"""
We have defined a 
sub:isMainConceptOf  a owl:ObjectProperty ; 
            rdfs:range skos:ConceptScheme ;
            rdfs:domain skos:Concept ;
            owl:inverseOf skos:hasTopConcept . 
so it was great to see that skos:topConceptOf is in! Please keep it there, it 
is simply much easier for us to use it in development with the present 
architecture.

I haven't followed the debate since this first was debated, but I would like 
to bring this up again: I do not like the naming of skos:hasTopConcept and 
skos:topConceptOf. As long as there are associative relationships in the 
system, it seems meaningless to make the hierarchical relationships more 
prominent than the associative by connecting this property to the hierarchy. 

So, that's why I called my inverse of skos:hasTopConcept isMainConceptOf. I 
think something like that would be better. 

I haven't thought too carefully about it, but what if:

<S> rdf:type skos:ConceptScheme ;
  skos:hasTopConcept <B> .

<B> rdf:type skos:Concept .

<A> rdf:type skos:Concept ;
        skos:related <B> .

would this be consistent?

I think that's fairly inevitable in our system, and it would certainly break 
things if we couldn't do this. What if <B> skos:broader <C> . ?

Requires discussion.
