Atom 1.0

Atom 1.0, defined by IETF RFC 4287, is an XML-based syndication format developed as a more rigorously specified alternative to RSS 2.0. An Atom feed (atom:feed) contains required atom:id, atom:title, atom:updated, and atom:author elements plus a sequence of atom:entry items each with their own id, title, updated, and content or summary. Atom uses the namespace http://www.w3.org/2005/Atom and the application/atom+xml media type.
