{{#invoke:Language/name/data/ISO 639-3 data extraction tool|ISO_639_3_extract|file-date=20170217}}

reads a local copy of iso-639-3_Name_Index_YYYYMMDD.tab where (YYYYMMDD is the release date).  Download that file
in zip form from http://www-01.sil.org/iso639-3/download.asp (use the UTF-8 zip)

useful lines in the file have the form:
	<id>\t<name>\t<inverted name>\n
where:
	<id> is the three-character ISO 639-3 language code
	<name> is the language 'name'
	<inverted name> is the language in  'last-name, first-name(s)' form; this part ignored
	
	like this:
		aaq	Eastern Abnaki	Abnaki, Eastern

when a language code has more than one name, the code is repeated for each additional name:
	rar	Cook Islands Maori	Maori, Cook Islands
	rar	Rarotongan	Rarotongan
