Didn't mean to sound like you did.  I actually did in the past by not 
paying enough attention to the plugins,  I'm in the process of fixing 
this btw :)

Sorry, I had to check before talking.  The building key is open for free 
tagging I think anyway, so it would not be an error anyway if it's not 
on there (yet).

nice suggestion, I'm going to start doing this too.

you probably know this , I noticed only the deepest zoom level has all 
the numbers they know about. But I second that it's not the address 
bible I first thought it would be.

I pretty much do the same using nodes.  But then I use the terracer 
plugin,  it's not only awesome to split houses in 1-2-n pieces but you 
just select a street + an addr node and a building and press SHIFT-T.  
It will put the street name in the the building tags.

Next I use fixaddresses to complete the other tags, some logic is used 
to auto-guess the streets, which sometimes fails miserably but all the 
rest is filled out for you and most of it is correct, it just needs a 
human to apply the guesses/changes.

Not convinced yet I see :)

I would omit the housenumber, that's what I do.   tagging it as 'z/n' is 
the same as putting an imaginary number on it, e.g. it's an error.  What 
I find difficult is buildings with an address containing a business 
(shop/amenity) with a separate address from the building (or the same 
sometimes, but the building itself has several numbers).   There I see 
the merit of not duplicating data...  I eventually settled for tagging 
the adress information on the building (less likely do disapear) and 
putting the amenity within the building border (and try to remove 
existing duplicate address data on that node).

Businesses are far more likely to be gone in 10 years than buildings, 
when you put the address data on the node instead of the building, 
chances are great that the address info will be deleted too in the 
process.  But putting the same address info  on both (I tried some 
localy - it's ugly and I need it fixed soon) is very ugly on the map 
(duplicate housenumbers visible).    It makes sense for me, when the 
shop is gone, you can remove the node entirely, and all address info 
related to the building is still there.
