Hello and thanks for checking before the import!
License is important, sadly it seems to not be specified anywhere.

I just looked at it and it seems that either it is not specified or I missed it.

If nobody will be able to locate that info then emailing specified contact would be a good next step.

So unlike work of federal government it is not automatically public domain.

On the other hand, it may be unoriginal database... Still, the preferred version is to have an explicit
license.

> I don't have anything like an extensive plan for carrying out an import, which is why I did not include the "authoritative" imports mailing list yet. However, at a high level, as I am a software engineer by trade, my plan is to write a script that reads the shapefiles and an .osm file dump as input, does the attribute to tag transformations, and deduplicates with the existing data by excluding any address points that already exist in any OSM object with equivalent addr:* tags (it might also be necessary to inspect all associatedStreet and street relations). It would produce an .osm as output that contains nodes with just addr:* tags. This can then be opened in JOSM and merged into the standard data layer. I'd probably start with a single county and go from there.

Similar things were done already so remember to check whatever existing tools for
converting and conflation are good enough to use/modify rather than start from scratch.

Like OSM mapping in general.
