D4Temp — Advanced digital infrastructure for harmonised temperature metrology D4Temp

Project Structure

Six work packages, one shared infrastructure

D4Temp is structured into four scientific/technical work packages (WP1–WP4), a dissemination & exploitation work package (WP5), and project management (WP6) — delivered over 36 months by 17 partners across 14 European countries.

WP1 Lead: SMU 3 tasks · 13 activities

Creating a common basis for the successful implementation of digitalisation tools

WP1 identifies and gathers the standards, practices, resources, and developments relevant to digitalisation in temperature metrology. The findings are consolidated into an implementation plan tailored to NMI/DI structures and disseminated through learning tools and platforms, building a shared knowledge base across the consortium.

WP2 Lead: NSAI 3 tasks · 16 activities

Workflow definition and library development

WP2 establishes the foundation for sharing software solutions across NMIs/DIs — harmonising processes and enabling smart specialisation. It identifies in-scope resources, defines a common database structure, and populates a shared repository with libraries for temperature-related software, designed for ISO 17025, DCC, and FAIR compliance.

WP3 Lead: PTB 2 tasks · 10 activities

Automated digital workflows for temperature calibration

WP3 develops and implements end-to-end automated workflows for digital temperature calibration. It defines harmonised data types and exchange formats aligned with FAIR, Digital SI, and DCC principles; then maps workflows to libraries from WP2 and implements automated digital workflows for contact and radiation thermometer calibration — tested with blackbox methods and producing harmonised DCCs.

WP4 Lead: Random Red 3 tasks · 16 activities

Decentralised architecture for secure and interoperable exchange of DCCs

WP4 develops an EBSI-based decentralised architecture for data immutability and self-sovereign identities — the first application of EBSI in metrology. It integrates this trust layer with the project's digital workflows and DCCs, enabling universally accepted, verifiable calibration certificates across Europe in line with FAIR principles, Digital SI, and the eIDAS ecosystem.

WP5 Lead: UL 2 tasks · 16 activities

Creating impact

WP5 secures the long-term uptake and impact of the project — through dissemination and communication aimed at the metrology community, industry, regulators, and the wider public, and through exploitation activities that handle IP, licensing, and uptake in line with the Grant Agreement and Consortium Agreement.

WP6 Lead: TUBITAK 3 tasks · 13 activities

Management and coordination

WP6 handles the day-to-day management, coordination, and reporting that keep the consortium aligned — covering financial and administrative coordination, periodic project meetings, and formal reporting in line with EURAMET requirements.

How the work packages relate

Building blocks, layered

WP1 sets the common foundation — mapping the digitalisation landscape and producing an implementation plan. WP2 turns that into a shared resource: a common database structure and a repository of libraries. WP3 then composes those libraries into end-to-end automated workflows producing Digital Calibration Certificates.

WP4 adds the decentralised trust layer — an EBSI-based architecture for self-sovereign identities and immutable, verifiable credentials. WP5 ensures the outputs reach the standards bodies, industry, and end users; WP6 keeps the whole consortium aligned.
