#62 RDFXMLOntologyFormat should use entities in rdf:about

[Allen]

Seems like PrefixOWLOntologyFormat does not work for RDFXMLOntologyFormat. The saved owl file will not use prefixes even if it prefixes were specified.

Hi, can you clarify the expected behavior?

By printing out the prefixes as in the code sample, I get:

Test.main() http://www.w3.org/2001/XMLSchema#
Test.main() http://www.w3.org/2002/07/owl#
Test.main() http://www.co-ode.org/ontologies/pizza/pizza.owl#
Test.main() http://www.w3.org/2006/12/owl11-xml#
Test.main() http://www.co-ode.org/ontologies/pizza/pizza.owl#
Test.main() http://www.w3.org/1999/02/22-rdf-syntax-ns#
Test.main() http://www.w3.org/2000/01/rdf-schema#
Test.main() http://www.w3.org/2006/12/owl11#
Test.main() rdfxml: http://www.w3.org/2001/XMLSchema#
Test.main() rdfxml: http://www.w3.org/2002/07/owl#
Test.main() rdfxml: http://www.w3.org/2006/12/owl11-xml#
Test.main() rdfxml: http://www.co-ode.org/ontologies/pizza/pizza.owl#
Test.main() rdfxml: http://www.w3.org/1999/02/22-rdf-syntax-ns#
Test.main() rdfxml: http://www.co-ode.org/ontologies/pizza/pizza.owl#
Test.main() rdfxml: http://www.w3.org/2000/01/rdf-schema#
Test.main() rdfxml: http://www.w3.org/2006/12/owl11#
<?xml version="1.0"?>
<rdf:RDF xmlns="http://www.co-ode.org/ontologies/pizza/pizza.owl#"
xml:base="http://www.co-ode.org/ontologies/pizza/pizza.owl"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xmlns:pizza="http://www.co-ode.org/ontologies/pizza/pizza.owl#"
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#">

So the prefixes look like they are there, hence I suspect I might missing the point.

Sorry I did not make point clear. What I meant was I need to generate output file using "RDF/XML-ABBREV" format (the short format).

What I expect for the output:
<owl:ObjectProperty rdf:about="#hasBase">
<rdf:type rdf:resource="&owl;InverseFunctionalProperty"/>
<rdf:type rdf:resource="&owl;FunctionalProperty"/>
<rdfs:subPropertyOf rdf:resource="#hasIngredient"/>
<rdfs:range rdf:resource="#PizzaBase"/>
<rdfs:domain rdf:resource="#Pizza"/>
<owl:inverseOf rdf:resource="#isBaseOf"/>
</owl:ObjectProperty>

What I got for now:
<owl:ObjectProperty rdf:about="http://www.co-ode.org/ontologies/pizza/pizza.owl#hasBase">
<rdf:type rdf:resource="http://www.w3.org/2002/07/owl#FunctionalProperty"/>
<rdf:type rdf:resource="http://www.w3.org/2002/07/owl#InverseFunctionalProperty"/>
<rdfs:domain rdf:resource="http://www.co-ode.org/ontologies/pizza/pizza.owl#Pizza"/>
<rdfs:range rdf:resource="http://www.co-ode.org/ontologies/pizza/pizza.owl#PizzaBase"/>
<rdfs:subPropertyOf rdf:resource="http://www.co-ode.org/ontologies/pizza/pizza.owl#hasIngredient"/>
<owl:inverseOf rdf:resource="http://www.co-ode.org/ontologies/pizza/pizza.owl#isBaseOf"/>
</owl:ObjectProperty>

I may misunderstood the API and need to use some other functions to get "RDF/XML-ABBREV" format?

Ah I see, it's not just the namespace prefixes but the entities. I'll look into it.

[Ignazio Palmisano]

I cannot see an easy fix for this, but it is not a functional issue. Moving to feature requests.
