From: The IESG To: IETF-Announce Message-Id: Date: Thu, 31 Mar 2005 10:14:53 -0500 Subject: Protocol Action: 'Functional Description of Event Notification Filtering' to Proposed Standard The IESG has approved the following documents: - 'Functional Description of Event Notification Filtering ' as a Proposed Standard - 'An Extensible Markup Language (XML) Based Format for Event Notification Filtering ' as a Proposed Standard These documents are products of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group. The IESG contact persons are Ted Hardie and Scott Hollenbeck. Technical Summary The SIP event notification framework describes the usage of the Session Initiation Protocol (SIP) for subscriptions and notifications of changes to a state of a resource. The initial specification did not describe a mechanism for filtering event notifications. Filtering is a mechanism for defining the preferred notification information to be delivered and for specifying triggers that cause that information to be delivered. In order to enable this, a format is needed to enable the subscriber to choose when notifications are to be sent to it and what they are to contain. This document presents a solution in the form of an XML document format. Working Group Summary The SIMPLE working group came to consensus on this document. There were Last Call comments from the IETF community, and there were change incorporated into the document to reflect the responses to those comment.s Protocol Quality This document was reviewed for the IESG by Ted Hardie.
