Wikidata Query/Scholarly

Wikidata Query scholarly is a spin-off of the main Wikidata Query.

For performance reasons a separate instance is created, only containing scholarly publications.

You will no longer get scholarly articles via the standard Wikidata Query instance.

Example

SELECT ?item ?itemLabel WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en". }
  ?item wdt:P50 wd:Q136356082.
}

See https://w.wiki/FReV

Complications

SPARQL queries that require both scholarly, and standard data, requires the use of both query instances, so must be rewritten.
