Module:Authority control: Difference between revisions

Latest revision as of 19:36, 13 November 2022

This Lua module is used on approximately 1,990,000 pages, or roughly 180745% of all pages.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.
Lua error in Module:Lua_banner at line 113: attempt to index field 'edit' (a nil value). This module contains the code of the {{Authority control}} template. See its documentation.
Parameters, Wikidata properties, and tracking categories

Lua error at line 1047: too many expensive function calls.
Additional tracking categories

This module also implements the following hidden tracking categories:
Category:Pages with red-linked authority control categories (0) – 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
Number of identifiers

-- If a link has a suitable entry in the global inter-wiki prefix table at [[:m:Interwiki_map]],
-- please consider routing through this prefix rather than as external link URL.
-- This will ease future maintenance as necessary updates to the link can be centrally carried out there rather than by updating this module.
