Generally, I wonder how to connect the product proxies to the taxonomy 
proxies. I have to admit that I had the TMDM definition of isa [1] and 
sub [2] in mind (but cited TMRM).

Imagine the T-Shirt Nike "Summer" classified as "Lifestyle Product" 
(another product classified here might be some adidas sunglasses). 
Lifestyle Product "captures some commonality" [1] ("some commonality": a 
set of properties that hold for both, the t-shirt and the sunglasses?And 
what, in contrast, constitutes a superclass?). Would you still say

- T-Shirt Nike "Summer" sub Lifestyle Product

? Not sure (need rules not feelings :-) ).

Well, I wonder what's the difference of capturing some commonality [1] 
and a "more general type" [2] - or is it just transitivity and reflexivity?

Best regards,
Johannes
