A Atom Feed is part of a content syndication protocol developed from 2003 to 2007 and inspired by RSS.
- Atom Enabled is the home of the Atom protocol. Full explanations, examples, and a directory of sites and Apps published using the protocol can be found here.
- Two IETF standards describe it. The Atom Publishing Protocol (IETF RFC 5023) and the Atom Syndication Format (IETF RFC 4287).
- Wikipedia “Atom (standard)” provides an overview of the Atom history.
- Some of the project goals: “100% vendor-neutral”, “implemented by anyone”, “freely extensible by anyone”, and “cleanly and accurately specified”.
- Biggest differences to RSS: Atom is now managed by the IETF standard process, is written in XML and complies with the date and localization standards.
