Data Modeling and Import

Creating and Manipulating RDF Data

Creating RDF Models:

import org.apache.jena.rdf.model.Model;
import org.apache.jena.rdf.model.ModelFactory;
import org.apache.jena.rdf.model.Resource;
import org.apache.jena.rdf.model.Property;

public class JenaExample {
    public static void main(String[] args) {
        Model model = ModelFactory.createDefaultModel();
        String ns = "http://example.org/";
        Resource alice = model.createResource(ns + "Alice");
        Property knows = model.createProperty(ns + "knows");
        Resource bob = model.createResource(ns + "Bob");
        model.add(alice, knows, bob);

        // Print the model in RDF/XML format
        model.write(System.out, "RDF/XML");
    }
}

Loading RDF Data:

model.read("path/to/file.rdf");
