Module documentation[view] [edit] [history] [purge]

This Lua module is used on many pages.

To avoid large-scale disruption and unnecessary server load, any changes to this module should first be tested in its /sandbox or /testcases subpages. The tested changes can then be added to this page in one single edit.

Please consider discussing any changes on the talk page before implementing them.

<translate> This module is [[<tvar name=1>Special:MyLanguage/Category:Modules subject to page protection</tvar>|subject to {{<tvar name=2>#if:</tvar>|cascading|page}} protection]].</translate> <translate> It is a highly visible module in use by a very large number of pages.</translate> <translate> Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is [[<tvar name=1>Special:MyLanguage/Project:Protected page</tvar>|protected]] from editing.</translate>

This module depends on the following other modules:

This module contains the code of the {{Authority control}} template. See its documentation.

Parameters, Wikidata properties, and tracking categories

Lua error in package.lua at line 80: module 'strict' not found.

Additional tracking categories

This module also implements the following hidden tracking categories:

Category:Pages with red-linked authority control categories (1) – error category to identify missing categories
Category:Articles with deprecated authority control identifiers (0) – fix/migrate/remove deprecated IDs
Category:Articles with suppressed authority control identifiers (0) – tracking only (no error)
Category:Articles with multiple identifiers (0) – tracking only (no error)
Category:Pages using authority control with parameters (0) – migrate IDs to Wikidata, if possible (no error)
Category:Pages using authority control with parameters different on Wikidata (0) – determine/remove incorrect IDs & migrate to Wikidata
Category:Pages using authority control with parameters all matching Wikidata (0) – template parameters may safely be removed
