Hi,

you can use the IRI of entities in SPARQL queries. IRI must be put inside <> in SPARQL, for example :

Query = ’’’PREFIX...SELECT ?owner WHERE {?owner :has_bought <’’’ +car.iri +”>.}”

where car is an Owlready individual.
Then you can execute the query:

results = default_world.as_rdflib_graph().query_owlready(Query)

results is a generator yielding the results of the query (here individuals). You can make a for loop over results, of transform it in a list as follows:

results = list(results)
print(results)

Best regards,
