owl-api issue using swrl api and openllet #47

Closed SamanthaBandini closed 6 years ago

SamanthaBandini commented 6 years ago

I'm trying to use owl-api (v5), swrl-api and openllet in the same project, using NetBeans as IDE. There's no way to make them work together, importing one causes the other to stop "working". I think there is a problem with dependencies but I can't figure it out.

I have tried in different ways, such as:

  1. using Gradle: (see build.gradle.txt [Note: I added the .txt to attach it here])
  1. using Maven: (see pom.xml.txt [Note: I added the .txt to attach it here])
    • set dependencies
    • when there were problems in resolving dependencies I manually installed it from jar using 'Manually install artifacts' from Netbeans

Both method works, as I can see all classes of each package, the problem is that in both ways I get stuck with exceptions like those listed below.

Running this code:

      try {
           /* PART 1 - OWL API - Retrieve information from ontology */
            ontology = manager.loadOntologyFromOntologyDocument(filein);
            IRI iri = ontology.getOntologyID().getOntologyIRI().get();
            IRI remoteIRI = IRI.create(Constants.ONTOLOGY_IRI);
            manager.getIRIMappers().add(new SimpleIRIMapper(remoteIRI, iri));
            //Retrieve all organizations and put in in manufacturers model
            reasoner = openllet.owlapi.OpenlletReasonerFactory.getInstance().createReasoner(ontology);
            factory = manager.getOWLDataFactory();
            final OWLClass Organization = factory.getOWLClass(IRI.create(ORGANIZATION_IRI));
            for (OWLNamedIndividual ind : reasoner.getInstances(Organization, false).getFlattened()){
                this.manufacturers.add(new PairItem(ind.getIRI(),ind.getIRI().getShortForm()));
            };
            //Init DONE, manufacturers retrieved

        /* PART 2 - RULE WITH SWRL */
        //Trying to instanciate the rule engine
            SWRLRuleEngine ruleEngine;
            ruleEngine = SWRLAPIFactory.createSWRLRuleEngine(ontology);
            System.out.println("Loaded classes");
            //SWRLAPIRule rule = ruleEngine.createSWRLRule("MY_RULE");
            //ruleEngine.infer();

        } catch (OWLOntologyCreationException ex) {
            Logger.getLogger(Model.class.getName()).log(Level.SEVERE, null, ex);
        }

Trying the test with Maven:

I tried 'PART 1' and 'PART 2' separately in different projects and both worked.

Thanks in advance.

I'm guessing that they are using a different version of the OWLAPI.

Try the following:

mvn dependency:tree -Dverbose

Thanks for the reply. As you said, the're using different owlapi versions; protégé components use owlapi 4 and openllet uses owlapi 5. I solved this using the release of Pellet reasoner compatible with owlapi 4 (https://github.com/ignazio1977/pellet).
