I was just playing around w/ some SPARQL using dbpedia's endpoint and
noticed that:
SELECT *
WHERE {
?person rdf:type <http://dbpedia.org/ontology/Person> .
?person rdfs:label ?personName .
?person <http://dbpedia.org/ontology/birthplace> ?place .
?place rdfs:label ?placeName .
FILTER (lang(?personName) = "en")
FILTER (lang(?placeName) = "en")
}
returns some hits but this returns 0:
SELECT COUNT(*)
WHERE {
?person rdf:type <http://dbpedia.org/ontology/Person> .
?person rdfs:label ?personName .
?person <http://dbpedia.org/ontology/birthplace> ?place .
?place rdfs:label ?placeName .
FILTER (lang(?personName) = "en")
FILTER (lang(?placeName) = "en")
}
Is there something wrong here either in my query or my expectation
that the count query return > 0 ?
