Abstract
The Presence Information Data Format (PIDF) defines a basic format
for representing presence information for a presentity. This format
defines a textual note, an indication of availability (open or
closed) and a Uniform 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 communications
might remain 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, an icon reflecting the presentity's
status, and the overall role of the presentity.
These extensions include presence information for persons, services
(tuples), and devices.
