Thanks Anday:
here is my new code and I am still getting this warning message:
04:37:02 WARN riot :: Only triples or default graph
data expected : named graph data ignored
String directory = "/Users/adeebnoor/Desktop/Desktop/DDID/UMLStdb";
Dataset dataset = TDBFactory.createDataset(directory);
String source = "/Users/adeebnoor/Downloads/Ontologies/umls.trig";
Model m = ModelFactory.createDefaultModel() ;
System.out.println("start loading");
RDFDataMgr.read(m, source);
System.out.println("done loading");
m.close();
dataset.close();
Am I doing something wrong?
