Hello !
A question.
How to use owl-reasoner with jena ?
practical
owl model: ("beatle eat tree")

</insect>

source: (OK ?)
String fileOnto = "C:\\data\\test.owl";
String fileRules = "demo.rules";
OntModelSpec spec = new OntModelSpec(OntModelSpec.OWL_DL_MEM);
Resource configuration = modelRes.createResource();
configuration.addProperty(ReasonerVocabulary.PROPruleMode, "hybrid");
configuration.addProperty(ReasonerVocabulary.PROPruleSet, "demo.rules");
GenericRuleReasoner reasoner = (GenericRuleReasoner)
GenericRuleReasonerFactory.theInstance().create(configuration);
spec.setReasoner(reasoner);
OntModel model = ModelFactory.createOntologyModel(spec);
model.read( in, fileOnto );
model.prepare();
model.write(System.out);
Questions:
- Is the source to change ?
- OntModelSpec.OWL_DL_MEM oder OntModelSpec.OWL_MEM ?
- What rules for example can define ?
Thank you.
greeting
Michael
