- Abstract
The prototype of a digital machine-readable and machine-actionable calibration certificate (DCC) Digital Calibration Certificate) was already published in 2017 in the PTB-Mitteilungen [S. Hackel, F. Härtig, J. Hornig, und T. Wiedenhöfer, The Digital Calibration Certificate, PTB-Mitteilungen, vol. 127, Bd. 4, S. 7, 2017 [Online]. Verfügbar unter: https://oar.ptb.de/resources/show/10.7795/310.20170403 [Zugegriffen: Jul. 2, 2019].]. The idea is based on the European research project SmartCom (17IND02) [,,Welcome to SmartCom", 2021 [Online]. Verfügbar unter: https://www.ptb.de/empir2018/smartcom/project/ [Zugegriffen: Februar. 15, 2023]; EURAMET-European Association of National Metrology Institutes, ,,Communication and validation of smart data in IoT-networks", EURAMET, 2023 [Online]. Verfügbar unter: https://www.euramet.org/research-innovation/search-research-projects/details/project/communication-and-validation-of-smart-data-in-iot- networks [Zugegriffen: Februar. 15, 2023.] by PTB in 2016 and has been an integral part of PTB's digitization concept since 2017. The DCC offers the worldwide unambiguous identification and storage of the properties of any calibration object and thus does more than just prove metrological traceability. The prototype DCC developed by PTB is based on the XML exchange format and is therefore machine-readable and machine-actionable and future-proof. In addition, all requirements of DIN ISO 17025 [DIN EN ISO/IEC 17025:2018-03, Allgemeine Anforderungen an die Kompetenz von Prüf- und Kalibrierlaboratorien (ISO/IEC_17025:2017); Deutsche und Englische Fassung EN_ISO/IEC_17025:2017, Beuth Verlag GmbH [Online]. Verfügbar unter: https://www.beuth.de/de/-/-/278030106 [Zugegriffen: Sept. 24, 2021].] are considered. For the representation of measured values, a data model based on the SI Units was designed in the SmartCom project and a prototypical XML data exchange format was developed. This format, known as DSI (digital SI [D. Hutzschenreuter u.a., SmartCom Digital-SI (D-SI) XML Exchange Format for Metrological Data Version 2.0.0, 2021 [Online]. Verfügbar unter: https://zenodo.org/record/4709001 [Zugegriffen: Mär. 10, 2022].]) forms the basis for the specification of measurement data in the DCC, among other things. In addition, it can be used for any other exchange of metrological information. All information, including numerical calibration curves, can be transferred directly and automatically from the DCC to digital processes. Cryptographic signatures as a security method ensure the integrity and authenticity of a DCC. All concepts have been discussed, coordinated, and further developed with partners in Europe and the world.
