I don't think it's off topic at all.

I have generated a file "lots.osm" which has parcel data as polygons
with boundary=parcel tags, and just call splitter with
"us-northeast-latest.osm.pbf" and "lots.osm".

My lots.osm file has negative numbers for ids.  I remember using some
python code to read shapefiles and write the osm file, but I no longer
remember the details.  There is nothing odd about the file, other than
using negative ids.

With 64-bit ids, perhaps I should be picking some other private range
that isn't negative.  But I bet it doesn't matter as long as they are

I've been doing this for years with no problems.
