IUPAC is committing to support the development and implementation of the SI Digital Framework
The Joint Statement provides a platform for the signatory organizations to come together to indicate their support, in a way appropriate to their particular organization, to the development, implementation, and promotion of the SI Digital Framework as part of a wider digital transformation of the international scientific and quality infrastructure.
The joint statement is part of an ongoing initiative by the International Committee for Weights and Measures (CIPM) and its Forum on Metrology and Digitalization (FORUM-MD) to develop and establish a world-wide uniform and secure data exchange format based on the International System of Units (SI).

Currently, besides IUPAC ten organizations are signatories to JSI, including BIPM (representing CIPM), CIE, CODATA, IEC, ILAC, IMEKO, ISC, ISO, NCSLI, and OIML. These entities share a common focus on metrology while addressing standards development and engaging with global communities such as metrology institutes, universities, and industries. Their collective mission is to establish forward-looking and harmonized definitions within metrology.
The signatories have committed to supporting the development and implementation of the SI Digital Framework as part of a broader digital transformation of international scientific and quality infrastructure. According to Leah McEwen, Chair of the Committee on Publications and Cheminformatics Data Standards (CPCDS), this effort aligns with IUPAC ‘s initiatives to support FAIR digital representation of chemical measurement and data.
