I like this approach.
Ian and others in the thread have described address imports as a sort of
"computer-assisted manual editing", and I think for US addressing it's a great
approach. The gulf between urban and rural parts of the U.S. is wide, and if we
don't take advantage of the excellent local government data available for these
purposes there are going to be regions of the country that *never* get mapped.
I believe that we should develop an approach that is welcoming to local
government representative who can help with the assisted importing, which may
involve doing a few test imports in known places followed by the development of
new tools or description of new procedures that newcomers to OSM who already
steward local address databases can repeat for their own jurisdictions.
First step would probably be a plan for shitty TIGER data - what should these
local government folks do in cases where their local OSM coverage is pure TIGER
2007 drek? Just to name a local example, Mill Valley CA is right across the bay
from SF and composed of mostly import junk. Maybe "someone" (heh) could do a
purpose-built fork of Potlatch designed especially for pulling in address info
without displaying any other road data to eliminate confusion, for use by
owners of address info who know they have good, high-precision coverage.
