The Internet Engineering Task Force (IETF) standards body has approved the Atom 1.0 data syndication format as...
a “proposed standard”.
Atom is a potential rival to the increasingly popular RSS standard.
Both are designed for publishing XML-based syndication feeds on websites and blogs, to send headlines and summaries of new postings to Web users.
Weblogs and news websites commonly use these feeds to send instantaneous headlines and summaries of new postings and stories.
Google already supports both Atom and RSS. An increasing number of media outlets are using RSS to raise their advertising revenues by including ads in the RSS feeds they send out from their sites.
