Hi Ben,

I did not see any handling of abbreviations in your python code. If
the source data has abbreviations, they should get expanded by the
conversion scripts. Regardless, you should talk about abbreviations in
the import plan, since they are often issues when doing address
imports.

Some recommendations.

- Consider doing some conflation ahead of time in the script. It would
be possible to eliminate any address that already exist inside of OSM.
- You could also make a "conflict" output file, that has identical
addresses between OSM and the source data and but with positions that
are above some threshold. Another possible conflict you could spot
ahead of time, would be seeing if a street name in the address,
actually had a street with the same name nearby. These will be much
more work than the non overlapping addresses, having them separate
insures that they get looked at carefully.
- Since you are using JOSM, you might want to consider developing some
JOSM filters to help with the import merging.

Good luck!

Thanks
Jason
