Hi Charlie, From: Charlie Abela [mailto:abcharl@...] ... I hadn't come across JTP before, but it looks pretty interesting. It looks like it might fit...
... I haven't no but it does sound interesting. Checking the web site I see it is a full first order theorem prover embedded in a modular framework - sounds...
Jena is a bit out my focus now, but I regularly quickly scan the daily digest. The topic "removing resource from a model" triggered something in me as I have...
Stefan, RDQL just queries a model at the RDF level - so, if I understand RDF properly, then properties like subClassOf are not transitive at the moment (RDF...
Several people have mentioned a desire to use the Jena RDB support with Oracle. I have now upload a set of patches to the sourceforge CVS repository which ...
I'm using Jena 1.3.0 and encountered that the property accessor for the 'range' property (prop_range()) fails on range statements defined with the daml:range...
Thorsten - Do you mean fails as in "throws an exception" or fails as in "doesn't give the right result"? As always, a code sample would really help to track...
Ian, it doesn't give the right result. Processing the following DAML fragment: <daml:Class rdf:ID="Class1"/> <daml:Class rdf:ID="Class2"/> <daml:Class...
Thanks Thorsten. I've fixed the problem and committed the code back to CVS. If you do an update from SourceForge, you can get the fix immediately. Otherwise,...
Hi Can anyone tell me whether this DAML code is correct: <rdfs:subClassOf> <daml:Restriction> <daml:onProperty rdf:resource="&process;#compon ents" /> ...

I don't know if I understand you very much, but what I think that your model means that your abstract class is a class that have a property component which...
Hi Charlie, I would say that this class expression defines a class of those things that have a 'components' property, the range of which is either a Query or a...
I want know if exists a method in "Jena" to know the properties of a specific class in a ontology. Example Person is a class Man is another class Person and...
how is the method or form to obtain the datatypeproperty for any Class example: <daml:DatatypeProperty rdf:ID="String"> <rdfs:comment> typerestriction is a...
Hi Douglas, One of the things I explicitly say in the release notes for the current DAML support is that it does not reason about restrictions. Don't think of...
Hi I am a new user to Jena. My question is: It is possible to read a DAML ontology file in Jena. How does Jena store all these DAML tags? Once this file is...
Hi Venkat, From the directory you unzipped Jena into, look at docs\DAML+OIL\daml-intro.html Also, see the com.hp.hpl.jena.daml.* classes in the Javadoc. ...
I'm using the ontology http://www.daml.org/2001/03/daml+oil.Using the method getDefineProperties for the class "Person" return me only the property "hasParent"...
If you read the ontology, hasFather is defined as a sub-property of hasParent. Given that no other constraints are placed on the domain of hasFather, *in this...
We are developing a datastore to hold information about features on a map display. Some that move and some that don't, the static ones we store the location as...
I understand your issue. The query primitives in the RDF API, are just that, primitive. More powerful operations are needed really, but I just don't know what...
I'm using OntoEdit to create an ontology.In this ontology there's a class "Developer" and a property "workTo" of this class. Using getDefinedProperties for the...
Look at your own output. The workTo property is not defined to have Developer as its domain. The only connection between Developer and the workTo property is...
Version 1.3.1 of Jena runs into a NullPointerException on the attached DAML fragment. However, version 1.3.0 is perfectly fine on that. - Thorsten <!--...
Sorry, I forgot to describe the call which causes the error in my last posting: DAMLModel model = new DAMLModelImpl(); model.read(in, "RDF/XML"); where "in" is...

Can you try to change all ID for about? I think you are defining classes without namespace ID="myClass" and you pretend to use it then without any namespace,...
