IETF RFC 5263
Session Initiation Protocol (SIP) Extension for Partial Notification of Presence Information
| Organization: | IETF |

scope:
By default, presence delivered using the presence event package for the Session Initiation Protocol (SIP) is represented in the Presence Information Data Format (PIDF). A PIDF document contains a set of elements, each representing a different aspect of the presence being reported. When any subset of the elements change, even just a single element, a new document containing the full set of elements is delivered. This memo defines an extension allowing delivery of only the presence data that has actually changed.
