Hello, I'm a little confused so I was hoping someone could clarify something for me. I want to use DARQ (when it is updated) to work as my processor for Joseki...
Dear Jena Newsgroup I am working on an OWL ontology which stores rules , antecedents and consequents. There are 3 classes : Antecedent , Consequent and Rule. ...
... No, it's not negation as failure. For the backward chainer it is negation over the EDB predicates or rather negation over the input data and is thus...
... For forward inference then the deduce triples get asserted into the deductions model so I think you should be able to place a listener on that. For...
... Some uses of the rule system and the DIG interface can produce result sets which depend upon how bound the query is, which breaks the assumptions made by...
... Yes -- the chap who wrote the GraphEvents class was being an idiot. I will castigate him. -- Yes, Virginia, there is a second Jena user conference:...
... He has been castigated. The CVS now has a version of GraphEvents which sports getContent() and getTitle(). And test cases. (No, I don't know why it didn't...

Hello, i can't find any information about this method : FileManager.addCacheModel() does it help to handle some models like 'named graph' ? and then a model...
FileManager.removeCacheModel(String, Model) enters a model into the file manage cache under the name given. If asked to read from that name, the model will be...

Hello, I am using Jena and Joseki and I am having some very strange problems. These are in my testcases. These use Jena directly, for some things and for ...
Hello, I am using Jena for my MSc Project and wish to know how Jena supports database transaction. I am new to Jena and still experimenting with it. I =n my...
... The Model interface supports begin/commit/abort operations for control such transactions. Dave -- Hewlett-Packard Limited Registered Office: Cain Road,...
... Note that the operations are applied to a Model, but affect all the Models that share the same database connection. (Which is what you get if you use an...
... Pretty much. Jena is a general purpose RDF API (that means RDF data, not just ontologies) plus an OWL API, plus SPARQL processor, reasoning support,...
Hi, I seem to be missing something here. I create an ontology model, and then add individuals to this model. I then create an inferred model, but when I try...
