Hi, I'm a jena newbie. I am trying to load the DBpedia's Ontology Infoxbox properties http://downloads.dbpedia.org/3.8/en/mappingbased_properties_en.ttl.bz2, http://wiki.dbpedia.org/Downloads38#h227-1 into a Fuseki server running on my machine.
For that I did the following 1. Create the tdb using the following command java tdb.tdbloader --loc=dbpedia mappingbased_properties_en.ttl 2. Ran the server using the following .\fuseki-server.bat --loc=../dbpedia /dbpedia Trying a simple query like PREFIX dbpedia: <http://dbpedia.org/resource/> PREFIX dbpedia-owl: <http://dbpedia.org/ontology/> PREFIX foaf: <http://xmlns.com/foaf/0.1/> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> select ?s ?p ?o where {?s ?p ?o.} LIMIT 100 works just fine giving results like | dbpedia:Animal_Farm | foaf:name | "Animal Farm"@en | dbpedia:Animal_Farm | foaf:name | "Animal Farm: A Fairy Story"@en | dbpedia:Animal_Farm | dbpedia-owl:author | dbpedia:George_Orwell The problem happens when I do something like select ?s ?o where {?s foaf:name ?o.} LIMIT 100 where I get empty results. select ?p ?o where {dbpedia:Animal ?p ?o.} LIMIT 100 However, when specifying the subject instead, I get the correct results. Any ideas why specifying the predicate or the object doesn't work? Note: The exact query works just fine on DBpedia. I'm therefore suspecting Fuseki but I'm unable to pinpoint the reason why it's not working -- Best Regards, Ahmed Sobhi http://about.me/humanzz
