Hi Mike,

I do indeed mean a 'universal product identifier' (my chosen terminology 
came straight from the hreview wiki page).  At the most basic level, we 
need to know whether two products are the same.  To that end, we 
currently 'understand' the custom urn's at this location[1].  The part 
that is currently incomplete is the resolution of all urn's for a given 
product to that one product (a process that's improving over time).

As Tantek mentioned, this concept is basically unrelated to a product 
microformat itself.  However, I'm interested in what use cases people 
have for a product microformat that don't involve knowledge of whether 
two products are the same / product identification?
