Template:Authority control/doc

Description
This metadata template links Wikipedia articles to various library (and other) catalogue systems, for biographies and other topics.

Position
As a metadata template, the Authority control template should be placed after the external links section and navigation templates, right before the categories.

Usage

 * Selective suppression via blank parameters:


 * Full (may not be up-to-date) :


 * The following data sources are accepted (may not be up-to-date):


 * The following data sources are deprecated

and will cause articles to be added to hidden tracking sub-categories of Category:Wikipedia articles with authority control information:

Additional tracking categories
This template may add the following categories:
 * – error category to identify missing categories
 * – fix/migrate/remove deprecated IDs
 * – tracking only (no error)
 * – migrate IDs to Wikidata if possible (no error)

Microformat
The template wraps each UID value with the HTML markup:, which enables the first-found value to be included in an hCard microformat. For that reason, VIAF, where present, is emitted first.
