So, it works. I suscribe to this list 'cause I develop a RDF import/export function for jgraphpad. And I have a problem ; I don't find the way to change a...
Nico, An RDF model is a set of statements so to make a change, you remove the old statement and add the new statement: Statement s1 = the statement for...
Carsten, This isn't a Jena issue specifically - merging models in RDF means just putting all the statements together. There isn't a special case for ...
Hi Peter, You are right that there is no direct support for qualified cardinality restrictions at the moment in the main ontology API. Although the ontology is...
I am adding triples from many different sources to a "database" model. to remove a set of triples at a later moment, I "tag" them using reification. how i do...
... OKAY, thanks, but how to create a statement ? I know how to get the statements from a model, but how to create one from nothing ? I obligatorily have to...
Nico, The way to create a statement is to use the operation Model.createStatement From the javadoc for Model: public Statement createStatement(Resource s, ...
... I get your point, but don't you think, that having a container with 2 rdf:_2 properties is against the semantics of a container? I see, that merging...
leo, i'm not sure what you mean by "sticky" (for reifier.standard). do you mean, the reification is removed (model.removeReification succeeds) but the...
Hi Ian, thank you very much for your help. Because of your last message I checked the List-Syntax and you are right. I hope that my problem wasted not too much...
Hi Thorsten, I encourage you to report this problem to the OilEd developers. It has been around for a while, so there may be a fixed version of the tool. If...
Hi Ian, I was looking at the class hierarchy example distributed with Jena-2.0 and I noticed that you decided to filter the restrictions in the rootClasses ...
Hi Fede, That's true, but the commentary says (index.html): This sample illustrates the process of generating a simple textual rendering of the class hierarchy...
... I have some statements in model A and reify them in A. then I copy A into B using b.addAll(a) then i try to delete the statements and the reifications from...
... Ah, in that case the problem/confusion can't lie with the database code but must be with the SimpleReifier that handles reification for MemModels. Chris,...
I have a simple owl ontology, and I want to write a java method that will verify that instance data doesn't violate a cardinality constraints. So I am...
Hi Gus, When you say "class C has a cardinality constraint", I guess you mean something like "C is a sub-class of a restriction on some property p with max/min...
the current implementation of ModelRDB.listStatements() reads the entire (database) model into main memory and then iterates over the resulting object. this...
Are you just considering datatype properties (i.e. counting literal values) or also considering ObjectProperties? For ObjectProperties then your approach is...

Can you help me? Where do you find ( in the jena 2 ) this example? I'm doing a browser for Ontology and the core is just the extract of Ontology class...
chintan, Any luck with this? I managed to load "nciOncology.owl" successfully with Jena 2.0 into MySQL (4.0.14b / small configuration, JDBC client 3.0.8 on ...

I have the same ontology, export in owl or daml+oil language. If I use the example code in jena2 to describe class I have a very different results If I read...
... But wouldn't that fail on a class where there is an additional subclassOf due to an IntersectionOf... like the one I have pasted below. What if I have a...
... Interesting, but I am not sure where/how the unique names comes into it. I do plan to distinguish individual instances (by unique combinations of several...
Hi Antonio, Don't forget that the sample program for showing the class hierarchy is *just an illustrative example of the API*, not a user tool. Without seeing...
