Thanks Federico. Much appreciated, but...besides creating extra layers inside of Wikidata just to expose external data correctly....
Still, there is a need to have 'external subclass' directly on the parent class of diet https://www.wikidata.org/wiki/Q474191
One reason is to ease the burden of SPARQL queries for both sides. Wikidata users/developers and Schema.org
We are tracking all of the work here: https://github.com/schemaorg/schemaorg/issues/280
SELECT * WHERE { {?property wdt:P2235 ?extsuper.} UNION { ?property wdt:P2236 ?extsub. } UNION { ?property wdt:P1628 ?extequiv. } UNION { ?property wdt:P1709 ?_equivalent_class. } FILTER( REGEX(STR(?extequiv), "schema.org") || REGEX(STR(?extsub), "schema.org") || REGEX(STR(?extsuper), "schema.org") || REGEX(STR(?_equivalent_class), "schema.org") ) }
