The IBM® WebSphere® Presence Server Component enhances applications with consolidated, real-time information regarding user availability, capability, and willingness to communicate.
Presence Server can collect and distribute presence information to enable awareness between users in the enterprise. Applications can use it to publish presence information.
Applications can also subscribe to presence information. When an application subscribes to presence information, Presence Server sends notifications, containing the presence information, to the application. Presence Server manages the presence information and maintains it in a database.
Presence Server is deployed as an enterprise application in a WebSphere Application Server environment.
