Modul:EditAtWikidata

-- Module to display an icon with a tooltip such as "Edit this at Wikidata"
-- Icon will be linked to the Wikidata entry for the article where this is placed.
-- This message is only displayed if a local_parameter is not supplied
-- i.e. when called from a template, it can be coded not to display the message 
-- when a local parameter is in use, preventing the value form Wikidata being fetched.
-- The qid of a Wikidata entry can optionally be supplied for testing outside the article.
-- Usage:
-- {{#invoke:EditAtWikidata|showMessage|local_parameter}}
-- {{#invoke:EditAtWikidata|showMessage|qid=<ArticleID>|local_parameter}}
