Dear all, I did the following query to the dbpedia through www.dbpedia.org/sparql
PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> PREFIX p: <http://dbpedia.org/property/> SELECT ?player ?club WHERE{ ?player p:cityofbirth <http://dbpedia.org/resource/Stryn>. OPTIONAL {?player p:currentclub ?club}} In it I get the following results: player club http://dbpedia.org/resource/Jarle_Flo http://dbpedia.org/resource/H%C3%A5vard_Flo http://dbpedia.org/resource/Retired http://dbpedia.org/resource/Tore_Andr%C3%A9_Flo http://dbpedia.org/resource/Milton_Keynes_Dons_F.C. http://dbpedia.org/resource/Jostein_Flo Strømsgodset (director of football) http://dbpedia.org/resource/Per_Egil_Flo http://dbpedia.org/resource/Sogndal_Fotball Next I do the following query (in which I query for all the players who belong to a club): SELECT ?player ?club WHERE { ?player <http://dbpedia.org/property/currentclub> ?club .} And I get results but I do not get the following results: http://dbpedia.org/resource/Tore_Andr%C3%A9_Flo http://dbpedia.org/resource/Milton_Keynes_Dons_F.C. http://dbpedia.org/resource/Per_Egil_Flo http://dbpedia.org/resource/Sogndal_Fotball http://dbpedia.org/resource/H%C3%A5vard_Flo http://dbpedia.org/resource/Retired The purpose of these queries is to do locally the join operator but I get different results from the basic queries so I do not get the proper results. Any idea? I do not know what I'm missing :S Thanks, Carlos ------------------------------------------------------------------------------ Come build with us!
