The Query source property is a special property in Semantic MediaWiki with a built-in meaning: it holds the identifier of an alternative (e.g. remote) query source used in a query. It is not possible to manually add a value to this special property. It is however indirectly taken from the value added to the source parameter to parser function #ask which is provided by extension "Semantic External Query Lookup"Allows to seamlessly integrate query results from an external query source to a local repository or wiki. It was introduced with Semantic MediaWiki 2.5.0Released on 14 March 2017 and compatible with MW 1.23.0 - 1.29.x..1
