Chris,
the current approach to that is through the Tinkerpop Sail
implementation on top of Neo4j, see
https://github.com/tinkerpop/blueprints/wiki/Sail-Ouplementation.
Basically, you do
Sail sail = new GraphSail(new Neo4jGraph('rdf-store'));
SailConnection sc = sail.getConnection();
ValueFactory vf = sail.getValueFactory();
sc.addStatement(vf.createURI("http://tinkerpop.com#1";),
vf.createURI("http://tinkerpop.com#knows";),
vf.createURI("http://tinkerpop.com#3";),
vf.createURI("http://tinkerpop.com";));
sc.addStatement(vf.createURI("http://tinkerpop.com#1";),
vf.createURI("http://tinkerpop.com#name";), vf.createLiteral("marko"),
vf.createURI("http://tinkerpop.com";));
sc.addStatement(vf.createURI("http://tinkerpop.com#3";),
vf.createURI("http://tinkerpop.com#name";), vf.createLiteral("josh"),
vf.createURI("http://tinkerpop.com";));
System.out.println("get statements: ?s ?p ?o ?g");
CloseableIteration<? extends Statement, SailException> results =
sc.getStatements(null, null, null, false);
while(results.hasNext()) {
System.out.println(results.next());
}
System.out.println("\nget statements: http://tinkerpop.com#3 ?p ?o ?g");
results = sc.getStatements(vf.createURI("http://tinkerpop.com#3";),
null, null, false);
while(results.hasNext()) {
System.out.println(results.next());
}
HTH? Let me know if you need help setting this up!
