Wikidata SPARQL query needs trimming

[Vainonen]

SPARQL query from Wikidata done by this PHP class can be simplified, when Wikipedia plugin has been made compatible with Skosmos 3 and fetching Wikipedia URLs is done with widget. By removing parts like this from code:

  ?link schema:about <$uri> ;
    a ?linktype ;
    schema:isPartOf ?whole ;
    schema:inLanguage ?lang .
