This project uses [[ISO3166]] two-character country codes to name source and reference files. Available reference data files for countries that have or are being processed include:

*Belgium: [http://www.edegan.com/repository/GNS-BE.txt GNS-BE.txt]

*France: [http://www.edegan.com/repository/GNS-FR.txt GNS-FR.txt]

*Germany: [http://www.edegan.com/repository/GNS-DE.txt GNS-DE.txt]

*Great Britain (The United Kingdom of Great Britain and Northern Ireland): [http://www.edegan.com/repository/GNS-GB.txt GNS-GB.txt]

*Spain: [http://www.edegan.com/repository/GNS-ES.txt GNS-ES.txt]

*Switzerland: [http://www.edegan.com/repository/GNS-CH.txt GNS-CH.txt]

The perl module Match::GNS.pm loads, indexes and provides an interface to key variables from this data. The source code is the primary module documentation. The load() method takes and ISO3166 code, and the index methods and most other methods take one of two specific GNS FC codes (e.g. "P" for populated place, and "A" for administrative area).
