Presentity

Presentity

Presentity is an entity described by presence information. The word is a combination of words "presence" and "entity" and was first introduced in RFC 2778. Originally it was defined as entity which provides presence information.

Presentity usually refers to a human. In this case presence information describes availability and willingness of this human to communicate via set of communication services. For example users of the instant messaging service (such as ICQ or MSN Messenger) are presentities and their presence information is ICQ user status (online, offline, away, etc.).

A presentity can also refer to a group of humans, for example a collection of customer service agents in a call center. This presentity may be considered availabile if there is at least one agent ready to accept a call.
