A data space is a decentralized, federated infrastructure that facilitates the secure and trustworthy exchange of data between multiple participants. Unlike centralized data lakes or platforms, a data space preserves data sovereignty, meaning the data owner retains complete control over who can access their data and under what conditions. It relies on common governance frameworks, shared standards, interoperability protocols, and trust services to enable a fair and competitive data economy.
The demo models a concrete EHDS secondary-use scenario: a clinical research organisation wants to run a drug-repurposing study using synthetic patient data held by a hospital, with access governed by a Health Data Access Body. All five layers of this scenario live in a single Neo4j knowledge graph.
