The IESG contact persons are Jon Peterson and Cullen Jennings. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-simple-presence-rules-10.txt Technical Summary There are three functions in a presence system; namely subscriptions, publishing and notifications. Authorization is a key function in presence systems. Authorization policies, also known as authorization rules, specify what presence information, when sending notifications, can be given to which watchers, and when. This specification defines an XML document format for expressing presence authorization rules. Such a document can be manipulated by clients using XCAP, although other techniques are permitted. Working Group Summary This document reflects WG consensus. It defines the Presence Authorisation rules. Censensus was particularly strong. This document heavily depends on draft-ietf-geopriv-common-policy defined by the geopriv WG. Protocol Quality This document was reviewed for the IESG by Jon Peterson. Hisham Khartabil was the PROTO shepherd for this document. Gen-ART review was provided by Pasi Eronen.
