An Extensible Markup Language Based Format for Watcher Information
RFC 3858, “An Extensible Markup Language Based Format for Watcher Information”, is a Proposed Standard document published in August 2004 by J. Rosenberg. The canonical text is published by the RFC Editor.
Abstract
Watchers are defined as entities that request (i.e., subscribe to) information about a resource. There is fairly complex state associated with these subscriptions. The union of the state for all subscriptions to a particular resource is called the watcher information for that resource. This state is dynamic, changing as subscribers come and go. As a result, it is possible, and indeed useful, to subscribe to the watcher information for a particular resource. In order to enable this, a format is needed to describe the state of watchers on a resource. This specification describes an Extensible Markup Language (XML) document format for such state. [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.
