The Atom Publishing Protocol (rfc 5023)

The Atom Publishing Protocol (AtomPub) is an application-level protocol for publishing and editing Web resources. The protocol is based on HTTP transfer of Atom-formatted representations. The Atom format is documented in the Atom Syndication Format.

The protocol supports the creation of Web Resources and provides facilities for:

• Collections: Sets of Resources, which can be retrieved in whole or in part.
• Services: Discovery and description of Collections.
• Editing: Creating, editing, and deleting Resources.

The Atom Publishing Protocol is different from many contemporary protocols in that the server is given wide latitude in processing requests from clients.
