 | This is the template sandbox page for Template:Authority control (diff). See also the companion subpage for test cases. |
 | This template is used on approximately 2,160,000 pages, or roughly 3% of all pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

Description
[edit]This template links Wikipedia articles to various library (and other) catalogue systems, for biographies and other topics.
This template draws its values from Wikidata. A pencil icon 
gives convenient access to the "Identifiers" section of the corresponding Wikidata item.
Empty instances
[edit]If there is no information in Wikidata for the specific subject, an empty instance of this template will be dormant, meaning it will be invisible on the rendered page. Thus, using this template on a page with no authority information is harmless. An empty instance of this template stays dormant in an article, until values are added to Wikidata, when it will then display them.
Validation
[edit]The template attempts to validate digits for all values and shows an error if the check fails.
Position
[edit]As a metadata template, the Authority control template should be placed on a new line, after the external links section and navigation templates, immediately before the categories.
Usage
[edit]As a general guideline:
- Insert the empty version
- Click "Show preview" to see which sources are automatically pulled from Wikidata
- If you know of more sources, add those sources to the article's Wikidata item, so that other language versions of Wikipedia will automatically benefit.
Suppression of identifiers
[edit]Identifiers can be selectively suppressed via the |suppress= parameter. For example MusicBrainz artist ID (P434) can be suppressed by typing:
Specifying the Wikidata item
[edit]If a page is not connected to a Wikidata item (for example, a page in draft space, user space or project space), you can specify the appropriate item to draw data from, by using the |qid= parameter.
To find the correct item, you can search the database. If there is not yet an existing item, you can create a new item.
As soon as the page is connected to a Wikidata item, this parameter will be ignored so you can remove it from the template.
Additional Wikidata items
[edit]In some cases, you might need to specify additional items to draw data from. For example,
- Bonnie and Clyde also draws data from Bonnie Parker (Q2319886) and Clyde Barrow (Q3320282)
- North Rona also draws data from North Rona Lighthouse (Q28831543)
To specify additional items, you can use the |additional= parameter. For example:
To automatically add additional links from related items, use |additional=auto. This is useful for married couples, musical groups, etc.
Whitelists
[edit]A number of whitelists are configured, which allow only a limited selection of identifiers to be displayed. These can be used with the |show= parameter. For example, including |show=arts will only show identifiers which have identified as particularly relevant to the arts.
Multiple whitelists may be used. For example:
adds identifiers from the arts and Sweden whitelists.|country= can be used as an alias for |show=.

Rendering
[edit]The template is split into a number of sections, including "International", "National", "Academics", "Artists" etc. The template usually displays as a navbox with a header:
| International | |
|---|---|
| National | |
| Academics | |
| Artists | |
| People | |
| Other | |
If all identifiers are in the same section, |state= is ignored, and the template displays on one line.
If you use additional qids to draw data from additional wikidata items, then a new section will be added for each. In this case, the identifiers will not be separated further:
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{Authority control|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Authority control|state=expanded}}will show the template expanded, i.e. fully visible.
Microformat
[edit]The template wraps each UID value with the HTML markup: <span class="uid">...</span>, which enables the first-found value to be included in an hCard microformat.
List of identifiers
[edit]Expression error: Unrecognized punctuation character ",".
The template gets its information from the following properties on Wikidata: Lua error in Module:Authority_control/documentation/sandbox at line 37: attempt to index field 'datavalue' (a nil value).
Additional tracking categories
[edit]This template may add the following categories:
- Category:Pages with authority control identifiers needing attention (1) – category to track errors
- Category:Pages using authority control with unknown parameters (0) – identifiers should be migrated to Wikidata
- Category:Articles with faulty authority control information (1,271) – faulty identifiers to fix
Error reports
