Using Graph not supported by Wikidata endpoint #21

Open vemonet opened 4 years ago

into-the-graph fail querying Wikidata endpoint due to the GRAPH ?graph { part, not supported in Blazegraph triple mode.

See https://query.wikidata.org/sparql

Add option to switch between Graph and Ntriple mode?

All graph instructions would be omitted from Ntriple SPARQL queries
