Hello Raphael, I missed that one, sorry. I think the reason is that David was asking whether we want to provide the functionality of a two way mapping, and not specifically referring to the expressive power of SKOS or another possible formalization which may be used to implement the functionality. If I understand you right you just explained the SKOS example, but did not ask for the functionality?
