jena限定合格證書限制名單資源

我是jena圖書館的新成員，希望列出合格證書限制的所有資源，屬性，數據類型。jena限定合格證書限制名單資源

我的限制：

... 
<rdfs:subClassOf> 
    <owl:Restriction> 
    <owl:onProperty   rdf:resource="http://purl.oclc.org/NET/ssnx/ssn#sensingMethodUsed"/> 
    <owl:onClass rdf:resource="http://purl.oclc.org/NET/ssnx/ssn#Sensing"/> 
    <owl:qualifiedCardinality rdf:datatype="http://www.w3.org/2001/XMLSchema#nonNegativeInteger">1</owl:qualifiedCardinality> 
    </owl:Restriction> 
</rdfs:subClassOf> 
<rdfs:subClassOf> 
    <owl:Restriction> 
    <owl:onProperty rdf:resource="http://purl.oclc.org/NET/ssnx/ssn#featureOfInterest"/> 
    <owl:onClass rdf:resource="http://purl.oclc.org/NET/ssnx/ssn#FeatureOfInterest"/> 
    <owl:qualifiedCardinality rdf:datatype="http://www.w3.org/2001/XMLSchema#nonNegativeInteger">1</owl:qualifiedCardinality> 
    </owl:Restriction> 
</rdfs:subClassOf> 
...

所需的字符串輸出：

qualcard sensingMethodUsed nonNegativeIteger 1 Sensing       
qualcard featureOfInterest nonNegativeIteger 1 FeatureOfInterest

請可有一個人幫我請。

該片段顯示它是OWL2本體。 Jena僅支持OWL1（請參閱包org.apache.jena.ontology）。但作爲選項，您可以使用ru.avicomp.ontapi.jena.model.OntGraphModel從ONT-API，這是org.apache.jena.ontology.OntModel但對OWL2規格完全模擬。這是基於apache-jena的庫。

一個例子：

public static void main(String ... args) { 
    // build model with qualified exact cardinality object property restrictions: 
    OntGraphModel m = OntManagers.createONT().createOntology().asGraphModel(); 
    m.setNsPrefixes(PrefixMapping.Extended); 

    OntNOP op1 = m.createOntEntity(OntNOP.class, "http://purl.oclc.org/NET/ssnx/ssn#sensingMethodUsed"); 
    OntClass c1 = m.createOntEntity(OntClass.class, "http://purl.oclc.org/NET/ssnx/ssn#Sensing"); 
    OntNOP op2 = m.createOntEntity(OntNOP.class, "http://purl.oclc.org/NET/ssnx/ssn#featureOfInterest"); 
    OntClass c2 = m.createOntEntity(OntClass.class, "http://purl.oclc.org/NET/ssnx/ssn#FeatureOfInterest"); 

    OntClass clazz = m.createOntEntity(OntClass.class, "http://example.com#clazz"); 
    clazz.addSubClassOf(m.createObjectCardinality(op1, 1, c1)); 
    clazz.addSubClassOf(m.createObjectCardinality(op2, 1, c2)); 
    m.write(System.out, OntFormat.RDF_XML.getID()); 

    // printing: 
    System.out.println(); 
    m.ontObjects(OntCE.ObjectCardinality.class).forEach(c -> { 
     String datatype = Stream.of(OWL.qualifiedCardinality, OWL.cardinality) 
       .map(p -> c.objects(p, Literal.class)) 
       .flatMap(Function.identity()) 
       .map(Literal::getDatatypeURI) 
       .map(m::shortForm) 
       .map(s -> s.replaceAll("^.*:", "")) 
       .findFirst().orElse(null); 
     int cardinality = c.getCardinality(); 
     String onClass = Optional.ofNullable(c.getValue()).map(Resource::getLocalName).orElse(null); 
     String onProperty = c.getOnProperty().getLocalName(); 
     System.out.printf("qualcard %s %s %d %s%n", onProperty, datatype, cardinality, onClass); 
    }); 
}

輸出這個例子：
