EOSC-ENTRUST publishes European TRE network blueprint and interoperability framework

The EOSC-ENTRUST project aims to enhance European interoperability for sensitive data access and analysis. The project has published the first version of its European TRE network blueprint and interoperability framework (the ENTRUST Blueprint), which is available on Zenodo.

A minimum set of requirements for the Blueprint was defined during a Requirements and Capabilities Workshop in May. During the workshop, a conceptual description of the Blueprint was also mapped out, along with agreed terminology. This led to a draft roadmap which was published in June.

The roadmap is divided into three phases. In each phase, the project will release a version of the blueprint with updates based on project outputs:

  • Phase 1 (2024): Year one Blueprint to identify blueprint requirements and map to existing TRE capabilities
  • Phase 2 (2025) – Year two Blueprint to develop and validate key components of the blueprint
  • Phase 3 (2026) – Year three (final) Blueprint
Phase 2 blueprint



An Evaluation and Adoption Workshop in September then built on the initial requirements, with a specific focus on the interoperability, governance and capability aspects to enable federated sensitive data access and analysis.

The first ENTRUST Blueprint includes a draft architecture specification and glossary. Requirements for TRE interoperability were further detailed by comparing the capabilities of existing TREs to the DARE-UK Federated Architecture Blueprint. The proposed architecture fits existing European TRE provider architectures and supports all driver requirements while maintaining the safe principles for sensitive data research. The early definition of architecture, terminology and capabilities in the blueprint will enable the alignment of EOSC-ENTRUST technology development and use cases.

Along with the Blueprint, the project has also published preparatory information which will be used to develop training material, and a first version of the TRE Provider Catalogue describing TRE provider interoperability capabilities.

During 2025, EOSC-ENTRUST project partners will hold a validation workshop to evaluate the Blueprint and a second requirements and capabilities workshop to develop it further. This process will be repeated in the third year of the project, resulting in a final version of the Blueprint which reflects the needs of a wide range of stakeholders.
