The DPP Keystone project provides a centralized, harmonized vocabulary for the EU Digital Product Passport (DPP), offering an open-source library of JSON-LD definitions that map semantic equivalencies between various standards like ISO, GS1, and Schema.org. Its goal is to ensure interoperability and lower implementation barriers, particularly for SMEs, by acting as a "Rosetta Stone" for DPP data. The project includes tools like an EPD Adapter for transforming environmental product data into widely recognized formats and uses automated build and deployment processes to maintain an up-to-date, validated resource.
