<p>The <a href='/xsf/'>XMPP Standards Foundation</a> (XSF) develops extensions to <a href="/">XMPP</a> through a standards process centered around XMPP Extension Protocols (XEPs). The <a href="xep-0001.html">process</a> is managed by the <a href="editor.shtml">XMPP Extensions Editor</a> and involves intensive discussion on the <a href="http://mail.jabber.org/mailman/listinfo/standards/">Standards mailing list</a>, formal review and <a href="/council/votes.shtml">voting</a> by the <a href="/council/">XMPP Council</a>, and modification based on implementation experience and interoperability testing. All documents in the XEP series are available under a liberal <a href="ipr-policy.shtml">IPR Policy</a> for wide implementation. Submissions are <a href='submit.shtml'>welcome</a> (see also the <a href="/extensions/inbox/">"inbox"</a>). All XEPs and related files are under <a href="/xsf/sourcecontrol.shtml">source control</a>, <a href="/extensions/attic/">old versions</a> are available, and IETF-style <a href="/extensions/refs/">XML reference files</a> are provided.</p>
<p>This page lists approved XMPP extensions as well as proposals that are under active consideration. A <a href="all.shtml">list of all XEPs</a> (including retracted, rejected, deprecated, and obsolete XEPs) is also available. Good places for developers to start are the <a href='xep-0211.html'>basic client</a>, <a href='xep-0212.html'>basic server</a>, <a href='xep-0213.html'>intermediate client</a>, and <a href='xep-0216.html'>intermediate server</a> protocol suites.</p>
