Enhancing the interoperability of calibration certificates

In the framework of digital transformation in metrology the calibration certificates must be electronically transmitted and machine readable. This requires harmonization of schemes, formats, and taxonomies. To improve interoperability of calibration certificates within all the quality system, this work proposes the adoption of a taxonomy developed by NCSLI MII to represent concepts and Consutive Comitees services (CC services) delineated in the KCBD, as an integral part of the context within a calibration certificate. In addition to the machine readability, utilizing the taxonomy offers a more comprehensive description of the context for humans. This paper analyses the proposed taxonomy and study its application to some scenarios of electrical quantities on a Digital Calibration Certificates based on PTB scheme V3.
