Language code maintenance activities of the LCA include:
To propose a Change Request for ISO639-3, submit a statement document to the Registrar of the Language Coding Agency for ISO639-3 outlining the purpose of the change, elaborating how the proposal meets the criteria listed for the type of change, and listing sources of documentation in support of the change. When preparing the proposal, notify the Registrar using thisGoogle form, which will initiate tracking of the request. The Registrar will contact the email address supplied in the form to offer assistance in the process such as additional tips or information to include, feedback on a draft proposal, or progress updates. Note: for requests that include a Create (Create or Split) make a separate document supplying as much of the relevant information as possible, including citations, listedhere.
Types of Changes defined in the 639:2023 ISO standard
Modify reference information for an existing code element Note: the 3-letter identifier of the language code element shall never be modified!
Modify a Language Reference Name (for exceptionally compelling reasons)
Modify Additional Name (add, change or delete names in English or French)
Change non-normative information such as language Type
Deprecate (Retire) - an existing language code element from use, including possible merging of its scope of denotation into that of another code element, for one of the following reasons:
Non-existent - no evidence of language
Duplicate - code denotation same as [zxx]
Create a new Language Code Element - requested language must meet the full language and individual language criteria
Full Language requirement for language coding
Used in a broad range of domains
Supports communication across all social segments of the language community including all genders and age groups
Stable enough to have at least one variety that is widely understood across its whole geographic area over the time span of more than one generation
The language is changing gradually as each new generation of speakers makes it their own
Eligibility for coding as an individual language - the distinction between a language and a language variety/dialect follows these guidelines:
Two related language varieties are considered to belong to the same individual language if speakers of each variety have inherent understanding of the other variety at a functional level (i.e. they can understand each other based on knowledge of their own language variety without needing to learn the other language variety). Where such mutual intelligibility does not exist, the two varieties are generally seen to belong to different individual languages.
Where spoken intelligibility between language varieties is marginal, the existence of a common literature or of a common ethnolinguistic identity with a central language variety that both speaker communities understand is a strong indicator that they should nevertheless be considered language varieties of the same language.
Where there is enough intelligibility between language varieties to enable communication, they can nevertheless be treated as different individual languages when they have long-standing, distinctly named ethnolinguistic identities coupled with established linguistic normalization and literatures that are distinct.
