Description
Comprehensive language code information, consisting of ISO 639-1, ISO 639-2 and IETF language types.
Data
Data is taken from the Library of Congress as the ISO 639-2 Registration Authority, and from the Unicode Common Locale Data Repository.
data/language-codes.csv
This file contains the 184 languages with ISO 639-1 (alpha 2 / two letter) codes and their English names.
data/language-codes-3b2.csv
This file contains the 184 languages with both ISO 639-2 (alpha 3 / three letter) bibliographic codes and ISO 639-1 codes, and their English names.
data/language-codes-full.csv
This file is more exhaustive.
It contains all languages with ISO 639-2 (alpha 3 / three letter) codes, the respective ISO 639-1 codes (if present), as well as the English and French name of each language.
There are two versions of the three letter codes: bibliographic and terminologic. Each language has a bibliographic code but only a few languages have terminologic codes. Terminologic codes are chosen to be similar to the corresponding ISO 639-1 two letter codes.
Example from Wikipedia:
[…] the German language (Part 1:
de) has two codes in Part 2:ger(T code) anddeu(B code), whereas there is only one code in Part 2,eng, for the English language.
There are four special codes: mul, und, mis, zxx; and a reserved range qaa-qtz.
data/ietf-language-tags.csv
This file lists all IETF language tags of the official resource indicated by http://www.iana.org/assignments/language-tag-extensions-registry
that into the /main folder of http://www.unicode.org/Public/cldr/latest/core.zip (project cldr.unicode.org).
