Simple ISO 639-3 is a small library to convert languages codes between ISO 639-1 (two letters language codes) and ISO 639-2 (three letters). It is built from the official standard lists ISO 639-3 of (SIL) and is compatible with IETF language tags (RFC 4646).

Note: The current standard (2007) uses the native language as a base for the codes. For example, three letters code for French is fra, not fre, or, for Chinese, zho, not chi. English language is deprecated.

This library is used in the module Internationalisation for Omeka S.
