Hi Luc,

Here and in other threads I'm not sure what you mean by non-aligned.  As discussed concerning ISSUE-253, there are lots of other things that can be said using the RDF vocabulary that don't necessarily correspond to things that can be said in DM syntax.  But so what?  How does this harm interoperability?  What property do you expect that isn't established here (e.g. some kind of roundtripping property).

I think it is interesting to make this explicit so that we can try to achieve it (or agree whether it's achievable/desirable).
