XMPP Extensions
The XMPP Standards Foundation (XSF) develops extensions to XMPP through a standards process centered around XMPP Extension Protocols (XEPs). The process is managed by the XMPP Extensions Editor and involves intensive discussion on the Standards mailing list, formal review and voting by the XMPP Council, and modification based on implementation experience and interoperability testing. All documents in the XEP series are available under a liberal IPR Policy for wide implementation. Submissions are welcome (see also the "inbox"). All XEPs and related files are under source control, old versions are available, and IETF-style XML reference files are provided.
This page lists approved XMPP extensions as well as proposals that are under active consideration. A list of all XEPs (including retracted, rejected, deprecated, and obsolete XEPs) is also available. Good places for developers to start are the basic client, basic server, intermediate client, and intermediate server protocol suites.
Note: The following table is sortable, just click on the headers (click twice to reverse the sort order).
