D3.4 – xShare toolbox for data portability under GDPR

Deliverable D3.4 presents the refined modular architecture and updated xShare toolbox enabling GDPR-aligned health data portability and interoperability under EHDS. It introduces open-source tools such as the CDA2FHIR converter, visualization utilities, and synthetic data support, validated through IHE Plugathon-style testing. This interim version lays the foundation for full interoperability and future certification, while identifying areas, such as consent management, that require further development.
