Because there is none such properties for Theater: http://dbpedia.org/snorql/?query=SELECT+DISTINCT+%24p+WHERE+{%0D%0A%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FTheatre%3E+%3Fp+%3Fo+.%0D%0A%0D%0A%0D%0A%0D%0A} So I guess this is normal that you get an empty resutlset for that sparql query :) Take care, Fred ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Dbpedia-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/dbpedia-discussion
