(SPARQL) Querying a SPARQL endpoint

(SPARQL) Running SPARQL queries

The query command can be used to run SPARQL queries on RDF data.

rudof query -q examples/user.sparql examples/user.ttl
?person    ?name   ?status        
     :b    "Bob"  :Waiting
     :a  "Alice"   :Active

It is also possible to run a SPARQL query that obtains its data from a SPARQL endpoint. For example, the following command:

$ rudof query -q examples/wikidata.sparql -e wikidata
?person        ?birth_place               ?label   ?birth_place_name
