I am uncomfortable in addressing this kind of discussion - it's not clear to me.  in the draft we are we providing a taxonomy of dimention or are we leaving this open

13:54:57 <JoaoPauloAlmeida> you don't really need to go datacube style (with SPARQL queries) you can just declare the properties functional... and the cardinality is not an integrity constraint!
