CADDE

Basic Information

Description

The Cross-domain Architecture for Data Exchange (CADDE) is a Japanese framework designed to facilitate seamless and secure data interoperability across diverse industrial domains. By establishing a standard for sovereign data exchange, it allows organizations to bridge geographical and legislative gaps, which is essential for ensuring global accountability in complex value chains. The framework plays a critical role in verifying environmental metrics, such as Scope 3 emissions and carbon footprints, within international supply chains. CADDE is frequently analyzed alongside the international-data-spaces (IDS) to demonstrate how cross-data space interworking can support the Twin Transition.
