In the W3C LBD we are comparing different ways of modelling (complex) properties.
One option: ex:Height rdf:type bs:PropertyType ; bs:hasQuantity cdt:length . ex:Door_1 rdf:type ex :Door ; bs:hasProperty ex:Height_1 . ex:Height_1 rdf:type bs:Property ; bs:hasPropertyType ex:Height ; bs:hasValueUnit "2.40 m"^^cdt:length . but some people think the XType modelling is too much. So they like to just specialise bs:Property into ex:Height resulting in: ex:Height rdfs:subClassOf bs:Property ; rdfs:subClassOf [ rdf:type owl:Restriction ; owl:hasValue "cdt:length" ; owl:onProperty bs:hasQuantity ; ] . ex:Door_1 rdf:type ex :Door ; bs:hasProperty ex:Height_1 . ex:Height_1 rdf:type ex:Height ; bs:hasValueUnit "2.40 m"^^cdt:length . so the original: bs:hasQuantity cdt:length . becomes a restriction in the second option. BUT...as can be seen instead of just cdt:length I have to specify "cdt:length" with quotes (just cdt:length does not work in tbc) (the range of hasQuantity is rdfs:Datatype) In the constraint. Is this actually doing what I intended? Thx Michel Ps related to my earlier OWL Full question, guess an OWL Full option could also be: ex:Height rdfs:subClassOf bs:Property ; owl:hasQuantity cdt:length . Dr. ir. H.M.
