[Tagging] I started a draft on a new "main" key culture

[M∡rtin Koppenhoefer]

I would like to invite you to take part in the discussion for a new
key "culture".
The first draft is here:

http://wiki.openstreetmap.org/wiki/Proposed_features/culture

the discussion should mainly take place on the mailing list IMHO,
because I consider it more suitable for discussions.

cheers,
Martin
