HIS Registry Of Language Varieties (ROLV)

Halaman ini belum terdapat pada Bahasa Indonesia.

This registry defines standardized codes used for identifying the language varieties of the world. It is part of the Harvest Information System (HIS).

The previous adopted standard was called HIS Registry of Dialects (ROD).

The Editor and Steward of the Registry Of Language Varieties is Allan Starling.

Overview

The function of the Registry is to:

  • Identify and verify specific varieties of given languages defined by ISO 639-3
  • Provide unique, standardized codes for these varieties

Contents of the Registry

The Registry contains a set of varieties of living languages. A code in this set represents a unique variety of a language.

By definition the scope of a language variety code is always a smaller group of speakers than the group represented by the assigned language as a whole.

Two codes are provided:

  • ROLV Code. This is a standardized five-digit code (including leading zeros, when necessary) for uniquely referring to a particular variety.
  • BCP-47 code. IETF Language Tags defined in BCP-47 identify not only the language variety, but also script and spelling conventions. This scheme enables users to tap into a wider set of language research and tools.

Information about the varieties is available in the Global Recordings Network website. Users have full access to those descriptions as follows:

Changes to the Registry

Language varieties may be added or retired from the registry as a result of the following:

  • The International Organization for Standards (ISO) has dropped, divided, merged, or retired an ISO 639-3 code.
  • The ISO has generated a new code.
  • An item is determined to be a duplicate of another item.
  • A new language variety has been identified

Verification of language-related data

Data can be verified as language varieties by any of the following:

  • Has audio/video recordings.
  • Has literature in any form of media, including Bible translations.
  • Is described in the Ethnologue, but not just in a list of names.
  • Is adequately described in Wikipedia, Joshua Project, Glottolog, Google Search, or similar references.
  • Has a documented percentage intelligibility with another variety.
  • An individual or organization working among the language variety has made a documented request for an ROLV code.
  • Changes are reported by qualified field workers.

Language Varieties may have differences in any or all of vocabulary, grammatical construction, idioms, or marked accents. Differences may also be marked by religious or social prejudices.
