如何添加对象属性与耶拿？特殊格式

你好，我想在这两个人之间添加一个对象属性。我也在代码中拥有对象属性，而个体在本体中。只需要使用属性连接它们。个人在代码中看起来像这样，我的问题是我从来没有使用这个“描述”标签来处理这个本体。如何添加对象属性与耶拿？特殊格式

我已经尝试过使用这段代码，但getters给了我null值。通过名称获取两个人，获取对象属性并将其添加到模型中。

Individual doc = model.getIndividual("n6356"); 
Individual ref = model.getIndividual("n6399"); 
ObjectProperty cites = model.getObjectProperty("http://purl.org/ontology/bibo/cites"); 
model.add(doc,cites,ref);

你有什么进展吗？ –

RDF中的资源是空白节点或URI节点。你的个人恰巧是IRI节点，所以你需要找回它们的方式有：

Individual doc = model.getIndividual("http://vivo.iu.edu/individual/n6356"); 
Individual ref = model.getIndividual("http://vivo.iu.edu/individual/n6399");

如果你打算做了很多这方面，它可能是有意义的事：

final String NS = "http://vivo.iu.edu/individual/"; 
Individual doc = model.getIndividual(NS+"n6356"); 
Individual ref = model.getIndividual(NS+"n6399");

如果你不保存你的模型在内存中，不要忘记写出来。

final String NS = "http://vivo.iu.edu/individual/"; 
Individual doc = model.getIndividual(NS+"n6356"); 
Individual ref = model.getIndividual(NS+"n6399"); 
ObjectProperty cites = model.getObjectProperty("http://purl.org/ontology/bibo/cites"); 
model.add(doc,cites,ref).write(new FileOutputStream(new File("rdf/myRDFFile.owl"));
