Module:Language/data/ISO 639-2/make
Reads a local copy of data from the table at Codes for the Representation of Names of Languages, extracts the ISO 639-2 codes, names, and ISO 639-1 synonyms. There are two functions in the tool: ISO_synonym_extract() and ISO_2_name_extract().
Usage
To use this tool:
- open a blank sandbox page and paste either or both of these
{{#invoke:}}s into it at the top:- for use in Module:Lang/ISO 639 synonyms:
{{#invoke:Language/data/ISO 639-2/make|ISO_synonym_extract|file-date=YYYY-MM-DD
- for use in Module:Language/data/ISO 639-2 (-2T only) and Module:Language/data/ISO 639-2B:
{{#invoke:Language/data/ISO 639-2/make|ISO_2_name_extract|file-date=YYYY-MM-DD– creates separate tables for 639-2T and for 639-2B
- for use in Module:Lang/ISO 639 synonyms:
- go to the current Codes for the Representation of Names of Languages. Copy the content of the table on that page and paste it into the sandbox page below the
{{#invoke:}}. - click Show preview
- wait
- get result
require('Module:No globals');

{{#invoke:Language/data/ISO 639-2/make|ISO_synonym_extract|file-date=2013-01-11}}
reads a local copy of data from the table at http://www.loc.gov/standards/iso639-2/php/English_list.php, extracts
the ISO 639-2 (or 639-2T) codes that have equivalent ISO 639-1 codes and creates a table to translate 639-2 to 639-1.
ISO-639-3 uses 639-2T codes
useful lines in the source table have the form:
<English name>\t<all English names>\t<all French names>\t<639-2 code>\t<639-1 code>\n
where:
<English name> is primary English name (not used here); one of <all English names> so duplicates code listing
<all English names> is all of the English names (not used here)
<all French names> is all of the French names (not used here)
<639-2 code> is the three-character ISO 639-2 or 639-2B/639-2T language code; when 639-2T present, use that code
<639-1 code> is the two-character ISO 639-1 language code synonym of the -2 code (if one is defined)
like this (with synonym):
Abkhazian Abkhazian abkhaze abk ab
or (without synonym):
Achinese Achinese aceh ace
