The EU Data Governance Act, complementing the Data Act and the Open Data Directive, envisions data spaces—federated ecosystems where organizations share data without surrendering ownership or control. The health data space, the energy data space, the agriculture data space: each is a domain-specific ecosystem with its own governance, its own trust framework, and its own technical standards.
Why data spaces are different. Traditional data sharing relies on a central authority: a data warehouse, a data lake, or a platform that aggregates data from multiple sources. Data spaces have no central authority. Each participant remains the owner of its data, sharing it through agreed protocols and under agreed terms. This is a fundamentally different architecture—federated rather than centralized, protocol-driven rather than platform-driven.
The technical requirements. Participating in a data space requires: a connector that implements the data space protocol, enabling your organization to publish and consume data; a catalog that describes the data you offer, using standardized metadata (DCAT-AP in the EU context); a contract framework that specifies the terms under which data can be used, including restrictions on redistribution and derivative works; and a trust framework that verifies participant identity and authorization.
The organizational challenge. Technical infrastructure is necessary but insufficient. Data spaces require organizational commitment to data sharing: defining what data can be shared, under what terms, and with whom. This requires legal review (to ensure sharing does not violate contractual obligations or data protection law), business review (to ensure sharing creates rather than destroys value), and governance review (to define decision-making processes for data sharing requests).
For procurement. EU government tenders increasingly require data space compatibility. Organizations that can demonstrate a connector, a catalog, and a governance framework for data sharing will be positioned for these tenders. Those that cannot will find themselves excluded from an expanding segment of EU procurement.
Data spaces are not a future technology—they are an active policy initiative with funded pilots across Europe. The organizations that participate early will shape the standards. The organizations that wait will adopt standards that were shaped by others.
