Hi all,
I was wondering whats happening..
the following query returns only yago (root classes) when executed with the
browser (firefox)..
but when running the query with the jena sparql service... it also returns
opencyc concepts and some others (including "classes" that apparently doesnt
have subclasses)..
CONSTRUCT {
?y <http://www.w3.org/2000/01/rdf-schema#label> ?label
} WHERE {
?sub <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?y .
?y <http://www.w3.org/2000/01/rdf-schema#label> ?label .
OPTIONAL {?y <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?super} .
filter(!bound(?super))}
by the way.. if I also Include in the construct clause the subclasses of
?y.. ?sub <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?y
then jena cant parse the resulting xml... invalid chars..
CONSTRUCT {
?y <http://www.w3.org/2000/01/rdf-schema#label> ?label .
?sub <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?y
} WHERE {
?sub <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?y .
?y <http://www.w3.org/2000/01/rdf-schema#label> ?label .
OPTIONAL {?y <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?super} .
filter(!bound(?super))}
thanks for attention...
