我有一个用 protege 4.2 创建的 owl 文件。当我使用 Jena 添加一些实例时，Jena 更改了文件结构，但文件扩展名保持不变（.owl），该文件在 protege 中是可读的，但有一些错误。任何人都知道我的代码的问题在哪里？

因为在使用 Jena 进行编辑后，查询的结果有点奇怪。

例如，在使用 Jena 进行编辑之前

 <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");


}

model.writeAll(p, "RDF/XML", null);

试试漂亮的打印机“RDF/XML-ABBREV”。

但无论哪种方式，它都是相同的三元组，不同的写法，这才是最重要的。
