It is where a page can have multiple content handlers associated with it. The most common example is commons file pages. They have normal wikitext page, but they also have a slot containing wikidata-style data structured data.
Whether or not you have to worry about this depends on what you're doing. For most things probably no, but more things might have multiple slots in the future. -- Bawolff On Sunday, April 5, 2020, Petr Bena <benap...@gmail.com> wrote: > Hello, > > https://www.mediawiki.org/wiki/API:Revisions mentions "revision slots" > multiple times, but fails to explain what it is? > > I noticed that some queries that were running fine in the past now > have warning: "Because "rvslots" was not specified, a legacy format > has been used for the output.
