我有一个使用protege 4.2创建的owl文件。当我使用Jena添加一些实例时,Jena会更改文件结构,但文件扩展名保持不变(.owl),文件可读时会出现一些错误。有人知道我的代码有什么问题吗?
因为使用Jena编辑后,sparql查询的结果有些奇怪。
例如,在使用Jena编辑之前
<owl:NamedIndividual rdf:about="&ontologies;thesis_ontology_1try#AM6">
<rdf:type rdf:resource="&ontologies;thesis_ontology_1try#ApplicationModel"/>
<hasID rdf:datatype="&xsd;string">20125157-d62b-45de-8809-84186c7169b5AM6</hasID>
<name rdf:datatype="&xsd;string">Gebäudemodell / Buildingmodel</name>
<hasContent rdf:resource="&ontologies;cpixml"/>
<hasLevelOfDetail rdf:resource="&ontologies;thesis_ontology_1try#4"/>
<hasDomain rdf:resource="&ontologies;thesis_ontology_1try#BIM"/>
<hasType rdf:resource="&ontologies;thesis_ontology_1try#Object"/>
<hasPhase rdf:resource="&ontologies;thesis_ontology_1try#SLCT"/>
<hasContent rdf:resource="&ontologies;thesis_ontology_1try#ifc"/>
</owl:NamedIndividual>
耶拿之后

这是代码
public static void main(String[] args) throws IOException {
InputStream in = FileManager.get().open("./src/thesis_ontology_1try.owl");
OntModel model = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MICRO_RULE_INF, null);
model.read(in, null);
in.close();
String NS = "http://www.semanticweb.org/thato/ontologies/2012/10/9/thesis_ontology_1try#";
OntClass ApplicationModel = model.getOntClass(NS + "ApplicationModel");
Individual dom = model.getIndividual(NS + "RFP");
Individual pha = model.getIndividual(NS + "SLCT");
Individual lev = model.getIndividual(NS + "3");
Individual new1 = model.createIndividual(NS + "new1", ApplicationModel);
ObjectProperty domain = model.createObjectProperty(NS +"hasDomain");
ObjectProperty phase = model.createObjectProperty(NS +"hasPhase");
ObjectProperty lod = model.createObjectProperty(NS +"hasLevelOfDetail");
model.add(new1, domain, dom);
model.add(new1, phase, pha);
model.add(new1, lod, lev);
PrintStream p= new PrintStream("./src/thesis_ontology_1try.owl");
model.writeAll(p, "RDF/XML", null);
p.close();
System.out.println("Done");
}
}
答案 0 :(得分:2)
model.writeAll(p, "RDF/XML", null);
尝试“漂亮的打印机”RDF / XML-ABBREV。
但无论哪种方式,它都是相同的三元组,用不同的方式写出来,这才是最重要的。
