API:Properties

Info: Parameters

 * : Which properties to get
 * : The protection level

By default, the following properties will be listed:
 * : page ID.

 * : whether the page has only one revision.

Info: Possible warnings

 * Action ' action ' is not allowed for the current user

None

revisions / rv
Returns revisions for a given page, or the latest revision for each of several pages. When using parameters marked as (enum),  must have only one title listed. The code for this query is located on the git repository at

Revisions: Parameters

Possible errors

 * code: clshow

 * What language to fetch extmetadata in. This affects both which translation to fetch, if multiple are available, as well as how things like numbers and various values are formatted.
 * If translations for extmetadata property are available, fetch all of them. The values of the multi-languaged metadata items will be in the multi-language array format. (Which items are multilanguaged might change from image to image.)
