Hi Jena team, While trying to track down some performance problems, I've narrowed in on the following: Statement.getStatementProperty() seems to be very slow....
Hi, I am using an OWL ontology to create a security ontology for marking up data with its security level. I create instances of classes in the ontology and use...
Thanks Dave, I shall check that out. Another doubt I have is, if I have an rdfs schema file in which I declare classes and then I have an OWL file in which I...
