Thanks Chris! Can you please go a bit more in detail with the cheating assembler you mentioned? A quick and easy solution will be ok for my first prototyp. ...

Hi All, I've two functions that I don't know how to code with Jena. first I create a ontmodel like: OntModel model = ModelFactory.createOntologyModel ...
I think I understand what you mean: The application builds the union and prints it to a file lets say every hour or so. Joseki takes this file and provides the...

Hi there, If you first created a ModelRDB you could name that and then pass the ModelRDB into your createOntologyModel call instead of null. In terms of...
If you can update a DB (or the quicker SDB) via your Jena code, then Joseki can be linked to that and will always query the latest state of the Database...
... Depends what you mean by name - do you mean the location where you will store it? The default namespace? The name by which the model is known is some...
Thanks for your answer James. The thing is I don't use Jena to manipulate the models. My jena-based application only merges two ontologies (One is a file that...

everyone, I am studying jena now and need some help. first problem: I think, when a owl ontology is loaded in a OntModel without inference, it still be a tree....
... It's a graph. It might /happen/ to be a tree, for some ontologies, but it is a graph. Consider: my:A a owl:Class. my:B a owl:Class. my:C rdfs:subClassOf...
... If you want to work with ontologies using RDFS or OWL (only OWL has restrictions; RDFS doesn't), then you should try the OntModel API and its friends...
Hi Dave, I have used Protege to develop an OWL disability ontology for the disability portal that I am developing. I am also using Jena as the Java API for...
Hi, My apologies for replying late. I am just back from my presentation. And good news..patch works !!! I've used the patch file and built sdb.jar. It works...
... You can take an RDF model and simply read into it the RDFS document as well. Or you could treat it all as OWL (full) and put an owl:import statement in...

Thank you so much for the response. I want to populate the ontology I have created with information that is already contained in database in order to make this...

... Thanks, sorry I took a while to get back to this. I basically did as you suggested, but weeding out a few unwanted statements. I was a bit surprised to...
... Correct. The rdfs:subClassOf is reflexive. We found it more convenient if the transitive reasoner included this, especially when dealing with cycles. If...
Sorry but this is still not clear. Is your PostgreSQL database (a) a Jena database containing RDF data or (b) a "normal" database with your own schema. In the...
... It *is* an OWL file, OWL is serialized as RDF, it is just slightly differently expressed from normal. If you use "RDF/XML-ABBREV" in the writeAll statement...
