ATOM
ATOM is the acronym for Atom Syndication Format.

Atom Syndication Format
A web syndication format, like RSS, which users utilize to publish and syndicate their content to subscribers. The Atom Syndication Format is a language used for web feeds, allowing users to keep track of updates to content provided by a website in a standardized format.
The specification for Atom was created to address shortcomings in the RSS standard and to offer a more robust and flexible format for content syndication. Atom feeds are XML files that follow the specific Atom standards and protocols outlined by the Internet Engineering Task Force (IETF). They are used to distribute regularly updated works—such as blog entries, news headlines, audio, and video—in a standardized format.
