Usually the postal address which you give in your official documents is considered the primary. But this address may not be suitable for other uses. E.g. I live in an apartment complex that extends over 2 building blocks: http://www.openstreetmap.org/relation/1060497 The postal address is Davidgasse 76-80, staircase (addr:unit) 14. My windows are heading to the Buchengasse. The Davidgasse is not even adjacent to the whole block. So nobody finds to me when I tell them my postal address. I need to tell them I live in Gußriegelstraße 5, because that's the location of the building passage that leads to the correct corner of the courtyard. The chimney sweep uses Buchengasse 151 though, because that's the street where my apartment (and the chimney) is located. So I'd say that Davidgasse 76-80 is the primary address (addr:*), Gußriegelstraße 5 the secondary address (addr2:*), and Buchengasse 151 the tertiary address (addr3:*). Malborghetgasse 6 (addr4:*) and Rotenhofgasse 86-88 (addr5:*) are also equivalent, but are never actually used for my side of the building. > And > if that's the case, what's wrong with creating a node on the building for > each additional valid address?

It's not a clean situation, It's a "best guess" approach, delivering lots of false positives, because the scope of address nodes is undefined. The address may be valid for the whole building, or only part of the building, or even for multiple buildings (take my postal address as an example). > but it does have a couple advantages: > > * Works with existing data consumers That's fine, but if that were a criterion, OSM wouldn't exist.

And you don't need to create additional nodes, let alone relations as suggested somewhere in this discussion. -- Friedrich K.
