I figured out that the validation error was not only caused by the fact that the ontology is using OWL2 parts. Additionally, the way of creating the literal was wrong: model.createTypedLiteral(30.0, XSDDatatype.XSDfloat); This will create a double type. Changing this to the following made it work: model.createTypedLiteral(new Float(30.0), XSDDatatype.XSDfloat);
Another question: if you are saying, jena is not supporting OWL2. Is this limited to the reasoner only or to jena in general? Would it be possible to use my original ontology with an external reasoner that supports OWL2?
