This document defines an extension mechanism for capturing "extended presence" data about user moods.

There exist various theories of human affect, mood, and emotion, including those promulgated by Frijda Frijda, N. 1986. The Emotions. New York: Cambridge University Press., Ortony et al. Ortony, A., Clore, G., and Collins, A. 1988. The Cognitive Structure of Emotions. Hillsdale, NJ: Erlbaum., and Wierzbicka Wierzbicka, A. 1992. Defining Emotion Concepts. Cognitive Science 16: 539-581.. The taxonomy provided here mostly follows the Affective Knowledge Representation that has been defined by Lisetti Lisetti, C. 2002. Personality, Affect, and Emotion Taxonomy for Socially Intelligent Agents. In Proceedings of FLAIRS 2002. Menlo Park, CA: AAAI Press. in an effort to harmonize the prevailing theories in this area, as well as some work by Wierzbicka on cross-cultural studies of emotion. Wierzbicka, A. 1999. Emotions across Languages and Cultures. Cambridge: Cambridge University Press. 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. Leech, G., Rayson, P., and Wilson, A. 2001. Word Frequencies in Written and Spoken English. Harlow, England: Pearson Education. to remove rarely used terms.

The Wireless Village (now "IMPS") specifications for mobile instant messaging define a number of presence attributes, encapsulated in the "StatusMood" information element The Wireless Village Initiative: Presence Attributes v1.1 (WV-029); for further information, visit <http://www.openmobilealliance.org/tech/affiliates/wv/wvindex.html>.. 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:

• ANGRY

• ANXIOUS

• ASHAMED

• BORED

• EXCITED

• HAPPY

• IN_LOVE

• INVINCIBLE

• JEALOUS

• SAD

• SLEEPY

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.

The XML character data values of the <value/> 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 <text/> 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).

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.
