Hi Bart

Just curious…why would you like to subclass the standard rdfs subclass 
relationship?
What is the added semantics in this case?

My advice is always to stick to the standard and not touch the 
meta-model/language whenever possible.

In general this causes incompatibilities between ontologies and within 
supporting tool sets.

Subject: [topbraid-users] subPropertyOf subClassOf

LS,

So if I use rdfs:label to name a class, TBC shows the label in the class 
hierarchy. If I choose to use skos:prefLabel instead of rdfs:Label, TBC 
correctly shows the prefLabel in the Class hierarchy. This is because 
skos:prefLabel is a subProperty of redfs:Label. TBC interprets this correctly.

Now if I make a subProperty of rdfs:subClassOf called qualificationOfConcept 
TBC correctly shows it as a subProperty of rdfs:subClassOf.

But if I use qualificationOfConcept to subType one Class to an other, it is not 
shown as a subClass in the Class hierarchy. So TBC does recognize that 
qualificationOfConcept is a subProperty of rdfs:subClassOf, but it does not 
treat it as such. It does not have the behavior of rdfs:subClass.[FormView.JPG]
TBC shows that the class GL:C2843 (Plural) is a subclass of Thing instead of 
GL:C790244 (Plurality)


What can I do to let TBC show the class correctly in the Class hierarchy using 
a subProperty of rdfs:subClassOf?

Kind regards,

Bart Bink.
