Born from Gradiant's research into data spaces, XDATASHARE is the platform for creating and operating federated, sovereign data spaces. Publish, negotiate and transfer data assets under your own rules, with decentralised identity and end-to-end traceability — all built on open European standards.
Sharing data between organisations often means giving up control. XDATASHARE resolves that dilemma.
Data value chains are held back by a lack of trust: who can access what, under which conditions and with which safeguards? Centralised solutions create dependency, silos and regulatory risk.
XDATASHARE provides the essential software components for creating a data space compliant with the specifications of the IDSA (International Data Spaces Association) and Gaia-X. It is based on the Eclipse Dataspace Components (EDC) connector, the open-source reference implementation.
The result is a data exchange in which every participant retains full sovereignty over its assets, defines its own policies and maintains trust without an intermediary controlling the data.
XDATASHARE is the result of Gradiant's research into data spaces: years of applied R&D transformed into production-ready technology.
Manage participants and credentials, configure use cases and review data space traceability. No console or configuration files.
Browse the data space catalog, manage your assets and define reusable contracts and policies to share data with control.
Everything you need to participate in Europe's data economy, without reinventing the infrastructure or becoming tied to a single provider.
Your data never leaves your control. You decide who can access each asset and under which policy, evaluated during every negotiation and throughout the transfer.
Communication through DSP, DCP and DCAT. Compatible with any participant in the IDSA and Gaia-X ecosystem, without bespoke integrations.
Decentralised identities (DIDs using the did:web method) and W3C Verifiable Credentials 2.0. Identity and compliance are proven, not assumed.
The Participant Portal provides a graphical interface for browsing the catalog, negotiating contracts and transferring data. No technical expertise is required to operate the data space.
Deployed on Kubernetes and independent of the underlying technology. It runs on premises or in the cloud and integrates with your storage systems.
Built on the EDC framework (Apache 2.0 licence), the reference implementation maintained by the community. No dependency on a proprietary provider.
Every data asset follows a policy-governed flow compliant with the Data Space Protocol. Push and Pull are two ways of delivering the same agreement.
The provider defines an asset and its access and contract policies, then publishes it in the catalog (DCAT).
DCAT · AssetThe consumer browses the catalog and finds the offers whose policies it satisfies.
Catalog OfferThe contract is negotiated through DSP. The policy engine evaluates the verifiable credentials.
Contract NegotiationBoth parties sign a Contract Agreement that enables and governs the transfer.
AgreementThe Data Plane delivers the asset over HTTP in Push or Pull mode, with real-time monitoring.
Push / Pull · EDRHealthcare, industry, mobility and energy ecosystems that need to share data securely across organisations.
European common data space initiatives aligned with Gaia-X and data regulation.
Operators seeking to offer a turnkey data space to their customer ecosystem.
Teams that monetise or exchange data assets while maintaining regulatory compliance.
Each organisation deploys its own connector and portal. The Data Space Authority governs identities, participants and shared trust.
Resource management, DSP contract negotiation with its own policy engine, and catalog and transfer control. The API is protected by an API key.
Secure HTTP transfer in Push mode, a proxy for Pull downloads, and monitoring of active transfers against the agreed policies.
Management of verifiable credentials (W3C VC 2.0), identification through DID did:web, and credential exchange using the Eclipse DCP 1.0 standard.
XDATASHARE is not a black box: every layer uses open, verifiable protocols aligned with the European data strategy.
Public and private organisations trust XDATASHARE to build sovereign data spaces, particularly in the healthcare sector.

Identity and trust for exchanging data between organisations. Gradiant is researching digital identity and participant descriptions in relation to Gaia-X, a challenge that XDATASHARE addresses with decentralised identities and verifiable credentials.
Learn about the project ↗Data spaces created with XDATASHARE are ready to join the Data Space Trusted List managed by CRED (Spain's Data Spaces Reference Centre), the official registry that identifies data spaces in Spain which pass its technical, interoperability and governance assessments in accordance with UNE Specification 0087:2025.
This includes Global HDS, a data space built on XDATASHARE.
