<p>The ability to discover information about entities on the Jabber network is extremely valuable. Such information might include features offered or protocols supported by the entity, the entity's type or identity, and additional entities that are associated with the original entity in some way (often thought of as "children" of the "parent" entity). While mechanisms for doing so are not defined in &xmppcore;, several protocols have been used in the past within the Jabber community for service discovery, specifically &jep0011; and &jep0094;.

<li><p>Neither Jabber Browsing nor Agent Information is easily extensible. For example, the categories and subcategories listed for JID-Types in JEP-0011 are explicitly defined as the only official categories, and any additions to the list of JID-Types would require a modification to JEP-0011. While the Jabber Browsing specification does allow for the use of unofficial categories and types prefixed with the string 'x-', this introduces migration issues. This lack of flexibility violates one of the Jabber community's core &jep0134;.</p></li>

<li><p>In Agent Information, there is no way to advertise supported features. While Jabber Browsing includes such a mechanism, the only way to express the availability of a feature is to advertise a supported protocol namespace. Yet some features may not be uniquely associated with a protocol namespace, which are one implementation of features but not the only one.</p></li>
<li><p>A Jabber Browsing result returns a combination of (1) namespaces supported by a Jabber Entity, (2) items associated with a Jabber Entity, and (3) namespaces supported by the associated items. This approach mixes information levels and requires parents to know everything about child nodes, thereby introducing significant confusion.</p></li>
<li><p>In both Jabber Browsing and Agent Information, items must be addressable as JIDs; however, this may not be possible in some applications.</p></li>
</ol>
<p>This JEP addresses the perceived weaknesses of both the Jabber Browsing and Agent Information protocols. The result is a standards-track protocol for service discovery (often abbreviated to "disco", as is familiar in protocols such as &w3soap;).</p>

<section2 topic='Items Nodes' anchor='items-nodes'>
<p>It is possible that an item associated with an entity will not be addressable as a JID; examples might include offline messages stored in an inbox (see &jep0013;), entries in a Jabber-enabled weblog, XML-RPC services associated with a client or component, items available in an online trading system (e.g., a catalog or auction), news postings located at an NNTP gateway, and topics hosted by a &jep0060; component. In order to handle such items, the &lt;item/&gt; element MAY possess an OPTIONAL 'node' attribute that supplements the REQUIRED 'jid' attribute.</p>

In order to handle such items, the &lt;item/&gt; element MAY possess an OPTIONAL 'node' attribute that supplements the REQUIRED 'jid' attribute.</p>
<p>The value of the node attribute may or may not have semantic meaning; from the perspective of Service Discovery, a node is merely something that is associated with an entity. In order to discover more about the node, the requesting entity MUST query the entity's JID while specifying the node. If the value of the 'node' attribute has semantic meaning, that meaning is provided by the using protocol or application, not by the Service Discovery protocol. A node attribute SHOULD NOT be included unless it is necessary to provide or discover information about an entity that cannot be directly addressed as a JID (i.e., if the associated item can be addressed as a JID, do not include a node). The value of the 'node' attribute MUST NOT be null.</p>
<p>In the following example, a user requests all available items from an online catalog service:</p>

</ol>
<p>In addition, the results MAY also be mixed, so that a query to a JID or a JID+node could yield both (1) items that are addressed as JIDs and (2) items that are addressed as JID+node combinations.</p>

<section1 topic='Publishing Available Items' anchor='publish'>
<p>The server handling rules defined in <strong>XMPP IM</strong> require that the server itself reply on behalf of the user if the 'to' attribute of an IQ get or set is of the form &lt;user@host&gt;. This functionality is currently employed so that the user can "publish" information (e.g., vCard information as specified in &jep0054;) in a way that makes it possible for other entities to retrieve that information even if the user is unavailable. The service discovery specification defined herein builds on that notion by enabling a user to publish some of its service discovery information to the server, which shall store that information in persistent storage and return that information when other entities request it from the user's "bare JID" (user@host), either alone or in combination with a particular node.</p>

<p>Implementations of service discovery that are built into instant messaging servers SHOULD allow users to publish items in this fashion, although they are not required to do so in order to conform to the service discovery specification.

<p>In order to retrieve full information about an entity and its associated items, the requesting application needs to "walk the tree" of items. Naturally, this can result in a large number of requests and responses. The requesting application SHOULD NOT send follow-up requests to all items associated with an entity if the list of such items is long (e.g., more than twenty items). Entities that will routinely host a large number of items (e.g., IRC gateways or NNTP services) SHOULD structure nodes into hierarchies and/or provide more robust searching capabilities, for example via &jep0055;; they SHOULD NOT return extremely large result sets via Service Discovery.</p>
<p>This JEP does not require that a responding entity must return the same results in response to the same request from different requesting entities (e.g., an entity could return a different list of items or features based on the degree to which it trusts the requesting entity, or based on the known capabilities of the requesting entity). However, the responding entity SHOULD return the same &lt;identity/&gt; element (category+type) to all disco#info requests sent to the same JID+node combination.</p>

<p>It is widely acknowledged that it would be good to be able to express a Jabber Identifier (JID) (see &xep0029;) as a Uniform Resource Identifier (see &rfc3986;). In addition, there would be value in being able to interact with a JID through a URI scheme (e.g., by sending a message or a presence update).</p>
<p>Although XMPP enables a wide range of functionality, the authors propose that a Jabber URI scheme needs to support only a limited subset of the possible Jabber functionality. In particular, we see the following as core functions that need to be supported:</p>

<p>The syntactic components of a Jabber URI are as follows:</p>
<code>&lt;xmpp&gt;:[&lt;node-identifier&gt;@]&lt;domain-identifier&gt;[?&lt;query&gt;]</code>
<p>This scheme is similar to the mailto URI scheme <note>The mailto URI scheme is described in RFC 2368: <link url='http://www.ietf.org/rfc/rfc2368.txt'>http://www.ietf.org/rfc/rfc2368.txt</link>.</note>. One similarity is that a Jabber URI is, in the terminology of RFC 3986, not hierarchical but opaque. A URI that is hierarchical in nature uses the slash ("/") character in order to separate hierarchical components, as is familiar from HTTP and FTP URIs. By contrast, an opaque URI such as a mailto URI contains only the scheme (e.g., 'mailto'), a colon, an address (e.g., 'user@host'), and an optional query component.</p>
<p>Per the JID definition in JEP-0029, the node identifier is optional (i.e., a mere domain identifier is a valid JID). However, the proposed Jabber URI scheme forbids the inclusion of a resource identifier in the JID, even though JEP-0029 defines this as valid. This is partly because the authors see no compelling reason to include a resource identifier in the Jabber URI scheme, and also because including a resource would necessitate the inclusion of a slash character in an opaque URI, which is contrary to RFC 3986. Finally, the query component is optional.</p>

<section1 topic='URI Characters and Escape Sequences'>
<p>RFC 3986 limits the characters included in a URI to US-ASCII characters, and further defines a number of US-ASCII characters as reserved or otherwise excluded. Reserved characters are special characters used as delimiters withing URIs and whose usage is limited to their reserved purpose as defined in RFC 3986 or a specific URI scheme. Excluded characters are control characters, spaces, and other common (non-URI-specific) delimiters such as angle brackets, double quotes, the number sign, and the percent sign. Reserved characters must be escaped if their usage in a specific context would conflict with their reserved purpose, and excluded characters must always be escaped. The set of disallowed charaacters for any specific URI component consists of the reserved and excluded characters for that component. These are defined below for each component of a Jabber URI.</p>

<p>On the existing Jabber network, there are many opportunities to optimize stanza traffic.

<p>Furthermore, there exists the potential for abuse related to the 'replyto' and 'replyroom' features (e.g., an entity could send messages with 'replyroom' set to the address of a room that hosts salacious content or with 'replyto' set to the address of a spambot that harvests Jabber addresses). Therefore if a human user's receiving application receives a message with extended stanza addressing that specifies a 'replyto' or 'replyroom' address other than that of the sender, it SHOULD inform the user of that fact.

Icon styles may be traded and shared among users of all supporting clients like skins or themes, similar to WinAmp, XMMS, GNOME, and other customizable applications. This creates a platform-independent system, providing a great degree of customization for the user, and allowing client developers to focus on other features.</p>

and lists in general are really the province of disco and browse and
that at least one of the suggested 'core' statistics doesn't
make sense for all components so removed these from the JEP. This namespace

<p>As things currently stand it is not possible to obtain statistics
from a jabber component or server without resorting to parsing the
various log files. This makes it extremely difficult to obtain statistics

rectify this situation by defining a new namespace that would be used
