Six Keynote Presentations on AI & Digital Transformation in Metrology

Six keynote presentations from the third Forum on Metrology and Digitalization (FORUM-MD), held at the BIPM in Sèvres, are now available on the BIPM's official YouTube channel. The recordings cover machine-actionable data, Digital Calibration Certificates (DCCs), and the role of metrology in supporting trustworthy artificial intelligence.

Keynote speakers:

"Metrology brings confidence to measurement data through careful definition of what is being measured, calibration and traceability to national standards, and the evaluation of uncertainty." These same principles can be applied to AI systems — by ensuring test and training data are traceable, that testing addresses clearly defined risks, and that model outputs are accompanied by appropriate uncertainty evaluations. — Louise Wright, Chair, FORUM-MD Task Group on Safe and Trustworthy AI, NPL
"Measurement results are no longer limited to values, units, and uncertainties, but include comprehensive contextual and semantic information. In the real field, this enables more efficient calibration-dependent processes, reduces human error, saves time, and supports advanced applications such as AI-driven analysis, digital twins and many others." — Martin Koval, Czech Metrology Institute (CMI)
"Digital transformation not only boosts trust but also enhances efficiency, even for practical and administrative tasks." — Peter Blattner, Chief Metrology Officer, METAS

A central theme was the alignment of the SI Digital Framework (SIDF), the SI Reference Point (SIRP), and the Key Comparison Database (KCDB) to support consistent, machine-readable exchange of measurement data. Next FORUM-MD meeting: February 2027, BIPM Sèvres.

BIPM · SI Digital Framework

SI Reference Point v1.0.0 Released

Version 1.0.0 of the SI Reference Point has been released by the BIPM as part of the SI Digital Framework — a milestone in the digital transformation of the international measurement system. The service provides Permanent Digital Identifiers (PIDs) for the named SI units, SI prefixes, and defining constants, along with a parsing tool and semantic model for compound units.
