Hi Janna,
What datasets are loaded in your local Virtuoso instance as I see you
reference the <http://dbpedia.org> graph in it , so do you already have some
DBpedia datasets loaded ?
Note the query you are running locally is not the same as what you are running
against the canonical dbpedia endpoint ie http://dbpedia.org/sparql, which
should be:
SELECT distinct ?p ?label
WHERE
{
SERVICE <http://dbpedia.org/sparql> {<http://dbpedia.org/resource/Tallinn>
?p ?o . ?p rdfs:label ?label . FILTER (lang(?label) = 'en') }
}
limit 10
ie all triple patterns should be in the "SERVICE" part for remote execution,
unless you have local DBpedia data load in which case I would suggest it does
not contain the expected data possibly ?
See following live example from our LOD Server that works:
http://lod.openlinksw.com/sparql/?default-graph-uri=&qtxt=SELECT+distinct+%3Fp+%3Flabel+%0D%0AWHERE%0D%0A%7B%0D%0A++++%0D%0A++++SERVICE+%3Chttp%3A%2F%2Fdbpedia.org%2Fsparql%3E+%7B%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FTallinn%3E+%3Fp+%3Fo+.+%3Fp+rdfs%3Alabel+%3Flabel+.+FILTER+%28lang%28%3Flabel%29+%3D+%27en%27%29+%7D%0D%0A%7D%0D%0Alimit+10&format=text%2Fhtml&CXML_redir_for_subjs=121&CXML_redir_for_hrefs=&timeout=30000&debug=on
