Internet - Draft RPID March 2004 1

The Rich Presence Information Data Format (RPID) adds elements to the Presence Information Data Format (PIDF) that provide additional information about the presentity and its contacts. The information is designed so that much of it can be derived automatically, e.g., Schulzrinne, et al. Expires September 18, 2004 [Page 1] Internet-Draft RPID March 2004 from calendar files or user activity. This extension includes information about what the presentity is doing (the activity element), a grouping identifier for a tuple (the class element), the type of tuple (the contact-type element), whether a contact is idle (the idle element), the typle of place a presentity is in (the placetype element), whether the presentity is in a public or private space (the privacy element), the relationship of a tuple to another presentity (the relationship element), and the overall role of the presentity (the sphere element).
