Hi Dave:
Thanks for the response. Here is my code:
public class testTDB {
public static void main(String[] args) {
String directory = "./tdb";
Dataset dataset = TDBFactory.createDataset(directory);
Model tdb = dataset.getDefaultModel();
String source = "/Users/adeebnoor/Downloads/Ontologies/umls.trig";
FileManager.get().readModel(tdb, source, "TriG" );
tdb.close();
dataset.close();
}
I got this error:
Exception in thread "main" com.hp.hpl.jena.shared.NoReaderForLangException:
TriG
at com.hp.hpl.jena.rdf.model.impl.RDFReaderFImpl.getReader(
RDFReaderFImpl.java:100)
at com.hp.hpl.jena.rdf.model.impl.ModelCom.read(ModelCom.java:276)
at com.hp.hpl.jena.util.FileManager.readModelWorker(FileManager.java:403)
at com.hp.hpl.jena.util.FileManager.readModel(FileManager.java:342)
at ddid.testTDB.main(testTDB.java:19)
Then I remove the Trig string pramater from the Filemangager method:
FileManager.get().readModel(tdb, source );
and the program seems to be running and taking the whole memory but I got
this warning message:
03:37:31 WARN riot :: Only triples or default graph
data expected : named graph data ignored
After waiting the program to finish I check it the TDB and there was
nothing on it.
what do you think.
Thanks
