Hi Dominic, Lorenzo I note that the UML that appears in this is inaccurate as to CF around cell methods and measures as well, and perhaps getting that right might help. (One could model cell methods as an association class between a variable and a coordinate, or a specialisation of a variable, but it's certainly not a string ... likewise cell_measures are an enumeration attribute of the cell method). With those pieces in play wouldn't this proposal be much simpler? (I have to say that cell_methods are strictly associated with coordinates, rather than other variables, but I'd rather see the same fundamental mechanisms re-used, rather than new ones introduced).
