RE: Question about value vocabularies and range

I didn’t check this, but I think it would work:

 

tbox:myProperty a owl:ObjectProperty;

                rdfs:range [

rdfs:subClassOf skos:Concept;

rdfs:subClassOf [

                owl:Restriction [

                                owl:onProperty skos:inScheme;

                                owl:hasValue <http://example.org/some-skos-concept-scheme>;

                ];

];

];

                .

Surely the application profile approach is better for two reasons:

 

1. You can use the vocabulary encoding scheme entity to specify the vocabulary for the range of the property.

2. Different profiles can specify different VESs, so use of the property is more flexible than if OWL constraints were declared.

 

[But it's a mystery to me how the AP approach can be 'translated' into OWL, so I'll echo your request: can anyone explain if it is possible to use OWL to restrict range values to what is effectively an instance of skos:ConceptScheme (which is a class, ok, but it's a specific instance of a concept scheme that contains the values for the range constraint).]

 

Cheers
