Hi!, I'm doing the following query in a sparql endpoint, and it works:
PREFIX movie: <http://data.linkedmdb.org/resource/movie/film>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX dc: <http://purl.org/dc/terms/>
SELECT ?resource ?id WHERE {
?resource movie:id ?id .
FILTER (?id = 72) .
}
but if i add genre, it doesn't work;
PREFIX movie: <http://data.linkedmdb.org/resource/movie/film>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX dc: <http://purl.org/dc/terms/>
SELECT ?resource ?id ?genero WHERE {
?resource movie:id ?id .
?resource movie:genre ?genero .
FILTER (?id = 72) .
}
With "this doesnt't work" i mean, it works, but it doesn't find anything.
The same happens for every attribute of "movie" type in page of
LinkedMDB<http://data.linkedmdb.org/page/film/2045>here , for some
reason i can't select them, i'm doing anything wrong?
Bye
You have
movie: <http://data.linkedmdb.org/resource/movie/film>
which is different.
so movie:id is
<http://data.linkedmdb.org/resource/movie/filmid>
and movie:genre is
<http://data.linkedmdb.org/resource/movie/filmgenre>
You meant:
movie: <http://data.linkedmdb.org/resource/movie/>
then
movie:filmid
movie:genre
