ISO 639-5:2008 "Codes for the representation of names of languages—Part 5: Alpha-3 code forlanguage families and groups" is an international standard published by theInternational Organization for Standardization (ISO). It was developed by ISO Technical Committee 37, Subcommittee 2, and first published on May 15, 2008. It is part of theISO 639 series of standards.
This is alist of ISO 639-5 codes, including the code hierarchy as given in the ISO 639-5 registry.[1] The codeund (undetermined) fromISO 639-2 can be seen as top of the hierarchy (for example,und:aav,und:euq:eu). The hierarchy is not a complete genetic hierarchy; some of the collection codes are based on geography (likenai) or category (likecrp) instead.
ISO 639-5 definesalpha-3 (3-letter) codes, called "collective codes", that identify language families and groups. As of the February 11, 2013, update to ISO 639-5, the standard defines 115 collective codes.[2][3] The United StatesLibrary of Congress maintains the list of Alpha-3 codes that comprise ISO 639-5.[4]
The standard does not cover all language families used by linguists. The languages covered by a group code need not be linguistically related, but may have a geographic relation, or category relation (such asCreoles).
Some of the codes in ISO 639-5 codes are also found in theISO 639-2 "Alpha-3 code" standard.[72] ISO 639-2 contains codes for some individual languages, someISO 639 macrolanguage codes, and some collective codes; any code found in ISO 639-2 is also found in eitherISO 639-3 or ISO 639-5.
Languages, families, or group codes in ISO 639-2 can be of type "group" (g) or "remainder group" (r). A "group" consists of several related languages; a "remainder group" is a group of several related languages from which some specific languages have been excluded. However, in ISO 639-5, the "remainder groups" donot exclude any languages. Because ISO 639-2 and ISO 639-5 use the same Alpha-3 codes, but do not always refer to the same list of languages for any given code, the languages an Alpha-3 code refers to can not be determined unless it is known whether the code is used in the context of ISO 639-2 or ISO 639-5.
| Alpha-3 code | ISO 639-2 type | ISO 639-2 definition | ISO 639-5 definition |
|---|---|---|---|
afa | remainder group (r) | Afro-Asiatic languages | allAfro-Asiatic languages |
alg | normal group (g) | allAlgonquian languages | allAlgonquian languages |
sqj | not defined | not defined | Albanian languages |
The committee draft of ISO 639-5 was issued on February 23, 2005. Voting on the draft terminated on July 5, 2005; the draft was approved.
In 2006, the target publication date for the final standard was set at October 30, 2007. During the approval stage for the standard, the ISO final draft international standard ballot was not initiated until February 8, 2008. Voting ended on April 10, 2008 ("stage 50.60").
The standard was published on May 15, 2008.
Updates were made in August 2008, February 2009, and February 2013.[2]
