Examples with Property org.apache.jena.rdf.model.Property used on opensource projects

Example 1 with Property

use of org.apache.jena.rdf.model.Property in project jena by apache.

the class TestConnection method connection_1.

@Test
public void connection_1() {
    SDBConnection conn1 = SDBFactory.createConnection(conn);
    Store store1 = StoreFactory.create(storeDesc, conn1);
    // Reset
    store1.getTableFormatter().format();

    Store store2 = StoreFactory.create(storeDesc, conn2);
    Model model1 = SDBFactory.connectDefaultModel(store1);
    Model model2 = SDBFactory.connectDefaultModel(store2);
    Resource s = model1.createResource();
    Property p = model1.createProperty("http://example/p");
    // These are autocommit so two stores should be OK (but not a good design paradigm)
    model1.add(s, p, "model1");
    model2.add(s, p, "model2");
    assertEquals(2, model1.size());
    assertEquals(2, model2.size());
    assertTrue(model1.isIsomorphicWith(model2));
}
