我如何向我的 Jena 本体添加一些三元组？

I have instance1 of class1 and instance2 of class2。我也定义了HasName(object property)在我的本体论中。现在，我如何添加三重（instance1 HasName instance2）到 jena 的本体论？

这是一种无需处理中间的方法Statements.

// RDF Nodes -- you can make these immutable in your own vocabulary if you want -- see Jena's RDFS, RDF, OWL, etc vocabularies
Resource class1 = ResourceFactory.createResource(yourNamespace + "class1");
Resource class2 = ResourceFactory.createResource(yourNamespace + "class1");
Property hasName = ResourceFactory.createProperty(yourNamespace, "hasName"); // hasName property

// The RDF Model
Model model = ... // Use your preferred method to get an OntModel, InfModel, or just regular Model

Resource instance1 = model.createResource(instance1Uri);
Resource instance2 = model.createResource(instance2Uri);

// Create statements
instance1.addProperty(RDF.type, class1); // Classification of instance1
instance2.addProperty(RDF.type, class2); // Classification of instance2
instance1.addProperty(hasName, instance2); // Edge between instance1 and instance2

您还可以以构建器式模式链接其中一些调用。

Resource instance2 = model.createResource(instance2Uri).addProperty(RDF.type, class2);
model.createResource(instance1Uri).addProperty(RDF.type, class1).addProperty(hasName, instance2);
