从本体创建 Java 类

发布于 2024-09-13 01:15:59 字数 571 浏览 4 评论 0原文

我有一个本体文件（RDF 格式），它表示我正在编写的应用程序中的实体。我正在使用 Jena，可以通过直接操作三元组来访问概念并创建/访问资源。

为了使事情变得更容易，我创建了一组 Java 类，每个类对应本体中的每种类型的资源，同时牢记它们的继承和属性。例如

public class Agent{
}

，

public class Person extends Agent{
  private String name;
}

如果本体包含两种类型的资源，Agent和Person，后者是前者的子类。

我意识到创建这些类的过程（以及提取它们的方法）非常单调。如果我在数据库上编写应用程序，我会使用 Hibernate 的配置文件并让它处理细节。

我的问题是：是否有一种工具可以将本体（在 RDF 文件中）作为输入，并创建一组代表本体中概念的 Java 文件，如上面的示例所示？（或者如果耶拿本身可以做到这一点，而我错过了一些东西）

谢谢。

原文

I have an ontology file (in RDF) which expresses the entities in the app that I am writing. I am using Jena, and can access the Concepts and create/access the resources by directly manipulating triples.

To make things easier, I created a set of Java classes, one for each type of resource in my ontology, keeping in mind their inheritances, and properties. E.g.

public class Agent{
}

and

public class Person extends Agent{
  private String name;
}

If the ontology contains two types of resources, Agent and Person, with the latter being a subclass of the former.

I realized that the process of creating these classes (and the methods to extract them) are very monotonous. If I was writing an application on databases, I would have used a config file for Hibernate and let it take care of the details.

My question is: Is there a tool available that will take an ontology (in an RDF file) as input, and create a set of Java files representing the Concepts in the ontology, as in the example above? (or if Jena itself can do this, and I am missing something)

Thanks.
