[2] CODATA exists to promote global collaboration to advance open science and to improve the availability and usability of data for all areas of research.
The CODATA Strategic Plan 2015 and Prospectus of Strategy and Achievement 2016 identify three priority areas: CODATA achieves these objectives through a number of standing committees and strategic executive led initiatives, and through its task groups and working groups.
In order to support the 2019 revision of the SI,[26][21] adopted at the 26th General Conference on Weights and Measures on 16 November 2018, CODATA made a special release that was published in October 2017.
[27][28] It incorporates all data up to 1 July 2017,[21]: 4, 67 [29][30] and determines the final numerical values of h, e, k, and NA that are used for the new SI definitions.
The regular version with a closing date of 31 December 2018[25][27] was used to produce the new 2018 CODATA values that were made available by the time the revised SI came into force on 20 May 2019.
