Several addresses per building: addr:* tags on entrance nodes along the

Just a reminder that in many countries buildings can have several addresses, 
each address on different streets; none of the addresses is a primary 
address, and all staircases of said building are referenced just with a letter 
after any of the possible street addresses. The numbers can be on a separate 
lamp on each wall, away from any entrances. Which means that the house numbers 
really have to go as separate nodes inside the building, and each entrance only 
has the ref=letter on them.

Consumers need to support separate address nodes inside the building anyway, 
for that has been used extensively, so that should not break anything, either.

OK for multiple addresses and housenumbers for the same building, you
have this almost everywhere, but do you have cases where the same
appartment has multiple addresses?

As a general note I'd regard addresses on nodes preliminary, usually
it is a polygon that has an address. Whether or not the mapper can get
the information which is the polygon for a certain address is a
different issue (and here nodes are serving us sufficently well for
the moment).

cheers,
Martin

That's exactly what he's saying.

The addresses here are typically not for a part of the building but for
the whole building, or actually for land area it's in (lot? parcel? or
whatever would be proper English word for that land), so it could cover
even more than one building. And then a totally separate address space
for the apartments is combined to them to get the full address.
Apartment address space typically follows letter+number scheme. That gives
you 1ststreet numberX A 1 and 2ndstreet numberY A 1, etc. for the very
same apartment! ...This is not an exception but very very common here
(addresses are assigned for all streets a lot/parcel is touching so it
happens in practice at every road intersection). Officially none of them
is given priority but in many cases people tend to use one of them more
than the others. However, I've seen cases where the addresses given to
subscription systems were automatically reassign to another ones for the
delivery (more than once, I suspect it could be some delivery route
optimization feature).

In addition to that, we of course have buildings with different addresses
sharing a wall in packed areas which was probably what you meant with
you have this almost everywhere? However, again those adjacent buildings
could have here more than one address each.

After more consideration, and the helpful feedback from the list. I have

does anyone have any comments?

I don't think that catchment areas are suitable for OSM because they are 
not observable on the ground.


Also, the thought of having one area relation for each pizza delivery 
place in a medium-sized city makes my hair stand on end. Streets in that 
city would all become members of 10 or more relations, which would be 
broken 90% of the time.
