Jabber/XMPP Protocol Namespaces

This is the official registry of Jabber/XMPP protocol namespaces as maintained by the XMPP Registrar. This registry contains only namespaces that are defined in the XMPP RFCs (published by the IETF) or in XMPP Extension Protocols that have advanced to a status of Active, Draft, or Final within the standards process of the XMPP Standards Foundation. Other namespaces may be in use within the Jabber/XMPP community, but are not added to this page until the relevant document meets the above criteria.
