Expires August 19, 2004 [Page 1] Internet-Draft RPID February 2004 defines a textual note, an indication of availability (open or closed) and a Universal Resource Identifier (URI) for communication. The Rich Presence Information Data Format (RPID) described here is an extension that adds optional elements to the Presence Information Data Format (PIDF). These extensions provide additional information about the presentity and its contacts. The information is designed so that much of it can be derived automatically, e.g., from calendar files or user activity. This extension includes information about what the person is doing, a grouping identifier for a tuple, when a service or device was last used, the type of place a person is in, what media might be private, the relationship of a service tuple to another presentity, the person’s mood, the time zone it is located in, the type of service it offers and the overall role of the presentity. These extensions include characteristics and status information for person, service (tuple) and devices. Schulzrinne, et al. Expires August 19, 2004 [Page 2] Internet-Draft RPID February 2004
