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?
