This document defines an extension mechanism for capturing "extended presence" data about user moods.
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 <mood/> 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 <mood/> element (e.g., <happy/>); one such child element is REQUIRED. The user MAY also specify a natural-language description of, or reason for, the mood in the <text/> child of the <mood/> element, which is OPTIONAL. Here is an example:
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:
Mood information SHOULD be communicated and transported by means of the Publish-Subscribe (XEP-0060)  subset specified in Personal Eventing Protocol (XEP-0163) . 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/>.
The mood is then delivered to all subscribers:
In order to indicate that the user is no longer publishing moods, the user's client shall send an empty <mood/> element, which can be considered a "stop command" for user moods:
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.)
There exist various theories of human affect, mood, and emotion, including those promulgated by Frijda , Ortony et al. , and Wierzbicka . The taxonomy provided here mostly follows the Affective Knowledge Representation that has been defined by Lisetti  in an effort to harmonize the prevailing theories in this area, as well as some work by Wierzbicka on cross-cultural studies of emotion.  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 Open Mobile Alliance (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.  to remove rarely used terms.
The following mood values are defined in this taxonomy. Where available as linked below, the definitions are obtained from Wiktionary.

The Wireless Village (now "IMPS") specifications for mobile instant messaging define a number of presence attributes, encapsulated in the "StatusMood" information element . 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:
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 RFC 2277 , "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.
This document requires no interaction with the Internet Assigned Numbers Authority (IANA) .
