I see your point Martin. So all we need now (for your example) is a
documented map from shop=tobacco to a list of sells:*=* tags which are
default for shop=tobacco. One would reasonably expect
sells:cigarettes=yes, sells:pipe_tobacco=yes and
sells:rolling_tobacco=yes, but I am not sure about
sells:chewing_tobacco or actual devices such as rolling machines and
pipes. The product categories may also appear with other types of
shop, like shop=supermarket might have sells:pipe_cleaners=yes if
anyone finds it necessary to tag that. So we have a simple, flat list
of product categories, with a 1:n mapping from shop type to product
categories.
Tobacco shops
* Main tag: shop=tobacco
* Typical product categories and defaults for this type of shop:
** cigarettes (yes)
** pipe_tobacco (yes)
** rolling_tobacco (yes)
** chewing_tobacco (unknown)
** snuff (unknown)
** pipes (unknown)
** pipe cleaners (unknown)
** rolling machines (unknown)
Back to our chemists/drugstores/pharmacies, I would suggest
prescription_only_medicines, pharmacy_only_medicines,
general_medicines, plus a bunch of others to represent the wide
variety of things you get in "drugstores" like household_cleaning,
hair_products, etc.
The "art" is going to be choosing these product categories so they are
a) not so specific that the list gets too long and unwieldy and b) not
too high-level that they add too little distinction between the shop
types ("medicines" would probably be an example of this).
Once that is up and running .. people will then want to have the brand
of cigarette/snuff/tobacco .. as they only like one brand...
so
shop=tobacco
cigarettes=death;slow_burn
pipe_tobacco=old_smoky;blue_fart
