Using Language Identifiers (RFC 3066)

Language identifiers as specified by RFC 3066, can have the form language, language-country, language-country-variant and some other specialized forms. The guidelines for choosing between language and language-country are ambiguous.

To clarify which form should be used, John Cowan and I have posted this list for review. This is currently a draft document. It will be continually revised as we get feedback from linguists and internationalization experts. (Although, I have a day job, so allow some time for me turn it around.) The topic is being discussed on the W3C www-international mail list and the IETF ietf-lang mail list.

Send comments to Tex Texin and John Cowan. To improve turn-around of edits, please make sure the mail uses the subject: "Language Identifier List Comments". This will help us easily identify the mails and process them. Please use a different subject for other discussions.

There are a number of suggestions for deciding whether to use a one-level (language only) or two-level (language-region) tag. They require some discussion and will be added here shortly.

Language codes are from ISO 639. Country codes are from ISO 3166.
