What have you tried so far that _didn't_ work for you? This code
creates a Restriction on a property and the model contains just three
statements. There's no OWL file.

import com.hp.hpl.jena.ontology.OntModel;
import com.hp.hpl.jena.ontology.OntModelSpec;
import com.hp.hpl.jena.ontology.OntProperty;
import com.hp.hpl.jena.rdf.model.ModelFactory;
public class RestrictionExample {
public static void main(String[] args) {
final OntModel model = ModelFactory.createOntologyModel(
OntModelSpec.OWL_DL_MEM );
final OntProperty p = model.createOntProperty( "http://example.org/p" );
model.createRestriction( p );
model.write( System.out, "TTL" );
}
}
