Hello,
I'm trying to get negated data with SPARQL (individuals of an ontology
that do not belong to a certain class), but I could not figure out how
to write the appropriate query therefore. It's working for object
properties and using FILTER NOT EXIST, but this one I can't manage.
Could you help me out here please?
The query should somehow look like this:
"PREFIX
ro:<http://www.semanticweb.org/ontologies/2012/4/test_ontology.owl#>
SELECT ?r WHERE NOT{?r a ro:RelatedRequirement}";
The NOT is just placed here to indicate that I want to get all
individuals that are NOT instances of the ontology class RelatedRequirement.
Thanks,
Katja
