Concept of the national digital infrastructure for ensuring the uniformity of measurements

This article proposes a concept of a national digital infrastructure for ensuring the uniformity of measurements – a data infrastructure providing end-to-end digital traceability of measuring instruments throughout all stages of their lifecycle. The proposed concept is considered as a systemic foundation for the digital transformation of metrological activities in the Russian Federation and provides for the development of a three-tier architecture consisting of a regulatory and semantic core, a trust infrastructure, and a market of compatible applied digital services. The proposed architecture of the national digital infrastructure is based on the principles of equal conditions for all participants, competitive compatibility, and the economic interest of measuring instrument lifecycle participants in maintaining digital traceability. It involves the use of machine-readable SMART standards, open specifications, a unified semantic data model, and knowledge graphs. The combined application of these elements ensures interoperability of information systems, the formation of semantically consistent data, and creates conditions for the application of artificial intelligence technologies in metrological tasks, including automated data processing and prediction of the condition of measuring instruments. Such an architecture can serve as a basis for the phased implementation of the objectives of the federal project “Technological Leadership in Ensuring the Uniformity of Measurements”. Practical implementation of the infrastructure involves the development of digital profiles for groups of measuring instruments as a semantic foundation for the formation of machine-readable digital descriptions of measuring instrument types, as well as the development of a market for compatible digital platforms, services, and intelligent software agents.
