IETF Closes in on Linking Geographic Info, Presence

IETF Closes in on Linking Geographic Info, Presence: "Now, figures in the Internet communications community are working to take presence to the next level by creating a framework for merging users' location data into their presence information. That's long been viewed as a logical add-on to the basic availability data now available in most implementations of presence.

GEOPRIV is close to finalizing on a recommendation -- a Request for Comments, in IETF parlance -- for just such a system. That draft recommendation, authored by Neustar's Jon Peterson and known officially as 'A Presence-based GEOPRIV Location Object Format,' is actually based on earlier work done in formulating the basic requirements for presence data -- the Presence Information Data Format (PIDF).
