Open, interoperable standards for scalable and trusted data exchange.
A Liaison Agreement with the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (CENELEC) has been announced by The OPC Foundation. This marks an important step forward in the standardisation of Digital Product Passport (DPP) solutions in Europe.*
The collaboration supports the development of interoperable DPP solutions that ensure trusted, semantic rich data exchange, regulatory compliance, and scalable deployments across sector-specific data spaces. By combining the European standardisation framework with OPC UA’s proven interoperability technologies, the liaison contributes to a harmonised and future-proof approach to Digital Product Passports.
Although OPC UA is widely known for secure information transport in automation, its true strength lies in its rich, semantic information modeling capabilities. Through the liaison with CEN/CENELEC JTC 24, OPC UA will be used and extended with standardised Digital Product Passport data models and interfaces, supporting system-agnostic and interoperable DPP implementations.
Commenting on the cooperation, Bmstr. Ing. Otto Handle, Convenor of CEN/CENELEC/JTC 24 WG4 – Digital Product Passport – Interoperability, stated: “One aim of the standardisation work of JTC 24 is interoperability beyond all system borders. The standardisation request of the European Commission clearly states that the DPP shall be system agnostic and vendor independent. Integration and Interoperability with the full DPP system shall be possible for any software and any system according to these standards. Therefore, we highly appreciate and welcome OPC Foundation in the Liaison and look forward to the modelling of DPPs with OPC UA and integration of the specified JTC24 API and data models, as well as shop floor integration with OPC UA-enabled embedded systems as DPP data sources.”
Erich Barnstedt, Microsoft, liaison officer for the OPC Foundation “This liaison ensures that Digital Product Passports (DPPs) are built on truly open, standardised, and interoperable foundations. By contributing the very successful OPC UA modelling capabilities to DPPs, including an open-source reference implementation, we help enable seamless integration of DPP data across vendors, platforms, and system layers. What is remarkable is the timeline in which this was possible: From initial concepts to finished implementation, the OPC Foundation only took 2 weeks.”
The Liaison Agreement is established for an unlimited period, contingent on the OPC Foundation’s continued participation in the work of JTC 24. It reflects a shared ambition to advance open, interoperable, and internationally aligned standards that support the European Union’s digital transformation and sustainability goals.
By working together, CEN, CENELEC, and the OPC Foundation reaffirm their commitment to ensuring that Digital Product Passports are built on robust, open standards — enabling innovation, interoperability, and long-term value across industries.
