Exchange of data and data themselves are the very basis of highly automated industrial processes, of science as well as of emerging applications in artificial intelligence and machine-learning algorithms. Data on results of measurements are expressed in terms of a numerical value and a unit. Under the auspices of the Metre Convention, more than 100 States and Economies have agreed upon the International System of Units, the SI, which was substantially revised in 2018 by a resolution of the General Conference of Weights and Measures, the plenary organ established by the Metre Convention. The revised SI is based on defining constants, among them the fundamental constants of nature.
The International Committee for Weights and Measures (CIPM), which directs all metrological work the parties to the Metre Convention decide to carry out in common, now takes the lead to transform the SI into the digitized world via its Task Group on the "Digital SI".
The Task Group is now organizing a virtual workshop to bring together leading experts and groups in digitalization related to metrology and data science in order to exchange ideas about first steps to proceed in this direction aiming at agreeing on basic standards for a "Digital SI" framework.
The virtual workshop will be composed of two parts. Key-presentation sessions accompanied by plenary session are the first part that allow participants to get an insight on actions that are undertaken within various leading organizations regarding data formats, interoperability of data, FAIR principles and Artificial-Intelligence. Discussion are aiming to capture the high-level requirements for using data based on the SI across all organizations involved in, and depending on, the Quality Infrastructure. In the second part, workshop participants are kindly invited to join in panel discussions for truly international exploration of the technical approaches and promote collaboration on an international scale for a "Digital-SI" framework. The exchange on viable strategies and actions in the Quality infrastructure will be supported by breakout sessions to define use-cases for digital measurement data based on the SI.
