Federated Data Spaces as an Enabler for Smart City Services – Logistics Use-Case Example

Innovative technologies enable the collection of Smart City data resulting in a lot of heterogeneous data pools. Linking these leads to the development of more complex services, which enables added value services for citizens. Since the General Data Protection Regulation ({GDPR}) guarantees extensive data rights for {EU} citizens, the linking of the above mentioned data pools becomes quite complicated. In order to accomplish this, a variety of different implementations for Federated Data Spaces are currently being developed. Gaia-X is one of the most relevant Data Space architectures and the Eclipse Data Space ({EDC}) implementation is another. However, they focus on different aspects. Gaia-X solves the problems of data sovereignty and compliant participants and the {EDC} allows the control of data transfer and interoperable data exchange.With this paper, we want to build an easy-to-use Data Space demonstrator ({FedDSGcon}), which combines {EDC} with Gaia-X federation services to take advantage of both technologies. A logistics use-case is used for evaluation purposes, as well as an instruction set to set up {FedDSGcon}.
