Atom guides
Look closely at feed structure.
Atom is a feed format with an explicit model for entry identity, dates, people, and content. This topic collection starts with the RSS comparison because a format decision is most useful when connected to the way a reader or parser will consume it.
Use the linked guide to compare the fields your publishing workflow already has with those your chosen format expects. Then open the Atom topic page for a shorter reference. Format choice does not remove the need for valid XML, stable identifiers, useful content, or deliberate handling of edits.
