An IUPAC project (apparently in collaboration with CODATA and CIPM, which makes it very official).

• Units of Measure for Humans and Machines, released in Oct 2020
• Digital Representation of Units of Measure in Chem. Int., vol. 42, no. 4, 2020, pp. 36.
• What's the future of digital chemical units?, presentation by Stuart Chalk at ACS Fall in Aug 2021.
• Stop squandering data: make units of measurement machine-readable in Nature vol. 605, 2022, p. 222-224.

Other IUPAC projects on digital standards. Of particular interest to us are Machine-accessible periodic table and Development of a standard for FAIR data management of spectroscopic data.

With the increasing focus on open science and FAIR data, IUPAC is focusing effort toward the development of digital standards for chemistry. Its Committee on Publications and Cheminformatics Data Standards (CPCDS) has compiled this page with IUPAC resources.

A commendable effort!
