Extensible Markup Language Formats for Representing Resource Lists

Overview

RFC 4826, “Extensible Markup Language Formats for Representing Resource Lists”, is a Proposed Standard document published in May 2007 by J. Rosenberg. The canonical text is published by the RFC Editor.

Abstract

In multimedia communications, presence, and instant messaging systems, there is a need to define Uniform Resource Identifiers (URIs) that represent services that are associated with a group of users. One example is a resource list service. If a user sends a Session Initiation Protocol (SIP) SUBSCRIBE message to the URI representing the resource list service, the server will obtain the state of the users in the associated group, and provide it to the sender. To facilitate definition of these services, this specification defines two Extensible Markup Language (XML) documents. One document contains service URIs, along with their service definition and a reference to the associated group of users. The second document contains the user lists that are referenced from the first. This list of users can be utilized by other applications and services. Both documents can be created and managed with the XML Configuration Access Protocol (XCAP). [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
