My two cents for Virtuoso 07.20.3214
This query does not work
###################################################
SELECT distinct ?class {GRAPH <http://dbpedia.org> {
?class rdfs:subClassOf* ?superclass.
FILTER (?superclass= <http://dbpedia.org/ontology/Actor>)
}}
###################################################
but this query works (just changing the position of the graphname
using a different syntax)
###################################################
SELECT distinct ?class FROM <http://dbpedia.org> {
?class rdfs:subClassOf* ?superclass.
FILTER (?superclass= <http://dbpedia.org/ontology/Actor>)
}
###################################################
