What is the Joint Advisory Committee (JAC) for the ISO 639 standards?
The Joint Advisory Committee ISO 639/RA-JAC was established to advise the ISO 639-1 and 639-2 registration authorities and guide coding rule applications (as laid down in the ISO 639 documentation). It consists of six individuals representing ISO member bodies, plus the rotating chairs of the registration authorities as well as up to six observers. The JAC considers applications for new language codes and votes on whether they will be included.
