Hi, I am facing a problem with querying data when the predicate is a a variable. This problem occurs when we need to use the inferences rules imported from OWL reasoner. Attached you can see my config file. And this is the query I am trying to run. When I use the user interface to execute this query, it keeps on spinning and won't return any result. When I stop the server after a while, I get this error: " Unable to get response from endpoint " I have run the same query in SnapSparql plugin in Protege and I got the right results from that. PREFIX base: <http://www.semanticweb.org/mahsaro/ontologies/2018/2/untitl ed-ontology-5#> PREFIX owl: <http://www.w3.org/2002/07/owl#> SELECT ?p ?o WHERE { ?p a owl:ObjectProperty . base:choice_three_tier_client_server_1 ?p ?o. } I would appreciate if you could help me with this problem. Kind regards, Mahsa Roodbari
