This documentation is transcluded from Template:BCP47/doc.

This template fixes the current violations of the BCP47 standard (for inclusion in the lang HTML attribute) by Wikimedia sites for their language codes.

It also normalizes these codes to lowercase only (though it is not mandatory).

Use this template in the HTML lang="" attribute , or CSS language selectors (where BCP47 conformance is mandatory per their relevant standards), or in Wikidata for identifying the language of translated item labels and aliases (with language codes that all should all conform to BCP47). Don't use it not for interwiki codes (that are not necessarily BCP47 language codes, but used as domain names labels (also in internal Wikimedia database names) for Wikimedia projects designed to group one or several languages or variants in the same edition of the project and that may locally violate BCP 47 rules for verious legacy codes (even if some of them have been deprecated). Various non-Wikimedia projects may use other codes for their projects, but they are not directly supported unless they conform to BCP 47 (you may need other template to map language codes for these external projects). Do not assume that any interwiki code which is valid inside Wikimedia for wikilinks inserted in wiki pages is a valid BCP47 code.

As of August 2024, a new #bcp47 parser function was added which fully replaces this template. Please use {{#bcp47:...}} instead of {{BCP47|...}} template.

TemplateData

TemplateData is a way to store information about template parameters (the description of those and of the whole template) for both humans and machines. It is used by VisualEditor and possibly other tools like Upload Wizard.

Existing template documentation
At Wikimedia Commons, it is recommended to use {{TemplateBox}} with either ‎useTemplateData=1 or ‎useTemplateData=only on the ‎/doc subpage and transcluding it with {{Documentation}} into the template. ‎<nowiki>-tags can be wrapped around the arguments, if required, to avoid templates being expanded.

Newly created template documentation and imports
Another option, especially for imported templates, or for users with JSON experience, is placing raw ‎<templatedata>-tags into the Wikitext of the template, as described in various Wikipediae.
