Decentralized Catalogue and Contracting Service (CCS)

The Decentralited Catalogue and Contracting Service act as an inventory, allowing participants to discover, understand, and use available data in an ecosystem. The Federated Catalogue serves as a repository for a Federation, enabling participants to find each other's information and services through Self-Descriptions. The toolbox provides code for groups to create their own Catalogue and includes services for contract negotiations and tracking data transactions, giving participants control over their data usage within the group.
