[Tagging] Feature Proposal - RFC - temperature

Hi all,

I wonder: shouldn't we separate a conditioned room air in a hotel and
an object temperature? I get the feeling that this discussion on a
useful tag (how to denote the temperature of an object where it is
needed) is slowly drifting away to defining about everything related
to temperature.

I would concentrate on a set of specific examples (where are
mappers/data users likely to want to tag/know the temperature?) and
just define the set of the tag values for them. The cases that are not
explicitly temperature-related shouldn't be covered by this tag in my

An air-conditioned hotel room is a good counter-example for this tag.
It's the comfort level rather than the temperature that is the goal. A
temperature of the room is the secondary parameter here. Everyone
would understand what an air-conditioned hotel is, but I would
struggle to know whether +25 °C in July is comfortable for South Korea
or not if I see it in the map.

On the other hand, there may be a good exception. The American
consulate in Moscow is notoriously known for overusing air
conditioning and causing severe colds. People are advised to take
pullovers and scarves with them in summer. I've experienced the same
in McDonald's in Hungary. +20 °C may be a comfortable temperature but
not when it's +35 °C outside and the conditioner is blowing like hell
onto your head to keep the temperature down. For such cases, one could
tag the place as AC-ed and cold.

Summary: I suggest to use this tag (and discuss the recommended values
for it) only for the temperature specific cases, not for the whole set
of objects having some temperature.
