I'll be interested to read it. This topic is quite interesting (even if 
you go for the case with the generation of the 2 different links based 
on the type of the resource filled by the user) , if you have time in 
the coming weeks we should try to formalize it as a SKOS use case. I 
thnk the first link (semntic equivalence between concepts) is a nice 
concept scheme mapping case, while the second will provide more flesh 
for a possible requirement on representing reference of skos:Concept.

Good luck, and sorry for giving only limited help.

Cheers,
