[OSM-talk] tutorial for mapping buildings?

[John Whelan]

What I'm interested in is something a new mapper (probably HOT) can 
refer to when they are mapping.  So it needs to be fairly comprehensive 
to stop the young ladies and gentlemen from being a little too creative 
in their tagging.

HOT asks them to map buildings but may not explain in the project 
instructions how a "non-standard" building should be mapped and I'm 
seeing some very creative efforts as I search for duplicate buildings.
