[Tagging] Tagging of historic=monument

[Matthijs Melissen]

Dear all,

Openstreetmap-carto (the default rendering style on openstreetmap.org)
will soon render objects tagged historic=monument with an icon.

There is currently a large number of objects incorrectly tagged as
historic=monument.

The definition of historic=monument according to the wiki:
'A memorial object, especially large (one can go inside, walk on or
through it) and made of stone, built to remember, show respect to a
person or group of people or to commemorate an event'.

Note that this tag should not be used for national heritage buildings
(called listed buildings in some countries). The word 'monument' does
not have this meaning in English. Instead, historic=yes, the heritage
key, or the listed_status key could be used for such buildings:
http://wiki.openstreetmap.org/wiki/Key:listed_status
http://wiki.openstreetmap.org/wiki/Proposed_features/heritage

It would be good to correct as many incorrectly tagged objects as
possible before the tag is rendered. This map can be helpful for that:
