Digital Product Passports require interoperable product data, reliable exchange mechanisms, and scalable hosting models. In this lecture, Erich Barnstedt from Microsoft explains how an OPC UA-based open-source solution can support the generation, hosting, and exchange of EU Digital Product Passports.
Erich Barnstedt is Senior Director & Architect Industrial Standards in the Corporate Standards Group at Microsoft Corporation and Chair of the OPC Foundation Cloud Initiative. His session was part of the Think WIoT Livestream “DPP in practice” on April 29, 2026.
The lecture focuses on a practical end-to-end architecture for the EU Digital Product Passport. At its core is an OPC Foundation Digital Product Passport solution that combines open standards and open-source components. It connects CEN/CENELEC requirements, OPC UA information modelling, semantic dictionaries, and dataspace-based exchange mechanisms.
A central part of the presentation is the role of OPC UA as a data modelling and interoperability layer. The solution uses OPC UA NodeSets for data at rest and CENELEC JSON for data in transit. It also builds on semantic structures such as the IEC Common Data Dictionary, ECLASS, VDMA OPC UA Companion Specifications, IDTA and Catena-X templates.
The presentation also addresses the broader standards context around the EU Digital Product Passport. This includes CEN/CENELEC JTC 24 work on product identifiers, data carriers, storage APIs, exchange protocols, application programming interfaces and system interoperability. For companies preparing DPP implementations, this standards alignment is essential because product passport architectures must function across organizations, platforms and value chains.
Erich Barnstedt shows how the OPC Foundation Cloud Initiative reference architecture can support DPP deployment scenarios from on-premises manufacturing systems to enterprise cloud environments and downstream product consumers. The lecture also connects the DPP architecture with dataspace connectors and Eclipse Dataspace Connector technology for controlled, cross-company data exchange.
For manufacturers, system integrators, IT service providers, automation vendors and platform providers, the session provides a technical view of how Digital Product Passports can be implemented without relying on closed, isolated platform models. It highlights how open-source components, OPC UA, CEN/CENELEC specifications and EDC-based data exchange can form a practical foundation for scalable DPP systems.
The lecture is especially relevant for stakeholders working on DPP architectures, industrial data spaces, product lifecycle data, battery passports, compliance workflows and interoperable product information systems.
Open standards and interoperable architectures based on OPC UA and CEN/CENELEC specifications form the foundation for scalable, cross-company EU Digital Product Passport implementations.
