<section1 topic='Introduction'>
<p>For ease-of-use in a Jabber client, it is desirable to have a way to store shortcuts to various services and resources (such as conference rooms and webpages) as 'bookmarks' which can be displayed in the user's client. Several Jabber clients have already agreed on and implemented a method to provide this service; that informal agreement is documented and expanded upon in this document.</p>
<p>&xep0049; provides us with a convenient method for storing user data on the server using jabber:iq:private; all we need to do is define a namespace and schema for storing this sort of information. To this end, we introduce the 'storage' element, and the 'storage:bookmarks' to handle this data.</p>

<p>For ease-of-use in a Jabber client, it is desirable to have a way to store shortcuts to various services and resources (such as conference rooms and web pages) as 'bookmarks' that can be displayed in the user's client. Several Jabber clients have already agreed on and implemented a method to provide this service; that informal agreement is documented and expanded upon in this document. In particular, we introduce the 'storage' element (qualified by the 'storage:bookmarks' namespace) as a container for this sort of this data. While the &lt;storage/&gt; element can be stored using any XML storage mechanism, this document describes two such methods that are specific to XMPP.</p>
</section1>
<section1 topic='The storage:bookmarks Namespace'>
<section1 topic='Data Format' anchor='format'>
<p>A storage element marked by the storage:bookmarks namespace will contain a collection of child elements, each representing a 'bookmark' to be displayed in the client. At present, only two sub-elements are defined, 'conference' for conference rooms and 'url' for normal URLs.</p>
<p>All elements under storage MUST allow a 'name' tag, which is the friendly name by which they will be displayed in the client. If an element lacks a 'name' tag, the client SHOULD generate an appropriate substitution based on the other available data.</p>
<section2 topic='The url element'>
<section2 topic='The conference element' anchor='format-conference'>
<p>One of the most common uses of bookmarks will likely be to bookmark conference rooms on various Jabber servers. It is this aspect of the bookmark system which is used today by existing clients such as Exodus <note>Exodus, see &lt;<link url='http://exodus.jabberstudio.org/'>http://exodus.jabberstudio.org/</link>&gt;.</note> and Rival Messenger <note>Rival Messenger, see &lt;<link url='http://rival.chote.net'>http://rival.chote.net/</link>&gt;.</note>. In addition to the required 'jid' attribute, the conference element also possesses an 'autojoin' attribute, which determines whether or not the client should automatically join that conference room on login; this attribute is of type xs:boolean (see &w3xmlschema2;) and the default value is "false". &BOOLEANNOTE;</p>
<p>The conference element MAY also contain 'nick' and 'password' sub-elements; the XML character data from these elements should be used when joining the room from the bookmark. Password is, of course, important for joining potentially password-protected &xep0045; rooms.</p>
<example caption='An example of the conference element'><![CDATA[
<storage xmlns='storage:bookmarks'>
<conference name='Council of Oberon'
autojoin='true'
jid='council@conference.underhill.org'>
<nick>Puck</nick>
<password>titania</password>
</conference>
</storage>
]]></example>
<p>This bookmark would be displayed as 'Council of Oberon' and, if activated, would attempt to join the conference room 'council@conference.underhill.org' with nickname 'Puck' and password 'titania'. A bookmark set may contain any number of conference rooms.</p>
</section2>
<section2 topic='The url element' anchor='format-url'>
<p>URLs are fairly simple, as they only need to store a URL and a title, and the client then can simply launch the appropriate browser.</p>
<p>A URL element therefore only needs a 'url' tag in addition to the required 'name', like so:</p>

<p>Many modern IM clients offer functionality that enables users to make notes about items in their roster. This comes in handy if users don't have meaningful information in their vCard or if you need to remember additional things related to a roster item.</p>
<section1 topic='Introduction' anchor='intro'>
<p>Many modern IM clients offer functionality that enables a user to make notes about the contacts in their roster. This is helpful if such contacts do not have meaningful information in their vCard or if the user needs to remember additional information related to a roster item. To define such functionality, we specify a &lt;storage&gt; element (similar to that introduced in &xep0048;) and appropriate child elements, qualified by a new namespace of 'storage:rosternotes'. While the &lt;storage/&gt; element can be stored using any XML storage mechanism, this document describes two such methods that are specific to XMPP.</p>
</section1>
<p>This specification defines a protocol for storing annotations about a given set of entities. Its primary goal is to enable users to store some personal piece of information with their roster items. &xep0049; provides with a convenient method for storing user data on the server using the 'jabber:iq:private' namespace; all we need to do is define a namespace and schema for storing this sort of information. For this the 'storage' element introduced in &xep0048; is reused, and a new namespace of 'storage:rosternotes' is added.</p>
<section1 topic='Data Format' anchor='format'>
<p>Annotations are stored using a &lt;storage/&gt; element qualified by the 'storage:rosternotes' namespace. This element contains a collection of one or more &lt;note/&gt; elements, each representing a note about a given entity. For any given JID there MUST NOT be more than one note.</p>
<p>The 'jid' attribute of the &lt;note/&gt; element SHOULD be used without a resource, i.e., it SHOULD be a bare JID (&BAREJID;) rather than a full JID (&FULLJID;). Along with the annotation a client MAY choose to store the creation time ('cdate') and modification time ('mdate') as attributes to the &lt;note/&gt; element containing the annotation; these attributes MUST conform to the DateTime profile specified in &xep0082; and the timezone SHOULD be UTC.</p>

<section1 topic='The storage:rosternotes Namespace' anchor='ns_storage_notes'>
<p>Annotations are stored using server-side private XML storage (the 'jabber:iq:private' namespace). A storage element marked by the storage:rosternotes namespace contains a collection of one or more &lt;note/&gt; elements, each representing a note about a given entity. For any given JID there MUST NOT be more than one note.</p>
<p>The 'jid' attribute of the &lt;note/&gt; element SHOULD be used without a resource. Along with the annotation a client MAY choose to store creation time ('cdate') and modification time ('mdate') as attributes to the &lt;note/&gt; element containing the note; these attributes MUST conform to the DateTime profile specified in &xep0082; and the timezone SHOULD be UTC.</p>
