The
Internet Request for Comment document about
Tags for the Identification of Languages (
ftp://ftp.rfc-editor.org/in-notes/rfc3066.txt). It provides a way to register extensions of codes for language names in
ISO 639. The current reviewer of new tags and maintainer of the registry is
Michael Everson (
http://www.evertype.com/standards/iso639/iana-lang-assignments.html). An alternative for language codes is the
Ethnologue.
