IETF Language Tags for LANGDEV Languages

Introduction

The organization of documents within the LANGDEV Project is based heavily on the IETF language tags. The LANGDEV Project defines a number of IETF-compliant subtags for use with LANGDEV languages.

The LANGDEV subtags have been chosen so as not to conflict with existing registrations; however, as they have not been registered, they should be preceded by the private-use x subtag in practice. For maximum clarity, it is recommended that IETF tags for LANGDEV languages consist of the following components, in order:

  1. The primary language subtag art, which denotes an artificial language
  2. If the language is being written in a registered (non-LANGDEV) script, the corresponding script subtag
  3. The private-use subtag x
  4. The (unregistered, non-depreciated) primary subtag for the language, as defined below
  5. If the language is being written in an unregistered (LANGDEV) script, the corresponding script subtag
  6. If the language tag should denote a particular defined variant, the corresponding variant subtag(s)

For example, the correct language subtag for Jastugay written using the Latin script would be art-Latn-x-jst, and the correct language subtag for Classical Sevensi written using Ancient Sevensi Runes would be art-x-svi-Sevr.

Processors which wish to support LANGDEV languages should interpret any tag which matches this sequence as a LANGDEV language tag.

The tags

Language collections
Parent Tag Name
flu Fluîne
fzn Fizonal

Language-collection subtags should only be used if a more specific primary language subtag is not applicable.

Note that parent language-collection subtags are not necessarily LANGDEV-specified (ie, they might be registered IETF tags).
