Re: [dotNetRDF-Support] Protege Ontology IRI for DotNetRdf Created ontology

[altaf h. <alt...@ya...>]

Thanks Rob for your prompt response. 

I have checked based on your suggestion, but as I checked on API documentation, there is no way of adding Owl:Ontology object. The "Ontology" meta-info class has no way of doing so. 

In addition I have checked to add via underlying ontologyGraph, but only there is ways to add property/resource/class will actually be serialized as owl:Class or Owl:Properties. 

I have investigated on Protege created ontology, here is how it doing in two cases: 

1)
<rdf:RDF xmlns="http://www.pz.com/mypizzafactory.owl#"
     xml:base="http://www.pz.com/mypizzafactory.owl"
     xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
     xmlns:owl="http://www.w3.org/2002/07/owl#"
     xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
     xmlns:mypizzafactory="http://www.pz.com/mypizzafactory.owl#"
     xmlns:ace_lexicon="http://attempto.ifi.uzh.ch/ace_lexicon#">
 
    <owl:Ontology rdf:about="http://www.pz.com/mypizzafactory.owl"/>

2) <Ontology xmlns="http://www.w3.org/2002/07/owl#"
     xml:base="http://altaf.ongology.org/HardwareOntology"
     xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
     xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
     xmlns:xml="http://www.w3.org/XML/1998/namespace"
     ontologyIRI="http://altaf.ongology.org/HardwareOntology">
....

Clearly, OWLApi handled these specially. I have no idea for a work around. May be from these two case, you might find something (Just hoping).


Thank you so much for your support.


 

Kind Regards,

The Base URI is simply the URI used for resolving relative URIs it is not the ontology URI and is not necessarily serialized depending on the RDF syntax used.

From what I understand of OWL the Ontology IRI is the one declared in the actual triples typically by adding a foo rdf:type owl:Ontology triple to your ontology where foo is your desired ontology IRI

But I don't know OWL very well and have never used Protégé so no guarantees that this will resolve your problem
