Interoperability

Standardising data exchange

In a data space, participants need to be able to share and exchange data in a standardised way, both within a specific area (e.g., between different stakeholders in traffic management), as well as across domains (e.g., mobility and tourism to improve traffic management in touristic areas). As such, data interoperability is essential as it enables data to be accessible across different formats and platforms. It allows a participant to maximise value from its data and overcome the significant challenges posed by proprietary data assets (company- or sector-specific formats). Data interoperability requires capabilities to enable semantic interoperability – the ability to exchange data with unambiguous, commonly agreed meaning – between participants in a data space. In practice this means enabling participants to specify their (domain specific and cross-domain) semantics, link them to (common) technical interfaces, and record which data was exchanged with whom.

Common, domain independent building blocks

• Data space connectors: Provide a secure gateway for systems and organisations to the EMDS, relating to all building blocks.​ Adhere to a common European data spaces framework for interoperability within a data space and for federation of multiple data spaces.
• Federated services​ (Data sovereignty and trust)​: Enable EMDS interoperability on data sovereignty and trust, both across the federation of mobility data spaces and with other sectoral data spaces. Align policy definition, exchange and enforcement mechanisms.
• Federated data space registry​ (Discoverability)​: Enable discoverability of data services and IT resources, both across federated mobility and logistics data spaces and other sectoral data spaces.​ Align formats for exchanging data services, applications and data models and mappings.
