This paper seeks to address the question of how a DPP can be effectively implemented in the field of engineering, developing a referenced, industry-independent architecture for this purpose. The layers for data, communication, logical architecture, functions, and potential are derived from regulation and practice; integration, interoperability, and validation requirements are discussed using a use case.</jats:p> Cambridge University Press (CUP)2026 eng 2732-527X10.1017/pds.2026.10518 61601-1610 Trienens, Malte, et al. “Towards a Reference Architecture for Digital Product Passports in Engineering.” <i>Proceedings of the Design Society</i>, vol. 6, Cambridge University Press (CUP), 2026, pp. 1601–10, doi:<a href="https://doi.org/10.1017/pds.2026.10518">10.1017/pds.2026.10518</a>. @article{Trienens_Wyrwich_Schörder_Hovemann_Dumitrescu_2026, title={Towards a reference architecture for digital product passports in engineering}, volume={6}, DOI={<a href="https://doi.org/10.1017/pds.2026.10518">10.1017/pds.2026.10518</a>}, journal={Proceedings of the Design Society}, publisher={Cambridge University Press (CUP)}, author={Trienens, Malte and Wyrwich, Fabian and Schörder, Luca and Hovemann, Aschot and Dumitrescu, Roman}, year={2026}, pages={1601–1610} } Trienens M, Wyrwich F, Schörder L, Hovemann A, Dumitrescu R.
