Traceability in Data Spaces: From Individual Measurements to a Digital Product Passport

Data spaces are digital realms of data and information shared between stakeholders and peer groups. They underpin several developments in sectors ranging from automotive industry, social sciences to governmental networks. Digital traceability of information in data spaces is needed to validate statements about metadata, data quality, and data features. In many cases this also directly translates to metrological traceability of measurements to the SI. The concept and development of digital product passports bring these traceability aspects together to form a tool for a digital quality infrastructure. This paper outlines the general principles of digital metrological traceability based on digital certificates, a digital international system of units, and digital product passports.
