Tracking and viewing modifications in digital calibration certificates
Keywords:digital calibration certificates, provenance, temporal databases, XML, web application
Trust in current and historical calibration data is crucial. The recently proposed XML schema for digital calibration certificates (DCCs) provides machine-readability and a common exchange format to enhance this trust. We present a prototype web application developed in the programming language Links for storing and displaying a DCC using a relational database. In particular, we leverage the temporal database features that Links provides to capture different versions of a certificate and inspect differences between versions. The prototype is the starting point for developing software to support DCCs and the data with which they are populated and has underlined that DCCs are the tip of the iceberg in automating the management of digital calibration data, activity that includes data provenance and tracking of modifications.
