EONA‑X Data Space
Data-sharing for transport, mobility & tourism
EONA‑X is a neutral, non‑profit, cross‑sector alliance that builds and operates a European data space for mobility, transport and tourism. It follows GAIA‑X principles and promotes a sovereign, reliable and decentralised digital infrastructure so organisations can publish, discover and use data and services with full control. Founded in 2022 by seven leading partners: Groupe ADP, Amadeus, Air France‑KLM, SNCF, Renault Group, Aéroport Marseille Provence and Accor.
Governance & mission
- Neutral association focused on responsible data sharing and new cross‑sector services.
- Open source, interoperability and European governance at the core.
- Data sovereignty preserved: data stays with its owner and is shared under agreed policies.
Community & momentum
EONA‑X convenes large groups, SMEs, startups, research bodies and public institutions across Europe. The ecosystem grows through working groups, EU projects and pilots that turn data into operational services.
Key use cases
Paris 2024 Olympic Games mobility coordination:
unified real‑time data from airports, airlines, rail and tourism to move tens of thousands of guests while protecting everyday flows.
CyclOps (French Alps):
visitor‑flow management combining tourism, transport, weather and holiday calendars to anticipate pressure points.
Gen4Travel:
an autonomous AI travel assistants framework that allows use cases such as incidents detection (delays, cancellations), proposes options with consent, executes changes and synchronises related services (hotel, transfer, activities) in minutes.
Technology platform
- Decentralised architecture: no centralised data lake; data remains at source with policy‑based sharing.
- Decentralised catalogue: discover and share data products; find partners to build use cases.
- Trust services: identity and verifiable credentials, governed rulebooks and machine‑readable contracts.
- Connector‑as‑a‑Service (CaaS) & federated catalogue: quick onboarding for users, networks and white‑label data spaces (sub-domains) while staying interoperable with the wider EONA‑X ecosystem.
- Standards‑aligned: GAIA‑X lighthouse, state‑of‑the‑art technologies and open‑source components; designed for cross‑dataspace interoperability.
What this enables
- Seamless multimodality and disruption handling across airlines, rail, local mobility, hotels and activities.
- Operational efficiency in logistics and transport coordination.
- Destination intelligence for more resilient and sustainable tourism.
- Faster innovation for members via reusable components, shared semantics and common rulebooks.

Operational stage.
EONA-X is operational: the infrastructure is live, multiple use cases are in production with dozens more underway, and the community is expanding. The next step is integrating Gen4Travel (the travel AI agentic framework) and MyTravelConnect (the traveler identity & consent wallet).
