A data Space is a place where value is generated around data through its voluntary sharing within an environment of sovereignty, trust, and security. The data space makes it possible to define who can access which data and under what conditions, thus enabling the deployment of different use cases that meet diverse business needs. The data space operates as an open and heterogeneous environment of data product providers and consumers, without dominant players and without disproportionate entry or exit barriers. A data space is not a single platform, but a set of open-source components (‘building blocks’) that follow specifications such as Gaia-X, IDSA and DSSC, and comply with regulations such as the GDPR.
