Working Group 2 (WG2) of the Joint Committee for Guides in Metrology (JCGM) has responsibility for maintaining the International Vocabulary of Metrology (VIM).

A corrected version of the third edition of the International Vocabulary of Metrology – Basic and General Concepts and Associated Terms was published in 2012 (JCGM 200:2012), and an "Annotated VIM3" (formally VIM Definitions with Informative Annotations) was published on the BIPM website in 2014. New annotations are added as and when they are approved by the Working Group.
