Abstract

Calibration certificates are the heart of metrological quality infrastructure and a central element of traceability of measurements. The Digital Calibration Certificate (DCC) is an endeavor to digitalize calibration certificates, developed coordinated by the PTB with the contributions of national and international partners. The DCC is implemented in XML format, and an XSD Schema is developed and maintained by PTB. The DCC schema allows validating the DCCs. Schematron is a schema language which is used to write logical rules for XML files. The PTB’s DCC team has prepared a Schematron validation tool with open-source resources.
