Gaia-X, a private not-for-profit Association, was established in 2021 with the aim of boosting the European data economy through the creation of common dataspaces. It brings together a diverse range of organizations including large companies, SMEs, developers, technology users, industrial players, and academic members. The main objective of Gaia-X is to align with the EU's Data Strategy and build a common standard for an open, transparent, and secure digital ecosystem. This ecosystem will serve as the foundation for a new model of data infrastructure that ensures safe and reliable data exchange. external-link

Gaia-X Compliance

There are two primary subsystems that make up the Gaia-X Compliance: The first one is the Trust Framework, which is obligatory and confirms the authenticity and accuracy of all service features. The 'Trust Framework' subsystem applies a uniform set of regulations that each participant and service in the Gaia-X Ecosystem must comply with to be considered Gaia-X Compliant. The second subsystem is the Labeling Framework, which is not mandatory and permits the verification of adherence to rule-sets that meet particular market requirements. external-link

Gaia-X Compliance Service
