ISO Language Codes (639-1 and 639-2)

Comprehensive language code information, consisting of ISO 639-1, ISO 639-2 and IETF language types.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.

本数据集为一套全面的语言代码信息集合，涵盖ISO 639-1、ISO 639-2及IETF语言类型。其收录所有带有ISO 639-2（Alpha-3/三位字母）代码的语言，附带对应ISO 639-1代码（若该语言存在此类代码），并提供每种语言的英语与法语名称。此类三位字母代码包含两种版本：书目型代码（bibliographic code）与术语型代码（terminologic code）。每种语言均拥有书目型代码，但仅有少量语言配备术语型代码；术语型代码的选取原则为与对应ISO 639-1两位字母代码保持形式相近。
