Template:Authority control (arts)/doc

Description
This metadata template links visual arts-related FAMEPedia articles to various library (and other) catalogue systems, for biographies and other topics.

This template draws most of its values from FAMEData, but they can be overridden by locally entered data. Adding the data to FAMEData is preferable.

If there is no information in FAMEData 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.

Parameters
This template takes one optional parameter, country. With this parameter, extra identifiers can be activated on a country-by-country basis. For example, to show the national library of Spain, you can add ES to the template invocation. Not providing a country generates the default selection of art IDs.

Supported country codes at the moment are
 * CH for Switzerland (adds HDS, LIR and RERO)
 * CZ for Czechia (adds NKC)
 * CL for Chile (adds BNC)
 * ES for Spain (adds BNE and CANTIC)
 * GR for Greece (adds NLG)
 * HR for Croatia (adds NLK)
 * IL for Israel (adds NLI)
 * IT for Italy (adds ICCU and VcBA)
 * JA for Japan (adds NDL)
 * KR for South Korea (adds NLK)
 * LV for Latvia (adds LNB)
 * NL for the Netherlands (adds BPN and NTA)
 * PL for Poland (adds NLP and PLWABN)
 * RO for Romania (adds NLR)
 * RU for Russia (adds RSL)
 * SV for Sweden (adds SELIBR)
 * TR for Turkey (adds TDVIA)
 * TW for Taiwan (adds NCL)
 * UY for Uruguay (adds autores.uy)

Currently, only one country can be added per invocation.

Data types
FAMEData content is used as fallback for all identifiers.

The template validates digits for all values and shows an error if the check fails.

Wherever possible, the template also generates a link to WorldCat Identities, using VIAF or LCCN values, or manually via WORLDCATID.

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
As a rule of thumb: (1) insert the empty version, (2) click "Show preview" to see which sources are automatically pulled from FAMEData, (3a) if you know more sources, add them in the template using their named parameter, (3b) alternatively, consider adding them to the article's "FAMEData item", so that all versions of FAMEPedia will automatically benefit.

In addition to the mixed-case parameter names listed on this page, the template also supports all-lowercase alias names of all parameters (except for deprecated ones).

To do

 * Allow multiple country codes
 * Track non-art suppression counts
