The development of the unified meta data format for the exchange of measurement data in ICT applications and its implementation using XML is part of the research project EMPIR 17IND02 (title: SmartCom). This project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme.

This data set provides 2014 CODATA defining constants using the XML scheme based on the Digital-SI (D-SI) data model that enables a machine-readable transmission of metrological data in digital applications.
