I then import the geobase roads and tag each way with the uuid (geobae:uuid) that mostly identifies the source road segment. I exclude the roads flaged as already being in OSM. Once I have the road network dealt with I (or another eager volunteer) can create the address nodes+interpolation ways using some of the methods discussed on the thread. Connecting the interpolation ways to the previously imported nodes with a realtion shouldn't be hard. I know the uuid that the address applies to. I can get the way_id by searching a local copy of the OSM database for that geobase:uuid. A script can then get/edit/upload the existing way though the API. The script we are using for importing the base roadnetwork is available http://svn.openstreetmap.org/applications/utils/import/geobase2osm/ I am currently working on another script to fix some issues in the some of the roads imported so far (a bug prevented some intersections from sharing a node). This will use the local lookup, query ,edit technique I discussed above.
