Compared to conflating names or geometries, addresses are not a problem because the street and the housenumber form a unique id. Before comparing them it is worth splitting the street name into words, reordering the words within the name to order them lexically, and abbreviating them using a not-necessarily-perfect word list (such as that from tiger or nominatim), to account for variations. We've had to do that for one city recently but it turned out to be a simple check. The (150 loc) conversion script for that data would read 4 files: * the new addresses in a particular format, * an output of an overpass/xapi query for elements tagged with adds:housenumber=* * an output of an overpass/xapi query for ways tagged with building=* * an output of an overpass/xapi query for named highways. it would output: * an .osm file adding the addresses missing from OSM, either attached to existing buildings or added as nodes * a list of potentially missing streets who's names appeared in the addresses.
