useful for forwarding of news journals. 1) Use : Inbox Affiliation : Publish-Only Publishers : JIDs which Presence is shared with or in Roster 2) Use : Collaboration (e.g. Pad, Whiteboard etc.) Affiliation : Publisher Publishers : Determined manually 3) Use : Updates Affiliation : Publish-Only Publishers : Determined manually Note ---- Slixfeed can use its own PEP nodes named after its subscribers respectively, albeit that would be more demanding on the server of which Slixfeed is operated on, than publishing to PEP nodes of other JIDs, and yet it would not be practical for group chat JIDs, which the bot also supports. Please advise. Kind regards, Schimon
