Dear Karl, I really like your proposal to tag only key-numbers at nodes and infer the rest (especially when ways are changed). Can anyone think of a way to optimize it for answering the question about the location of a single house-number without having to load all nodes of all ways that have a name similar to the one in the address? However I think overlapping ranges can only happen in the same case where random house-numbers in your scheme will occur...if people are editing the road and moving nodes around and sometimes entering garbage (typo, swapped numbers, having >1 node selected,...). A defined algorithm how to interpret the numbers and interpolate/extrapolate the missing numbers as well as examples for the usual cases would be a good thing. (linear-numbered sides, left-right -numbered sides, single house "2b" in a regular road, road only containing house 12 and 18 but no houses in between=how to disable interpolation.) Just to prevent having house-numbers and every piece of software interpreting them in a different way.
