BANO is not designed to be used as an import source for OSM.
It uses sources (opendata, cadastre) that can be imported in OSM.
These sources have been used over the past years and will still be used to
add addresses in OSM, one at a time, or street by street which will take
years before completion.

So, BANO is there to allow to use all the available address data right now
without having to wait years to get them cleanly added to OSM.

This has one good side effect... reduce the pressure on massive address
imports in OSM and give us the opportunity to improve the quality thru
survey prior to add it to OSM.

Adding it to (the osm installation of) nominatim on the other hand is a

I'm pushing the french community to be more motivated on having all streets
and all streets name in OSM (BANO allowed us to detect 40% missing streets
or street names) more than adding addresses without surveying them.

I agree to motivate to collect BETTER address data... it we collect the
same data with the same quality level it looks to me more losing our time
than anything else.

In that case remove geonames and TIGER address search from
osm.orgNominatim instance.

I agree not to add these address data in the osm.org mapnik rendering to
avoid confusion.

I'm planning to add BANO dataset to improve OSM-FR tiles.

That's what I was thinking.

The is a BANO pull request on openaddresses.io to list it as an address
data source.
