Inter-Catalogue Synchronization

The system of Federated Catalogues comprises “official” GAIA-X Catalogues as well as Ecosystem-specific Catalogues (e.g., for the healthcare domain) and even company-internal Catalogues with private Self-Descriptions to be used only internally. Self-Descriptions in a Catalogue are either loaded directly into the Catalogue or exchanged from another Catalogue by an inter-Catalogue synchronization interface.

Self-Descriptions can be marked by the issuer as “non-public” to prevent that they are copied to a public Catalogue by a third-party that received the Self-Description JSON-LD file over a private channel.
