Trusted data for trusted AI
The community building Europe's data infrastructure
Prometheus-X is a large, cross-sector open source, co-governed community building the lightweight, easy-to-deploy stack for European data spaces — enabling trusted data sharing and trustworthy AI from cloud to edge, with data sovereignty built in by design.

What you build alone costs you twice as much.
What you build together becomes a standard.
As the world navigates environmental, energy, demographic and AI-driven change, trusted and interoperable data infrastructure is what lets people and organisations innovate at scale. Prometheus-X provides that infrastructure as open source digital commons — interoperable with leading stacks like EDC, SIMPL and FIWARE, and co-built by a community that pools investment instead of duplicating it.
Shape the standards
As an official Data Space Support Center expert active in DSIF and Gaia-X working groups, your contributions feed directly into the frameworks governing European data exchange for the decade ahead.
Reduce costs
Every shared component and validated ODRL policy is something you don't rebuild. Investment is pooled across the ecosystem, so each actor contributes a fraction and accesses the full stack.
Accelerate deployment
Data spaces built on Prometheus-X reach production 6–18 months faster. Standards are already implemented, cross-data-space tests already done. You start from a certified baseline, not from scratch.
Three ways to contribute. One ecosystem that benefits from all three.
However you join, you gain access to the whole stack — and your work compounds value for every other member.
Axis 1 | Policy & Legal Commons
ODRL Registry · Rulebook · Contract Manager
Machine-readable governance rules, validated by legal experts and reusable across sectors. Stop re-inventing compliance for every new exchange.
You gain: a library of pre-validated policies, contract negotiation in minutes not days, and GDPR / Data Act / DSA compliance by default.

Axis 2 | Core Data Space Components
Catalogue · Contract · Connector · Consent · Identity · Orchestrator
Everything you need to run a data space, production-ready. Because the components are shared and co-governed, interoperability with other data spaces comes for free.
You gain: 6–18 months saved vs. building from scratch, and no custom integration work.

Axis 3 | Advanced Building Block
Anonymisation · Trusted AI · Semantics · Federated analytics
The innovation layer — advanced capabilities co-developed by the community and available to every member. High R&D value at a fraction of solo investment.
You gain: Everything you need to run a data space & natural interoperability — shared components = no custom integration.

Prometheus-X is co-funded
by the European Union and France
This project is aligned with the Digital Europe Programme which is investing 7+ billion euros to allow the European Union, its member states, organisations, and citizens to have data sovereignty thanks to an innovative and decentralised data infrastructure; manifested through the European common data spaces and the SIMPL smart middleware platform.
This project aims to create innovative building blocks that will enable this decentralised infrastructure. It also helps finance sectoral use cases to apply those building blocks to solve real issues organisations and people are facing so as to ensure their value and adoption. This funding is needed as organisations will not finance this innovation on their own, especially in the education and skills sector which is largely composed of public actors and SMEs.
European Union
The European Commission is co-funding the data spaces and infrastructure construction through the Digital Europe program.
France Relance
Prometheus-X is co-funded through the France Relance program (Appel à Projet "ATF : Plateformes numériques et mutualisation de données pour les filières").
