Is it enough to load the Schema triples along with my triples? I thought I would need some of those
"inference" or "reasoner" extensions.
No need to load
Either unionDefaultGraph
Or
SELECT ?entity
WHERE {
?entity rdf:type ?T .
GRAPH <schema> { ?T rdfs:subClassOf* :CreativeWork }
}

Assuming you have the Schema vocab loaded in the same dataset (or graph),
the following should work
SELECT ?entity
WHERE {
?entity rdf:type/rdfs:subClassOf* :CreativeWork
}

Let's say I have a node of type schema:Book and one of type
schema:VideoGame. In the Schema vocabulary, both are subclasses of
schema:CreativeWork.
Can somebody please give me a hint how to query Fuseki for
schema:CreativeWork in order to retrieve both types?
