The Digital Product Passports (DPP) from the Ecodesign for Sustainable Products Regulation (ESPR) aims to establish an interoperable and potentially distributed network of product and manufacturing information to promote traceability of products and materials, together with their circularity and sustainability performance. However, while standardization efforts are ongoing (e.g., DaCapo and CIRPASS-2 projecs), there is currently no widely adopted implementation for DPP data exchange and formatting, and the space is still dominated by commercial solutions. This limits expandability, transparency in the system implementation and the standardization of DPP creation. In this work, we present our early stage and ongoing work on the architecture development for an open data exchange protocol for DPPs. We propose a structured clustering of the information needed for the DPP, distinguishing between required and optional type. In addition, we show how enterprise information systems and third-party software such as LCA tools may interact with DPPs as data holder and consumer. We further discuss implications of such protocol from the perspective of governing product sustainability and circularity data, while fulfilling enterprise requirements.
