Class Bean2RDF

public class Bean2RDF
extends Base

Converts a simple java bean to RDF, provided it's annotated with Namespace. To make a bean persitable by jenabean, you are merely required to add the Namespace annotation. By default public bean properties are converted to rdf properties by appending "has" and proper casing the property name. For example, a bean with methods getName() and setName() would result in the RDF property "hasName", with the namespace given in the classes Namespace annotation.

The default behavior for rdf property naming is overridden by using the RdfProperty annotation along with the getter method. The value supplied to the RdfProperty annotation is taken as the full RDF property URI.

The bean itself is typed using the Namespace annotation along with the bean name, for example, Book.class with namespace "http://example.org/" becomes rdf type "http://example.org/Book".

Here's a simple example of a bean that's ready to be saved:

 
 package org.example;
 import thewebsemantic.Id;
 public Book {
    private String name;
    public void setName(String s) { name=s;}
    @Id
    public String getName() {return name;}
 }
