Main differences between Atom 1.0 and RSS 2.0:

  • Atom has separate "summary" and "content" elements, while RSS only has one "description" element.
  • Atom standardizes auto-discovery in contrast to the many non-standard variants used with RSS 2.0.
  • In Atom, it is mandatory that each entry have a globally unique ID, which is important for reliable updating of entries.
  • Atom 1.0 allows standalone Atom Entry documents whereas with RSS 2.0 only full feed documents are supported.
  • Atom specifies that dates be in the format described in RFC 3339. The date format in RSS 2.0 was underspecified and has led to many different formats being used.
