<section1 topic='Introduction' anchor='intro'>
|
|
<p>This document defines an extension mechanism for capturing "extended presence" data about user activities, above and beyond availability as defined in &xmppim; (e.g., the 'away', 'extended away', and 'dnd' values of the <show/> child of the <presence/> stanza).</p>
|
|
</section1>
|
|
<section1 topic='Protocol' anchor='proto'>
|
|
<section2 topic='Data Format' anchor='proto-format'>
|
|
<p>Information about user activities is provided by the user and propagated on the network by the user's client. The information is structured by means of an <activity/> element that is qualified by the 'http://jabber.org/protocol/activity' namespace. The general activity is provided as the element name of a first-level child of the <activity/> element (e.g., <relaxing/>); one such general activity element is REQUIRED. The general activity element MAY contain a child element that specifies a more particular form of the general activity (e.g., <partying/>). The user MAY also specify a natural-language description of the activity in the OPTIONAL <text/> child of the <activity/> element. Here is an example:</p>
|
|
<code><![CDATA[
|
|
<activity xmlns='http://jabber.org/protocol/activity'>
|
|
<relaxing>
|
|
<partying/>
|
|
</relaxing>
|
|
<text xml:lang='en'>My nurse's birthday!</text>
|
|
</activity>
|
|
]]></code>
|
|
<p>Instead of (but not in addition to) one of the specific activity elements defined herein, an application MAY include a properly-namespaced child element for the specific activity. Here is an example:</p>
|
|
<code><![CDATA[
|
|
<activity xmlns='http://jabber.org/protocol/activity'>
|
|
<relaxing>
|
|
<fishing xmlns='http://www.ilovefishing.info'/>
|
|
</relaxing>
|
|
</activity>
|
|
]]></code>
|
|
<p>Finally, one of the specific activity elements defined herein MAY itself contain a properly-namespaced child element that provides more detailed information about the specific activity. Here is an example:</p>
|
|
<code><![CDATA[
|
|
<activity xmlns='http://jabber.org/protocol/activity'>
|
|
<inactive>
|
|
<sleeping>
|
|
<hibernating xmlns='http://www.ursus.info/states'/>
|
|
</sleeping>
|
|
</inactive>
|
|
</activity>
|
|
]]></code>
|
|
<p>In accordance with &xmppcore;, the receiving application MUST ignore a specific activity element or detailed activity element if it does not understand the namespace that qualifies the element.</p>
|
|
</section2>
|
|
<section2 topic='Pubsub Transport' anchor='proto-pubsub'>
|
|
<p>The <activity/> element SHOULD be communicated by means of &xep0060;. Because activity information is not pure presence information and can change independently of the user's availability, it SHOULD NOT be provided as an extension to &PRESENCE;.</p>

<section1 topic='Activity Values' anchor='activities'>
|
|
<p>Each activity has a REQUIRED general category and an OPTIONAL specific instance. One can understand each specifier as '[user] is [activity]' (e.g., 'Juliet is partying'), where the relevant value is the most specific activity provided (e.g., specifically "partying" rather than generally "relaxing").</p>
|
|
<p>The activity values defined in this taxonomy are as follows, where the first indentation level is the general category and the second indentation level is the specific instance. Note: The specific activity elements are RECOMMENDED as forms of the general activities shown below, but can be included under any general activity (e.g., "gardening" could be used as the specific activity under "relaxing" rather than "doing_chores").</p>

<section1 topic='Mapping to RPID' anchor='rpid-mapping'>

<p>&rfc4480; defines several extensions to the &pidf; for so-called "rich presence". One such extension is the <activity/> element (see Section 4.2), which "describes what the presentity is currently doing". The following table shows a mapping from the defined RPID activity values to the Jabber values defined herein.</p>

<p>The XML character data values of the <text/> element are intended for presentation to human users; therefore, if a <text/> element is included the sending application SHOULD also ensure that the <text/> element or the parent <activity/> element possesses an 'xml:lang' attribute with an appropriate value.</p>
