Hi all. Thanks a lot for the help you have provided to me till now. Dear, I am presently facing a problem in use of Jena. Following is my problem. Problem: I...

Hi, I can already confirm that Joseki can handle cascaded queries properly and the behavior must be originating from somewhere else I don't know yet. Debuggung...
... What's the use case? It helps me to have context. I'd guess you are not processing the result model after execution but during building (production ...

Hi, is there a Java framework to wrap OWL/RDF into a Model (in MVC terms) in the way that Object-Relational Mapping wraps a relational database? Jena-based or...
Martynas, I had the same issue, and during a project wrote a simple binder. See http://code.google.com/p/jenabean. I'm looking for participants. The project...
HI, I'm developing an aplication using Jena and the Protege API, but I'm having a problem to get the individuals that have a certain property. ... property_A...
Hi everybody. I have the same owl model of the other posts, and in this model there is a class named "Elemento_conoscenza" that have three subclasses,...
Hello Eduardo, ... Have you declared property_A to be transitive? Because if you have, the reasoner will tell you that p_A( i_A, i_F ) is true without you...
... Yes. You need to use a model with an attached reasoner (e.g. OWL_MEM_MICRO_RULE_INF) and then your query will return the instances of the class and its...
Sorry, I think I made the wrong question... The questio is: How can I get the individuals related? Using Jena and/or Protege API... Lets say that I have...

Hello Chris, thank you for the quick answer. This makes things a little clearer to me. I learned two things. 1) it all depends 2) you don't have to do complete...
