I found the solution. The key is : val MaryTojohnClaimOnto = model.createOntology(ontoName)
here is what i did: val ontoName = "http://www.people.usi.ch/okouyad/Mary_to_john_Claim_01.owl"; val model = ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM) val MaryTojohnClaimOnto = model.createOntology(ontoName) private val MaryRepoOntoPrefix = "http://www.people.usi.ch/okouyad/MaryRepositoryOntology.owl#"; private val payDeliverPrefix = "http://www.people.lu.unisi.ch/okouyad/PayDeliveryOntology.owl#"; model.setNsPrefix("", ontoName + "#") model.setNsPrefix("MaryRepoOnto", MaryRepoOntoPrefix) model.setNsPrefix("PayDelivery", payDeliverPrefix) private val indiv = model.createResource(MaryRepoOntoPrefix + "Lord_of_the_Ring") private val hasPriceProperty = model.createProperty(payDeliverPrefix + "hasPrice") indiv.addLiteral(hasPriceProperty, 15) //model.write(System.out); RDFDataMgr.write(System.out, model, Lang.TTL) Meanwhile i get this and i write it down: @prefix : <http://www.people.usi.ch/okouyad/Mary_to_john_Claim_01.owl#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix xsd: <http://www.w3.org/2001/XMLSchema#> . @prefix owl: <http://www.w3.org/2002/07/owl#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix PayDelivery: <http://www.people.lu.unisi.ch/okouyad/PayDeliveryOntology.owl#> . @prefix MaryRepoOnto: <http://www.people.usi.ch/okouyad/MaryRepositoryOntology.owl#> . MaryRepoOnto:Lord_of_the_Ring PayDelivery:hasPrice "15"^^xsd:long . <http://www.people.usi.ch/okouyad/Mary_to_john_Claim_01.owl> a owl:Ontology . I find it weird that the ontology triple comes at the end. If i create an analogue file with protege and loads it, and write it down, the ontology declaration triple get written at the beginning as everyone would expect. I think it is a code smell. Any idea ? is something going wrong ? -- Daniel Maatari Okouya Sent with Airmail From: Daniel Maatari Okouya Daniel Maatari Okouya Reply: [email protected] [email protected] Date: January 4, 2014 at 4:40:59 PM To: [email protected] [email protected] Subject: How to create a jena Model with a specific URI ? Hi, I would like to know how to create a Jena Ontology model with a given URI. all the example are about loading a model and getting the urL from it. I would like to do the contrary, create the model with a specific URI and save it with that URI. a.k.a with the rdfabout or owlOntology tag properly set with the URI that i want: the IRI/URI of my ontology Any help ? -- Daniel Maatari Okouya Sent with Airmail
