Catena-X

Catena-X is the automotive industry’s data space standard — a numbered library of CX-xxxx specifications published by Catena-X Automotive Network e.V. that define how a supply chain shares part data, carbon footprints, quality records and digital product passports without any participant handing over its data to a central platform. The standards are public and free to read on GitHub, the reference implementation is open source at the Eclipse Foundation, and conformance is certified by nominated third-party assessment bodies. It is the most institutionally complete industry API standard in Europe, and the one whose endpoints an outside developer can never call.
