XEP-0424 - Message retractation / MAM message deletion

[mremond]

XEP-0313: Message Archive Management does not propose a way to delete a message.

It would be handy to propose a draft XEP and implementation to handle server-side message deletion from archive.

Things to take into account:

• Do we want to delete from only my archive or all archives ?
• What should be the link with XEP-0424: Message Retraction ?
• What should be the link with XEP-0425: Message Moderation ?
• Specific handling and right management in the case of MUC.

Let's discuss here draft protocol and implementation.

I think such a draft should also support deletion of HTTP-uploaded resources when deleting a message that references an uploaded file. The problem with supporting this cleanly is that the actual referencing of uploaded files is done quite ad-hoc: The message typically just holds the URI to an uploaded file in the (possibly encrypted) body and in an OOB-URL. Nevertheless, if we support message deletion without upload deletion, it will take no longer than 48 hours until people complain 😄

+1 this would make perfect sense in modern messaging applications

This Link is a draft from 2015. might give a direction towards implementing it as well.

Once a draft is intact, can we expect it to be in the next versions?

Any progress on this?

I guess you can get inspiration from MongooseIM: esl/MongooseIM#2739

I can confirm that Message Retraction is working and is deleting messages from MAM. I did an integration in my app and the row with the message was deleted from the database.

Still I think it is not being advertised to disco#info as required by XEP-0424. It should advertise urn:xmpp:message-retract:1 as:

<iq type='result'
    to='[email protected]/orchard'
    from='[email protected]/balcony'
    id='info1'>
  <query xmlns='http://jabber.org/protocol/disco#info'>
...
    <feature var='urn:xmpp:message-retract:1'/>
...
  </query>
</iq>

But I'm not seeing it when I query for disco#info:

<iq xml:lang='en' to='...@.../...' from='...' type='result' id='...'>
