ISO 639
ISO 639 is a set of codes that stand for languages. These have various uses including in locale data? and tagging web content.
There are several parts, some adopted, some in the process of planning. These are summarized in the table below (which is an updated version of that in section 6 the Document surveying the localisation situation in Africa).
