You’re using the wrong URI to identify DBPedia resources. On DBPedia, http://dbpedia.org/resource/Automobile
refers to the noun ‘automobile’, while http://dbpedia.org/page/Automobile
refers to a page describing the noun ‘automobile’. Thus,
SELECT DISTINCT * WHERE {
?carManufacturer dbpedia-owl:product <http://dbpedia.org/resource/Automobile>.
?carManufacturer dbpprop:locationCountry "France"@en.
} LIMIT 100
works just fine.
However, if you want to be a bit more idiomatic, you can use a bit of syntactic sugar to eliminate the subject repetition in your query. DBPedia also loads http://dbpedia.org/resource/
as prefix dbpedia
, so you can actually eliminate all URIs from your query entirely:
SELECT DISTINCT * WHERE {
?carManufacturer dbpedia-owl:product dbpedia:Automobile;
dbpprop:locationCountry "France"@en.
} LIMIT 100
