Abstract
A method and system for increasing the computational and network efficiency of presence servers having collections of publications is provided. The presence system uses several techniques that enable a presence server to provide rich presence information without requiring expensive processing. First, the presence system accepts batches of publication updates in a single presence update request. Similarly, the presence system accepts batches of subscription requests. Next, the presence system supports new expiration types for publication update requests that eliminate the need for a publishing user to continually refresh presence information that has not changed. Finally, the presence system accepts access lists that contain membership groups rather than an individual list of users that are to have access to a particular presence collection.
