World.db - A Free Open World Database and Schema

Probably licensing. This one's public domain.

It is indeed extremely incomplete.

Based on the fact that this database is free and public domain, apparently it's possible for such data to have a restrictive license. So, I'm wonder what the sources of this data are? Is it compiled from public resources from the governments listed, determined and measured by hand by visiting the countries (with a GPS device in hand :P), or something else? I couldn't find this information on github.

Nice - much needed!

There is a UN office in Berlin devoted to Geographical names. They issue a 179 page manual about the standardisation of such names, but it is unclear whether they produce lists that could be used as the definitive source for a database of this kind.
