Technical Summary This document utilizes the extention mechanisms within the Presence Information Document Format (PIDF) adding optional elements with additional information about the presentity and its contacts. This extension focuses on allowing a presentity to describe aspects of its historic status for an interval of time in the past, or its expected status for an interval of time in the future (timed-status). Working Group Summary This document reflects WG consensus. It is related to, and was split out from, the Rich Presence Information Document format (RPID) work to facilitate building consensus. The semantics of advertising presence for a time that is not now were thouroghly debated and clarified in this document. Protocol Quality Robert Sparks was the PROTO shepherd for this document.
