Obviously, since as John pointed out all different data representations are
essentially logical equivalent. I think this a case of confusing logic with
semantics. The question should be: are all these so called "conceptual views"
represent the same concepts. (02)

The void can only be bridged with reach semantics providing intended
interpretation and composition for conceptual structures. RDF does not provide
these (IHMO). Looking at the pretty pictures in your link I don't see how all
different databases at the bottom end-up exposing conceptual view at the top.
Can you explain? (04)
