For a version of this template with an opt-in toggle, see {{WikidataOI}}.
This template is used on approximately 176,000 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.
You might want to use one of the user-friendly wrapper templates {{Wikidata}} and {{WikidataOI}} instead of invoking this module directly.
