Hi Sorin, thanks for your fast reply. I already tried your suggestion as well as this one:
@prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> . [] ja:loadClass "com.hp.hpl.jena.tdb2.TDB2" . tdb:DatasetTDB2 rdfs:subClassOf ja:RDFDataset . tdb:GraphTDB rdfs:subClassOf ja:Model . Both lead to the same error as described in the initial post (org.apache.jena.assembler.exceptions.NoSpecificTypeException: the root https://km-ps.com/model/data/myDataset has no most specific type that is a subclass of ja:Object) Best regards, Johannes -----Ursprüngliche Nachricht----- Von: Sorin Gheorghiu <[email protected]> Gesendet: Mittwoch, 25.
