Hi, nevermind my previous comment asking about documentation for the Rust source. I figured out I can get the data by a query to the 'Overpass' API, using https://overpass-turbo.eu/. The query is very simple:

node [place=village] (around:20000,lat,lon); out;

Then I can download that as GeoJSON and sort it with a little Python script or whatever, which is basically all I need.

Thanks again for kicking this off!
