I think there's a discussion to be had there. 

URI templates haven't seen wide deployment yet because the draft has been dormant for so long (sorry), but Roy's put a fair amount of work into it recently, and is making noises about shipping it soon. I'm also hearing about multiple implementations (even in C) based on the recent work. 

I'm wary of assigning resources the magical name "collection" with the implication that you can assume very specific behaviours regarding query parameter parsing, etc.; it's very tightly coupled. 

Cheers,
