it is "addr:city". There is no "left" or "right" as we use separate ways just for this. (There are reasond for it.) The perfect way are single houses drawn as polygons with building=yes and addr:housenumber=xy , the next best thing nodes places where each house is and the next best thing is 2 or more nodes where single house-numbers are known connected by a way tagged addr:interpolaton=even/odd/... to we can calculate where each house would be. You can use Traveling Salesman to test actual, working house-number search. >> For the geobase2osm script we excluded this feature, as we couldnt >> figure the best way to tag. >> Now I found that the data is also available in the canvec set. >> So one option is to have it as a way over top of the roadway. > > We're importing a small number of streets from a project called UMP > pcPL that has similar housenumber data as you describe (for *some* > streets).

One suggestion: As this is automated anyway, try to add hints about what street the houses belong to. easy to implement version: Simply add a tag add:street=nam to the interpolation-ways slightly less easy to implement but easier to evaluate in address-search: add an associateStreet- relation I will download that area one of these days and play around with my address-seach a bit, okay? With so much test-data I may be able to improve the algorithm I use to associate the street with the house-numbers :) .
