Thad, Shouldn't the following query return all Classes participating in an <https://www.wikidata.org/wiki/Property:P1709> relation? : SELECT ?s ?relation ?o WHERE { ?s <https://www.wikidata.org/wiki/Property:P1709> ?o. BIND (<https://www.wikidata.org/wiki/Property:P1709> AS ?relation) } LIMIT 100 Query Link: https://query.wikidata.org/#%0A%0ASELECT%20%3Fs%20%3Frelation%20%3Fo%0AWHERE%20%7B%20%3Fs%20%3Chttps%3A%2F%2Fwww.wikidata.org%2Fwiki%2FProperty%3AP1709%3E%20%3Fo.%20%0A%20%20%20%20%20%20%20%20BIND%20%28%3Chttps%3A%2F%2Fwww.wikidata.org%2Fwiki%2FProperty%3AP1709%3E%20AS%20%3Frelation%29%20%0A%20%20%20%20%20%20%7D%20%0ALIMIT%20100%0A If not, can you formulate something closer to that output which makes matters easier should you not have an RDF dump available etc..
