UPDATED: XEP-0421 (Anonymous unique occupant identifiers for MUCs)

by Daniel Gultsch

Version 0.2.0 of XEP-0421 (Anonymous unique occupant identifiers for 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 anonymous users. Changelog: * Make explicit that one can't just hash the real JID. * Expand security considerations. * Add schema. * Fix some examples captions and casing (mw) 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.

XEP proposal: bookmark pinning for user chats

by avidseeker7＠protonmail.com

"XEP-0469: Bookmark Pinning" specifies the implementation for bookmark pinning but only for group chats? Not sure if there is already an existing XEP for that, but one for pinning user chats would be useful.

Send-only role

by avidseeker7＠protonmail.com

I am an end-user, and having used Telegram for some time, it offers a more fine-grained control over members of a group. One of those controls is to prevent group members (usually bots) from reading group messages, and only allow them to send messages, following the principle of least privilege. A more complex set up would be partially allow them to read messages directed to them and exclude the rest of messages. E.g: by specifying a command like /bot, the bot can read the content of that message to process it then reply back.

XEP-0424/425 Feedback

by Philipp Hörist

Hi, Some feedback while trying to implement these XEPs XEP-0424 1) The schema mentions <xs:attribute name='by' type='xs:string' use='optional'/> But the XEP does not mention the attribute, what is the purpose? 2) > When replacing the original message with a tombstone, the original contents (i.e. the <body/> and any related elements which might leak information about the original message) get replaced with a <retracted/> element which MUST include an 'id' attribute referring to the original message Why does the element MUST have an id attribute? its a element inside the <message> which already has the id, or in case of groupchat its inside a mam wrapper which has a stanza id, in all cases its perfectly clear that the retracted element belongs to the actual message wrapping it, maybe im missing something obvious here but i dont see a need for this id attribute at all. Example 7 > For messages of type 'groupchat', the stanza's Unique and Stable Stanza IDs (XEP-0359) <https://xmpp.org/extensions/xep-0359.html> [4 <https://xmpp.org/extensions/xep-0424.html#nt-idm41385450875712>] 'origin ID' MUST NOT be used for retractions Example mentions origin-id in groupchat context <message type="groupchat" from="romeo(a)montague.example" to="lord(a)capulet.example" id="wrong-recipient-1"> <retracted stamp='2019-09-20T23:09:32Z' xmlns='urn:xmpp:message-retract:1' id='origin-id-1'/> </message> XEP-0425 1) > A Message Archive Management (XEP-0313) <https://xmpp.org/extensions/xep-0313.html> [6 <https://xmpp.org/extensions/xep-0425.html#nt-idm34711750431632>] service MAY replace the contents of a message, that was retracted due to moderation, with a 'tombstone' similar to the one described in Message Retraction (XEP-0424) <https://xmpp.org/extensions/xep-0424.html> [5 <https://xmpp.org/extensions/xep-0425.html#nt-idm34711750445088>]. How similiar? The tombstone text does not mention seemingly important MUST rules from XEP 0424 For example > Some clients may have been offline while the retraction was issued. The archiving service therefore MUST store the retraction message, regardless of whether the original message is deleted or replaced with a tombstone. the above mentioned MUST rule about the id attribute in the <retracted> element, seems to be not important anymore in moderation, at least the id attribute is not found anymore in the tombstone. Im not saying we need to copy text 1:1 between the XEPs, but should the XEP not go into more detail what exactly the differences are, and what exactly from 0424 applies? Thanks Regards Philipp
