The IESG has approved the Internet-Drafts 'A Presence Event Package for the Session Initiation Protocol (SIP)' <draft-ietf-simple-presence-10.txt>, 'A Session Initiation Protocol (SIP) Event Template-Package for Watcher Information' <draft-ietf-simple-winfo-package-05.txt> and 'An Extensible Markup Language (XML) Based Format for Watcher Information' <draft-ietf-simple-winfo-format-04.txt> as Proposed Standards. These documents are products of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group. The IESG contact persons are Ned Freed and Patrik Faltstrom. Technical Summary The main document describes the usage of the Session Initiation Protocol (SIP) for subscriptions and notifications of presence. Subscriptions and notifications of presence are supported by defining an event package within the general SIP event notification framework. The supporting documents define the watcher information template-package, and an XML document format for the state of watchers on a resource. Working Group Summary There was consensus for these documents in the working group. Protocol Quality The documents were reviewed for the IESG by Patrik Faltstrom and Allison Mankin. RFC Editor Note: Replace the first paragraph in section 5, which currently reads: A presentity is identified in the most general way through a presence URI [3], which is of the form pres:user@domain. These URIs are protocol independent. They are resolved to protocol specific URIs, such as a SIP or SIPS URI, through domain-specific mapping policies. with: A presentity is identified in the most general way through a presence URI [3], which is of the form pres:user@domain. These URIs are such as a SIP or SIPS URI, through domain-specific mapping policies maintained on the server. (i.e., add the text "maintained on the server" to the end of the last sentence).
