Is it possible, to query the ontology alongside a virtual graph? I built a test project (Data tables in PostgreSQL - Ontology and mappings in Protege/w Ontop Plugin), and while querying via the Ontop Sparql Tab works fine, the answers only include triplets from the VKG, but triplets from the ontology do not show up. I tried the same in graphDB with an ontop style repository to no avail.

Thank you in advance!

  • Please, try to set the following in your properties file: > ontop.enableFactExtractionWithTBox = true > ontop.queryOntologyAnnotation = true Have a look at https://ontop-vkg.org/guide/advanced/configuration – Peter Hopfgartner May 11 '23 at 14:55
