Hi all. I wonder how I can get an intersection in SPARQL. Here is the use case: In DBPedia, there is a predicate called <http://dbpedia.org/property/actor>. In this triple pattern: ?s <http://dbpedia.org/property/actor> ?actor . ?actor a ?typeOfActor ?typeOfActor can be: http://www.w3.org/2002/07/owl#Thing http://schema.org/Person http://xmlns.com/foaf/0.1/Person http://www.ontologydesignpatterns.org/ont/dul/DUL.owl#Agent http://www.ontologydesignpatterns.org/ont/dul/DUL.owl#NaturalPerson http://wikidata.dbpedia.org/resource/Q215627 http://wikidata.dbpedia.org/resource/Q5 http://dbpedia.org/ontology/Agent http://dbpedia.org/ontology/Person http://dbpedia.org/class/yago/Actor109765278 http://dbpedia.org/class/yago/ActorsFromLiverpool http://dbpedia.org/class/yago/Adult109605289 http://dbpedia.org/class/yago/CausalAgent100007347 http://dbpedia.org/class/yago/Educator110045713 http://dbpedia.org/class/yago/Entertainer109616922 http://dbpedia.org/class/yago/LivingThing100004258 http://dbpedia.org/class/yago/Object100002684 http://dbpedia.org/class/yago/Organism100004475 http://dbpedia.org/class/yago/Performer110415638 http://dbpedia.org/class/yago/Person100007846 http://dbpedia.org/class/yago/Professional110480253 http://dbpedia.org/class/yago/Teacher110694258 http://dbpedia.org/class/yago/Whole100003553 http://dbpedia.org/class/yago/YagoLegalActorGeo My need is to retrieve only the ?typeOfActor that are common to all the ?actor(s). I still have no clue how to do that in SPARQL. Any help would be very welcome. (and any strategy to do that in SPARQL 1.0 would be interesting too)
