This page gathers the different ways the MUC (XEP-0045) has been extended over the years, in the MUC document itself but not exactly defined or by additional documents. Some of this page may overlap with XEP-Remarks/XEP-0045:_Multi-User_Chat.

Multi-Session Nick

XEP-0045

If allowed by the service, a user can associate more than one full JID with the same occupant JID (e.g., the user juliet@capulet.lit is allowed to log in simultaneously as the nick "JuliC" in the characters@chat.shakespeare.lit chatroom from both juliet@capulet.lit/balcony and juliet@capulet.lit/chamber). Multi-session nicks are not currently defined in this document.

Invitations

XEP-0249: Direct MUC Invitations

XEP-0402: PEP Native Bookmarks

Defines a syntax and storage profile for keeping a list of chatroom bookmarks on the server

𐄂 XEP-0411: Bookmarks Conversion

Describes a method to migrate to PEP based bookmarks without losing compatibility with client that still use Private XML.

XEP-0469: Bookmark Pinning

Defines an XMPP protocol extension to allow users to pin PEP Native Bookmarks.

Identification

XEP-0421 Anonymous unique occupant identifiers for MUCs

Allows for actions to be associated to a unique identifier when the JID isn't visible.

Notifications

XEP-0437: Room Activity Indicators

Provides a mechanism for activity notifications in MUC

XEP-0452: MUC Mention Notifications

Allows a moderator to retract messages from other participants.

PubSub

XEP-0316: MUC Eventing Protocol

Defines semantics for using the XMPP publish-subscribe protocol to broadcast state change events associated with a Multi-User Chat (MUC) room. This profile of pubsub therefore enables a chatroom to function as a virtual pubsub service, easing the discovery of syndicated data and event notifications associated with such a room.

Optimisations

XEP-0410: MUC Self-Ping (Schrödinger's Chat)

Allows clients to check whether they are still joined to a chatroom.

XEP-0311: MUC Fast Reconnect
