<section1 topic='Introduction' anchor='intro'>
<p>The Jabber protocols have long included a method for discovering version information about the software running at another entity's JID. This method makes use of the 'jabber:iq:version' namespace and has been documented variously in Internet-Drafts and elsewhere. Because this protocol is not required by &rfc2779;, the 'jabber:iq:version' namespace was removed from &xmppim;. This specification fills the void for canonical documentation.</p>
<p><em>Note Well: The jabber:iq:version protocol SHOULD NOT be used to determine the identity of entities from which an application receives presence (e.g., contacts in a user's roster and certain kinds of gateways); &xep0115; SHOULD be used instead. However, the jabber:iq:version protocol MAY be used to determine the identity of entities from which an application does not receive presence (e.g., servers and many kinds of components). The jabber:iq:version protocol MAY also be used to determine information available only via jabber:iq:version (e.g., operating system information) for contacts from which a user receives presence, but only if the user specifically requests such information.</em></p>

<p>The 'jabber:iq:version' namespace provides a standard way for Jabber entities to exchange information about the software version used by the entities. The information is communicated in a request/response pair using an &lt;iq/&gt; element that contains a &lt;query/&gt; scoped by the 'jabber:iq:version' namespace. The following children of the &lt;query/&gt; are allowed in an IQ result:</p>
