[Tagging] tagging awards and ratings

[Johan Jönsson]

Sometimes there is a discussion on how to tag differnt kind of awards and 
ratings.

I thoguht a bit of this http://wiki.openstreetmap.org/wiki/User:Johan_J%C3%
B6nsson/Workspace#some_musings_on_the_subject

and came up with a pre-draft that I might take further if there is any 
interest:

B6nsson/Workspace#A_preliminary_proposal

It is basically like this
<Award_System>=<Award>

With a catchy name for the award_system as key
and for each award_system there could be a list of values

example 1
Tripadvisor have some awards called Travelers' Choice
If someone of some reason would like to tag that, they can use
travelers_choice=top25 / best_service

example 2
Guide rogue Michelin awards restaurants
Michelin=2_stars

example 3
there are many hotel star-systems, one is HOTREC by hotelstarsunion
(see http://wiki.openstreetmap.org/wiki/Key:stars)
HOTREC=3_stars

example 4
In the blue flag system beaches are rewarded with the blue flag award
blue_flag=blue_flag

As you see from the examples, there are some things to discuss.
