Hi, Thanks all for your thoughts. Will and Holger seem to have the same approach as me, which gives me the confidence to edit the wiki and at least document this approach: http://wiki.openstreetmap.org/wiki/Addresses#Buildings_with_multiple_house_numbers
Hopefully I've done it in a way which won't anger those who dislike the idea: ;) Dan 2014-08-19 22:45 GMT+01:00 Will Phillips <wp4...@gmail.com>: > I often use the addr:interpolation tag on entrances or buildings. I don't > understand some people's objection to this. I don't see any ambiguity: if > the addr:interpolation tag is present the addr:housenumber tag represents a > range, otherwise it should be interpreted as a single address. As someone > who maps addresses regularly I find this a quick and convenient way to do > it.
