Hi Marc,

thanks for your help.

Do you mean at this page?

Silly question: What count of ppl is enough?

If it doesn't take you too much time, I would be glad if you can resume 
it? Would be good, so I can't damage something ;D
Do you add the changes to your wiki then?

*roof:ridge:direction* -> 1324 of 1330 have a roof shape specified (no 
nodes and no relations exist). If it is a single slope shape or not 
declared, can leave it like it is (or add an optionally note). 
Unfortunately I cannot read the corresponding values of shapes at 
TagInfo website.
For double-sloped roofs the more common tag is *roof:orientation* 
(across/along), but needs calculations and think it is too expensive, so 
the better approach is the 90deg rotated *roof:direction*.

Double-sloped would be: gabled, half-hipped, hipped, gambrel, mansard, 
round and saltbox (and eventually flat, dome, onion, and pyramidal shape)
Single-sloped: skillion shape (and eventually flat, dome, onion, and 
pyramidal shape)
