  <title>User Mood</title>
  <abstract>This specification defines a payload format for communicating information about user moods, such as whether a person is currently happy, sad, angy, or annoyed. The payload format is typically transported using the personal eventing protocol, a profile of XMPP publish-subscribe specified in XEP-0163.</abstract>

<section1 topic='Introduction' anchor='intro'>
  <p>This document defines an extension mechanism for capturing "extended presence" data about user moods.</p>
</section1>
<section1 topic='Protocol' anchor='proto'>
  <section2 topic='Data Format' anchor='proto-format'>
    <p>Information about user moods is provided by the user and propagated on the network by the user's client. The information is structured via a &lt;mood/&gt; element that is qualified by the 'http://jabber.org/protocol/mood' namespace. The mood itself is provided as the element name of a defined child element of the &lt;mood/&gt; element (e.g., &lt;happy/&gt;); one such child element is REQUIRED. The user MAY also specify a natural-language description of, or reason for, the mood in the &lt;text/&gt; child of the &lt;mood/&gt; element, which is OPTIONAL. Here is an example:</p>
    <code><![CDATA[
<mood xmlns='http://jabber.org/protocol/mood'>
  <happy/>
  <text>Yay, the mood spec has been approved!</text>
</mood>
]]></code>
    <p>In addition, an application MAY provide a more specific mood value as a properly-namespaced child of the defined element, which extension MUST be ignored if the receiving application does not understand the extended namespace. Here is an example:</p>
    <code><![CDATA[
<mood xmlns='http://jabber.org/protocol/mood'>
  <happy>
    <ecstatic xmlns='http://ik.nu/ralphm'/>
  </happy>
  <text>Yay, the mood spec has been approved!</text>
</mood>
]]></code>
  </section2>
  <section2 topic='Pubsub Transport' anchor='proto-pubsub'>
    <p>Mood information SHOULD be communicated and transported by means of the &xep0060; subset specified in &xep0163;. Because mood 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>
    <example caption='User Publishes Mood'><![CDATA[

        </mood>
      </item>
    </publish>
  </pubsub>
</iq>

    <p>The mood is then delivered to all subscribers:</p>

  <section2 topic='Including a Mood in a IM Message' anchor='proto-message'>
    <p>A user MAY provide a mood extension in a specific IM message in order to lend a defined emotional tone to text of that particular message. (This does not override the user's more general mood and is not intended to replace PEP as a more general transport method for user moods.)</p>

<section1 topic='Mood Values' anchor='moods'>
  <p>There exist various theories of human affect, mood, and emotion, including those promulgated by Frijda <note>Frijda, N. 1986. <cite>The Emotions</cite>. New York: Cambridge University Press.</note>, Ortony et al. <note>Ortony, A., Clore, G., and Collins, A. 1988. <cite>The Cognitive Structure of Emotions</cite>. Hillsdale, NJ:  Erlbaum.</note>, and Wierzbicka <note>Wierzbicka, A. 1992. Defining Emotion Concepts. <cite>Cognitive Science</cite> 16: 539-581.</note>. The taxonomy provided here mostly follows the Affective Knowledge Representation that has been defined by Lisetti <note>Lisetti, C. 2002. Personality, Affect, and Emotion Taxonomy for Socially Intelligent Agents. In <cite>Proceedings of FLAIRS 2002</cite>. Menlo Park, CA: AAAI Press.</note> in an effort to harmonize the prevailing theories in this area, as well as some work by Wierzbicka on cross-cultural studies of emotion. <note>Wierzbicka, A. 1999. <cite>Emotions across Languages and Cultures</cite>. Cambridge: Cambridge University Press.</note> Furthermore, the taxonomy provided here includes a number of common physical states in addition to moods, and also takes into account the specific context of instant messaging, including work done by other standards development organizations (e.g., the Wireless Village specifications contributed to the &OMA;) and instant messaging service providers (e.g., ICQ). Finally, lists of moods and physical states have been checked for commonality against studies of word frequency in the English language. <note>Leech, G., Rayson, P., and Wilson, A. 2001. <cite>Word Frequencies in Written and Spoken English</cite>. Harlow, England: Pearson Education.</note> to remove rarely used terms.</p>

<section1 topic='Mapping to Wireless Village Moods' anchor='wv-mapping'>
  <p>The Wireless Village (now "IMPS") specifications for mobile instant messaging define a number of presence attributes, encapsulated in the "StatusMood" information element <note>The Wireless Village Initiative: Presence Attributes v1.1 (WV-029); for further information, visit &lt;<link url='http://www.openmobilealliance.org/tech/affiliates/wv/wvindex.html'>http://www.openmobilealliance.org/tech/affiliates/wv/wvindex.html</link>&gt;.</note>. The following values are defined for StatusMood in Wireless Village, all of which map one-to-one from Wireless Village to the same values (albeit lowercase) in Jabber:</p>
  <ul>
    <li><p>ANGRY</p></li>
    <li><p>ANXIOUS</p></li>
    <li><p>ASHAMED</p></li>
    <li><p>BORED</p></li>
    <li><p>EXCITED</p></li>
    <li><p>HAPPY</p></li>
    <li><p>IN_LOVE</p></li>
    <li><p>INVINCIBLE</p></li>
    <li><p>JEALOUS</p></li>
    <li><p>SAD</p></li>
    <li><p>SLEEPY</p></li>
  </ul>
  <p>The full range of moods defined herein is richer than that defined in Wireless Village; no mapping is provided by this specification for mood values that are not present in Wireless Village, and any such mapping is the responsibility of a gateway between the two systems.</p>
</section1>
<section1 topic='Internationalization Considerations' anchor='i18n'>
  <p>The XML character data values of the &lt;value/&gt; elements is not intended to be presented to a human user and thus there is no special reason to include an 'xml:lang' attribute unless the sender includes a &lt;text/&gt; element as well (as explained in &rfc2277;, "internationalization is for humans"). It is the responsibility of the receiving application to provide localized text strings associated with the XML character data values defined herein, or some other appropriate presentation (e.g., graphical images that represent the mood).</p>
</section1>
<section1 topic='Security Considerations' anchor='security'>
  <p>Because user moods may be published to a large number of pubsub subscribers, users should take care in approving subscribers and in characterizing their current moods.</p>
