• Publishing a web feed: RSS 2.0, Atom or JSON Feed, and the details readers depend on

  Atom requires an id, title and updated per feed and entry with RFC 3339 dates; RSS 2.0 requires channel title, link and description, uses RFC 822 dates and a guid whose isPermaLink defaults to true; JSON Feed 1.1 requires version, title and items with an id and content, served as application/feed+json. Stable IDs, full content, conditional GET and autodiscovery matter more than the format choice.
