Hello Michael, Actually, both should not work. The URL should be encoded, so either http://dbpedia.org/resource/Time_%28magazine%29 or :Time_%28magazine%29
I was actually surprised to also find http://dbpedia.org/resource/Time_(magazine) in DBpedia, so they are different URIs, which is obviously wrong. I think the yago dataset has bad url encoding and should be fixed. Regards, Sebastian, AKSW Michael Haas schrieb: > Hello, > > I'm trying to run some SPARQL queries.
