As I just added to the twiki discussion page, I agree with Markus and Francois 
that we should allow NULL for dataproduct_type rather than introduce "other". 
I am very strongly against hack special values like "other", "none", 
"unknown", etc. when SQL has the correct concept and it behaves correctly when 
queries execute.
