Presence plays an important role in facilitating efficient real-time communications. Presence refers to information used to describe an entity’s availability, willingness, or capability to communicate with other entities. The presence information can help a communicating party determine if, when, and how to contact other parties.
In a Microsoft Lync Server 2010 deployment, a communication entity can be a user or a trusted application such as a Web service, an interactive bot, or the Lync Server Response Group application. The user corresponds to a security principle represented by an Active Directory Domain Services User object and the trusted application is represented by an Active Directory Contact object. A communication entity that makes its presence available is referred to as a presence entity.
This chapter describes the enhanced presence data model and enhanced presence service operations, including publication and subscription.

The versatility is supported by a flexible XML-based presence data model as represented by the enhanced presence category.
