    // "graph" is a CommonsRDF graph 
    Graph graph = JenaCommonsRDF.fromJena(jGraph);

    // Add to CommonsRDF Graph
    RDFTermFactory rft = new RDFTermFactoryJena();
    graph.add(rft.createIRI("http://example/s2"), rft.createIRI("http://example/p2"), rft.createLiteral("foo"));
    System.out.println("==== Write CommonsRDF graph\n");
    graph.getTriples().forEach(System.out::println);

    System.out.println("\n==== Write Jena graph directly\n");
