Olá, estou com um problema para importar um arquivo .owl
Ja importei as bibliotecas necessarias e retirei o exemplo direto do http://owlapi.sourceforge.net/

Mas aparece esse erro:

Out 29, 2012 3:06:52 PM uk.ac.manchester.cs.owl.owlapi.ParsableOWLOntologyFactory canLoad

Você já tentou colocar as barras invertidas :

Allan_Barcelos 29 de out. de 2012

Sim, quando coloco as barras invertidas da este erro:

este arquivo ODomJurBr-RAC.owl existe ? na partição do dropbox , certo ?

Qual é o seu SO ? faça um teste colocando 02 barras

F://Dropbox//experimento_proposta_dissertacao_denis//Eclipse_Projeto//OWLProj//Ontology//ODomJurBr-RAC.owl

Allan_Barcelos 29 de out. de 2012

Este arquivo existe em uma pasta do dropbox dentro do computador.
Ja tentei todas as combinações de barra, mas nada resolve
Até fiz debug, e o OWLOntologyFactory estava la, é estranho o stack de erro dizer que não foi encontrado

Aleksandro 29 de out. de 2012

eu me recordo que havia um bug de URI no eclipse , não me recordo qual era a versão …vc esta usando eclipse em que versão ?

Allan_Barcelos 29 de out. de 2012

To usando:

Eclipse Java EE IDE for Web Developers.

Version: Juno Release
Build id: 20120614-1722

É o ultimo lançado eu acho, por que ?

Acho que era o helios que tinha um bug deste tipo … cara você já tentou mover este arquivo para raiz por exemplo c:\ e apontar para este caminho, outra coisa …

Allan_Barcelos 29 de out. de 2012

Ja, mas não resolve em nada.

Tentei um monte de coisa, até tentei usar o Jena, mas com ele da MalformedURLException (com o mesmo endereço do projeto com a owl api)

Aleksandro 29 de out. de 2012

Estava dando uma olhada na net …será que esta IRI não aceita apenas http:// … será que localmente não é outra coisa tipo URI …não olhei a documentação …da uma olhada no javadoc e veja senão tem algo que faça acesso local … achei este link aqui …

http://www.people.lu.unisi.ch/fornaran/ontology/OntologyDALT09.java.txt

da olhada …

Allan_Barcelos 30 de out. de 2012

Bah… até tentei, mas o código:

OWLOntology ontology = manager.loadOntologyFromPhysicalURI(URI.create(PHYSICAL_URI));
        System.out.println("Loaded " + ontology.getURI());

Este com erro e pede um cast, mas não resolve o problema

A ideia é legal, ja tentei uma parecida

public void testOntologyLoading() throws Exception {
    	IRI oDomJurBRRAC = IRI.create("ftp://[email removido]//minhaOntologia.owl");
    	OWLOntologyManager m = create();
    	OWLOntology head = m.loadOntologyFromOntologyDocument(oDomJurBRRAC);
    	assertNotNull(head);
    	StringDocumentTarget target = new StringDocumentTarget();
    	m.saveOntology(head, target);
    	m.removeOntology(head);
    	OWLOntology o2 = m.loadOntologyFromOntologyDocument(new StringDocumentSource(target.toString()));
    	assertNotNull(o2);
    }

Esta da erro de URL mal formada

E esta tambem:

public void shouldLoad() throws OWLOntologyCreationException {
    	// Get hold of an ontology manager
    	OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
    	// Let's load an ontology from the web
    	URL url = null;
    	URLConnection conn = null;
    	IRI iri = null;
    	try {
    		url = new URL("ftp://[email removido]//minhaOntologia.owl");
    		conn = url.openConnection();
    		conn.connect();
    		iri = IRI.create(conn.getURL());
    	} catch (MalformedURLException e) {
    		// TODO Auto-generated catch block
    		e.printStackTrace();
    	} catch (IOException e) {
    		// TODO Auto-generated catch block
    		e.printStackTrace();
    	} catch (URISyntaxException e) {
    		// TODO Auto-generated catch block
    		e.printStackTrace();
    	}
    	OWLOntology pizzaOntology = manager.loadOntology(iri);
    	System.out.println("Loaded ontology: " + pizzaOntology);
    }

Esta da erro ao achar o arquivo, não conecta ao FTP
Tentei com o Jena tambem, mas ele tambem não conecta no FTP, mesmo criando uma conexão remota

Não faço a minima ideia de como vou resolver isso

Aleksandro 30 de out. de 2012

OWLOntology ontology = manager.loadOntologyFromPhysicalURI(URI.create(PHYSICAL_URI));
        System.out.println("Loaded " + ontology.getURI());

Aqui qdo pediu o cast você diz que não resolve o problema , não entendi , envia o log quando você tentou desta maneira , pelo que percebi a URI você cria ela em algum local e depois recupera … envia o log de erro para dar uma olhada …

Allan_Barcelos 30 de out. de 2012

Tem erro de cast

OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
        OWLOntology ontology = manager.loadOntologyFromPhysicalURI(URI.create("ftp://[email removido]//minhaOntologia.owl"));  // Pede o cast para manager
        System.out.println("Loaded " + ontology.getURI()); // Pede cast para ontology

Ele pede o cast na linha infinitamente

OWLOntology ontology = ((Object) manager).loadOntologyFromPhysicalURI(URI.create("ftp://[email removido]//minhaOntologia.owl"));

E na outra linha

System.out.println("Loaded " + ontology.getURI());

Pede um cast que não é aceito

Eu consegui fazer carregar de um arquivo local, mas não consigo do FTP, fica aparecendo o erro abaixo:

Allan_Barcelos 30 de out. de 2012

Consegui com uma coisa absurdamente facil.

o problema da conexão com o ftp era a senha que faltava no caminho.

ftp://ontologias:[email removido]/minha.owl

E consegui tambem para carregar arquivo do computador

Valeu ae
