Hi Colin, Thanks for getting this discussion started. I agree it's fine to use the proposal template also for proposals that are not about proposing a concrete tag.
One thing to take into account in this discussion is that multi-valued keys often move the problem to the data consumer. For that reason I'd recommend to avoid them in many cases. Take for example your example shop=supermarket, shop=bakery. Independent of the exact way of tagging, using a multivalued tagging scheme forces the renderer to make a decision between a supermarket and a bakery icon. Basically, there is no possible way for the renderer to support a multi-valued key here! The renderer might have a rule that considers supermarkers always more important than bakeries, or vice versa. But I think it's much more useful if the mapper decides what's the main function, supermarket or bakery, rather than forcing the renderer to make a choice. -- Matthijs On 27 January 2016 at 16:09, Colin Smale <colin.sm...@xs4all.nl> wrote: > Dear all, > > I have created a proposal page as a channel for constructive debate about > the way forward.
