An Atom feed is a web feed that uses the Atom Syndication Format and the Atom Publishing Protocol. Atom comprises an XML-based format that describes an Atom feed and the items of information in it, and a protocol for publishing and editing Atom feeds. This format and protocol are described in two Internet Society and IETF (Internet Engineering Task Force) Request for Comments documents (known as RFCs):
- RFC 4287, The Atom Syndication Format, available from http://www.ietf.org/rfc/rfc4287.txt
- RFC 5023, The Atom Publishing Protocol, available from http://www.ietf.org/rfc/rfc5023.txt
