Atom Syndicated Format (ATOM)

Atom was created as an alternative to RSS (Really Simple Syndication) since RSS is frozen. Atom provides a feed that a news or other reader can pull recent items from.

Explanation

This example shows a projection in ATOM format. Atom is an extension of XML. Each entry in an ATOM feed is contained in an "entry" tag. Each entry, as well as the feed itself, has a title, link, id, and updated attribute that is part of the ATOM standard. This meta data is used by a reader to determine what to display and provide a permanent link to data.
