Hi I am working on the new jena2p4 inference model and ontology api. I can see that infernece in DAML is based on transative and RDFS (if i am correct). and...
It looks like setNsPrefix() methods were moved to PrefixMapping and disappeared from interface RDFWriter. Unfortunately, because of this, they are no longer...
Hello In RDFS the properties are inherited from superclasses? If yes, I think this is a valid rule for RDFS: [propertiesFromSuperClass: (?x rdfs:domain ?y),...
Hi, We are not doing any specific work to support DAML inference. After all we haven't even managed to complete the OWL/Lite work to our own satisfaction :-) ...
... Correct. ... I'm afraid not in RDFS itself, but it is valid in some languages built on RDFS. The definition of rdfs:domain (and similarly rdfs:range) in...
Hi Could you tell me a some information about the rule files in etc. are they written in say flora syntax or what type of a logic syntax. can i add rules of my...

Andrzej, thanks for your question. The short answer is perhaps in autumn. The long answer is that it is not easy and that we will discuss these issues soon...
Storing fully-qualified names in Protege would indeed be awful. Fortunately, its completely unnecessary. Our (hacked) version of Protege uses qnames ( e.g.,...
Hi Dave, Thanks for your reply. ... OK! Got it finally! What did not click for me, was that hasRDFType() may return incorrect results if invalid() is true. I...
... While I doubt this is the contract Dave will/has implement, a logically correct contract when given an inconsistent input would return that all possible...
Ah, sorry I misread your proposed rule as being about superclasses. In that case, I don't think your proposed rule is valid, whichever of the if/iff semantics...

Do you have a particular need to use the legacy DAML API? Because, as I have said already, the main ontology API will handle DAML as well as OWL and RDFS, and...
... You could try using the correct daml namespace - the model writer should then recognise it. Alternatively model.setNsPrefix( "daml", namespce ); should do...
Hi thanks for your reply. I wonder if you mean by legacy DAML that i am using DAML instead of OWL. or i am using API that is not in the ontology?. i changed...

Jena-developers, I use Jena2p4. I have an RDFSModel that I want to query. But when I try an RDQL query that has more than 10 patterns in the 'FROM' clause I...
Stanislav, There should be no limits on the RDQL query. We will look at this. Could you post the queries themselves? Andy ... From: Stanislav Pokraev...
Hi all, Almost certainly this is a well known problem; I understand optimization is underway. Just offering this data point: Loading the W3C Wine ontology,...
The ontology API is com.hp.hpl.jena.ontology. This will handle DAML+OIL, OWL and RDFS. The legacy DAML API is com.hp.hpl.ontology.daml. This is not stable;...
