D4Temp — Advanced digital infrastructure for harmonised temperature metrology D4Temp
WP3

Work Package 3

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.

Tasks & activities

Breakdown of work

2 tasks · 10 activities
Task 3.1

Data harmonisation

Months 1–14

Defines appropriate, harmonised data exchange formats in alignment with existing data hierarchies and ontologies — supporting the digital transformation of metrology and the adoption of FAIR, Digital SI, and DCC principles.

Activities (3)

A3.1.1

Data types & exchange formats

Deadline: M8

Identifies appropriate data types and defines data exchange formats (XML, JSON, etc.) for communication between participants and with the libraries from A2.3.1–A2.3.4 — aligned with existing hierarchies, FAIR, Digital SI, and DCC.

Participants: NSAI PTB JV SMD UNIBL TUBITAK BFKH VINS UL Random Red ISTE
A3.1.2

Discrepancy analysis & guidelines

Deadline: M14

Uses typical participant datasets to identify major discrepancies vs. the database design and exchange formats, then proposes guidelines to remove these discrepancies and shares them across participants.

Participants: PTB NSAI TUBITAK JV VINS IMBIH ISTE
A3.1.3

Harmonised DCC example

Deadline: M12

Compares existing DCC formats for temperature measurements in use and produces a harmonised DCC example that also informs the digital credential structures developed in WP4.

Participants: PTB CEM TUBITAK BFKH ISTE
Task 3.2

Automated workflow implementation

Months 12–36

Implements new automated digital workflows that allow participants to set up robust and tested digital calibration infrastructure, generating harmonised DCCs as report format.

Activities (7)

A3.2.1

Workflow-to-library mapping

Deadline: M18

Maps the workflows from A2.1.3 to the libraries developed in A2.3.1–A2.3.4, identifying where middleware (custom adapters or scripts) is needed to connect libraries and database for specific participants.

Participants: CMI TUBITAK FSB BFKH VINS ISTE
A3.2.2

Open-source integration template

Deadline: M24

Uses open-source tools to provide an integration and data-exchange template for the mapped libraries — emphasising automation. Drafts a paper on the resulting middleware approach.

Participants: PTB FSB ISTE SMD TUBITAK BFKH VINS
A3.2.3

Contact thermometry workflow implementation

Deadline: M30

Selected participants implement end-to-end software workflows to streamline contact thermometry (PRT) calibration; others perform partial integration — based on the templates from A3.2.2.

Participants: IMBIH UNIBL SMD NSAI TUBITAK BFKH VINS UL CMI ISTE
A3.2.4

Radiation thermometer workflow implementation

Deadline: M30

JV implements an end-to-end automated workflow for radiation thermometer calibration; NSAI and PTB perform partial integration — demonstrating how libraries combine into a production-ready calibration application.

Participants: JV NSAI PTB
A3.2.5

Blackbox testing — contact thermometry

Deadline: M33

Verifies the contact thermometry implementation from A3.2.3 in parallel with the EBSI capability tests in A4.3.4 — blackbox testing inputs/outputs from supplied data through to the resulting DCC.

Participants: JV CEM UL
A3.2.6

Blackbox testing — radiation thermometry

Deadline: M33

Verifies the radiation thermometer implementation from A3.2.4 in parallel with A4.3.4 — blackbox testing inputs/outputs from supplied JV data through to the resulting DCC.

Participants: UL CMI FSB IMBIH
A3.2.7

Comprehensive workflow documentation paper

Deadline: M35

Compiles comprehensive documentation (including UML diagrams) for the workflows developed in A3.2.2 and implemented in A3.2.3/A3.2.4, and prepares a peer-reviewed paper.

Participants: PTB TUBITAK JV FSB SMD ISTE UNIBL IMBIH VINS UL Random Red
