7.5.3 Atom

Some web sites provide an Atom Syndication Format feed. Atom is a web feed format similar in function to RDF Site Summary (see RSS).

The nnatom back end allows you to add HTTP or local Atom feeds as Gnus servers, by adding them to gnus-secondary-select-methods or as foreign servers by pressing "B" in the *Group* buffer, for example (see Finding the News). The address of each server is its feed’s location (though the address shouldn’t be prefixed with <http://> or <https://>) and each server contains a single group which holds the feed’s entries.

Features of nnatom include:

• Server data is saved per-server in the atom sub-directory of gnus-directory.
• An article part is generated for both the summary and the content for each entry in the feed. Content of all MIME types should be displayed correctly through Gnus (as long as they are supported and the feed specifies a MIME type).
• Article modification and publish dates are tracked, and articles are updated if changed.
