Hi all, I am relative new to the SPIN API and I am facing some basic problems:
I want to apply a spin:constraint based on a existing template to a class. In the following lines you see how I get the template and bind the arguments. Template template = SPINModuleRegistry.get().getTemplate( "http://spinrdf.org/spl#ObjectCountPropertyConstraint";, ontModel); com.hp.hpl.jena.query.Query arq = ARQFactory.get().createQuery((Construct)template.getBody()); QueryExecution qexec = ARQFactory.get().createQueryExecution(arq, ontModel); QuerySolutionMap arqBindings = new QuerySolutionMap(); arqBindings.add(SPIN.THIS_VAR_NAME, informationItem); arqBindings.add("property",describesSituation); arqBindings.add("maxCount",ResourceFactory.createTypedLiteral("2" ,XSDDatatype.XSDinteger)); arqBindings.add("minCount",ResourceFactory.createTypedLiteral("2" ,XSDDatatype.XSDinteger)); qexec.setInitialBinding(arqBindings); Now, I execute the query: Model cm = qexec.execConstruct(); qexec.close(); cm.write(System.out); And I see in my console the following constraint violation triple: <rdf:Description rdf:nodeID="A0"> <j.0:violationPath rdf:resource="http://purl.org/biotop/btl2.owl#represents"/> <j.0:violationRoot rdf:resource="http://www.semanticweb.org/martinezc/ontologies/2013/6/shn2.owl#shn:InformationItem"/> <rdf:type rdf:resource="http://spinrdf.org/spin#ConstraintViolation"/> </rdf:Description> My problem is what to do next. I would like to show the error message, so I tried the following: // Run all constraints List<ConstraintViolation> cvs = SPINConstraints.check(ontModel, null ); System.out.println("Constraint violations:"); for(ConstraintViolation cv : cvs) { System.out.println(" - at " + SPINLabels.get().getLabel(cv.getRoot()) + ": " + cv.getMessage()); } I do no get any result. I tried to add the constraint violation triple to the ontModel, but I do not get any result printed anyway. Is there an intermediate step required to add the spin:constraint to the class, that I am missing?
