> I am in favour of using specific tags to group sets of things that belong
together, instead of using general tags like "amenity". But it's difficult
to teach an old dog new tricks. "Amenity" has been adopted so widely that
whenever a specific set of tags would be introduced, the question arises of
how to treat those things that have already been tagged as "amenity=*".
E.g. in the case of educational institutions, it would either be necessary
to maintain amenity=school or amenity=university, or double-tag these
institutions for the sake of backward compatibility as amenity=school and
education=school, or to automatic retagging of all amenity=school as
These difficulties, and opposing ideas on how to deal with existing tags,
make it hard to change established tagging schemes. But I am strongly in
favour of not establishing new amenity=* for hitherto unmapped facilites,
but rather use new tags altogether, whose use can then be expanded into
proper tagging schemes.
