Ah, but there is a standardised list of country-codes ideal for the DBA since the code is (usually) easily understandable.
  http://en.wikipedia.org/wiki/ISO_3166
The only problem might be if historical data uses old boundaries (e.g. Soviet Union, Yugoslavia).

Yep, have all of them (ISO-2, ISO-3, UN), but they don't cover all countries + territories. Nevertheless, in most cases the list is sufficient...

Thanks nevertheless for the link!
