What are the accepted Tags for Sanatoriums?

And movie shooting studios? (not movie companies by studios where shootings take place)

Sanatoriums / sanatoria - I’d say it should be amenity=clinic (or hospital if it is a large one).

Studios of any non-retail kind - building=commercial or building=industrial

But we probably cannot classify all types of buildings; just put a reasonably appropriate key/value pair on it, plus a name.

e.g. Sanatorium
