To: IETF-Announce Message-Id: Date: Wed, 19 Oct 2005 13:41:04 -0400 Cc: Internet Architecture Board , simple mailing list , RFC Editor Subject: [Simple] Protocol Action: 'A Session Initiation Protocol (SIP) Event Notification Extension for Resource Lists' to Proposed Standard The IESG has approved the following document: - 'A Session Initiation Protocol (SIP) Event Notification Extension for Resource Lists' as a Proposed Standard This document began as the product of the SIP for Instant Messaging and Presence Leveraging Extensions Working Group, and was completed by the Session Initiation Protocol Working Group. The IESG contact persons are Allison Mankin and Ted Hardie. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-simple-event-list-07.txt Technical Summary This document presents an extension to the Session Initiation Protocol (SIP)-Specific Event Notification mechanism (RFC 3265) for subscribing to a homogeneous list of resources. Instead of the subscriber sending a SUBSCRIBE for each resource individually, the subscriber can subscribe to an entire list, and then receive notifications when the state of any of the resources in the list changes. Working Group Summary The SIMPLE working group supported this capability strongly. The document was transferred to the SIP working group because it needed a SIP option tag. There was a delay while reviewing and revising its discussion of identity. The Open Mobile Alliance has expressed a critical requirement for this specification. Protocol Quality This protocol has been tested in SIMPLE interoperability sessions. It was reviewed for the IESG by Allison Mankin. Note to the RFC Editor OLD: Language tags are defined in RFC 1766 [6]. NEW: Language tags are defined in RFC 3066 [6]. Change reference [6] to a reference to RFC 3066.
