Data Spaces Hub Luxembourg

About Gaia-X Luxembourg

Luxembourg’s gateway to trusted, sovereign, interoperable data ecosystems

The Data Spaces Hub Luxembourg is the national contact point for digital data ecosystems topics. We support organisations in Luxembourg to navigate, build, and join Data Spaces — infrastructures that enable secure and controlled data sharing between participants, running on trusted sovereign cloud infrastructures, — guided by European principles and governance.

What is a data space?

Federated ecosystems for trusted data collaboration

A data space is an infrastructure that enables secure and controlled data sharing between participants, while allowing them to retain full control over their data. It is based on shared rules, standards, and governance frameworks that ensure trust, legal compliance, and interoperability across sectors.

What does it mean concretely ?

• Data remains under each participant’s control; there is no central “data lake.” 
• Shared rules, standards and governance frameworks ensure trust and legal compliance. 
• Supports cross-sector data use across domains such as : health, mobility, energy, finance, research

A data space is an infrastructure that enables data to be used securely, interoperably, and under the control of its owners.

Data Spaces building blocks

Guiding principles for building trustworthy data spaces

Data Spaces are designed according to internationally recognised principles (DSSC v2.0, 2024), ensuring trust, interoperability, and value for all participants, including :

These elements ensure trust, transparency, and interoperability across participating organisations. 

Data is powerful, but on its own, it’s not enough. To unlock its full potential across borders, sectors, and systems, we need trusted frameworks — ones that ensure secure, fair, and transparent exchange.

The Data Spaces Hub Luxembourg

Your Gateway to Data Spaces and Cloud Services

The Data Spaces Hub Luxembourg acts as a facilitator and connector in Luxembourg and Europe. Managed by LNDS, and supported by LuxInnovation, our mission is to help organisations understand and adopt Data Spaces, align national priorities with European initiatives, and promote cross-sector collaboration.

Our primary roles are to:

• Link / Connect local stakeholders to European Data Spaces ecosystems, resources and frameworks
• Align Luxembourg’s strategic objectives in areas like HealthTech, Industry 4.0, and finance with European data space priorities.
• Promote collaboration to build and participate in secure, interoperable data spaces.
• Support organisations in understanding and adopting standards and frameworks for their cloud services and data-driven projects (e.g. Gaia-X principles).

Trusted data spaces are not just technical challenges — they are social and political commitments. They ensure that data, AI, and digital innovation serve the public good.

Luxembourg’s Data Collaboration in action

Luxembourg is at the forefront of developing collaborative data ecosystems. While the nation has a strong portfolio of data-sharing initiatives like Entrust, Clinnova and MMUST+, these projects represent the wider national ambition for data collaboration.

The first national project actively pursuing Gaia-X compliance is the DataSpace for Health (DS4H). This flagship project aims to create a trusted environment for health data sharing, leveraging the Gaia-X framework to ensure security, sovereignty, and interoperability. DS4H serves as a real-world example of how these principles can be applied to drive innovation in a critical sector.
