This module is copied from the example from the module documentation at mw:Extension:Wikibase Client/Lua. It should be kept consistent with that documentation, rather than being adapted further for use on Wikipedia.

Usage

id
{{#invoke: Wikibase | id }}
wdurl
{{#invoke: Wikibase | wdurl }}
{{#invoke: Wikibase | wdurl | entity id (Q# or P#) }}
label
{{#invoke: Wikibase | label }}
{{#invoke: Wikibase | label | entity id (Q# or P#) }}
description
{{#invoke: Wikibase | description }}
{{#invoke: Wikibase | description | entity id (Q# or P#) }}
page
{{#invoke: Wikibase | page }}
{{#invoke: Wikibase | page | item id (Q#) }}
datatype
{{#invoke: Wikibase | datatype | property id (P#) }}
