deployEMDS Technical specifications report

This technical report presents the outcomes of Task 2.2 of the deployEMDS project, which focuses on specifying the data space architecture and building blocks in line with the European Data Spaces technical framework. As part of Work Package 2, "Deployment of an operational data space across borders", this task builds on the project’s use case requirements and defines the business processes needed for a functional data space to be deployed. To support the selection of the most suitable technical foundation for the deployEMDS architecture, the project team developed a comprehensive methodology. This approach involved translating use case requirements into customer journeys and related business processes, mapping them to essential data space building blocks, and evaluating existing software stacks. The work is conceptually grounded in the Data Space Blueprint developed by the DSSC, which outlines key organisational and technical building blocks for data spaces. Three software stacks were analysed:

• Eclipse Data Space Components (EDC) – a mature, industry-driven open-source initiative offering a reference implementation of a data space connector and the underlying Data Space Protocol

• FIWARE Data Space Connector – an implementation developed by the FIWARE Foundation to connect FIWARE-based technologies to data spaces

• Simpl – a European Commission-driven open-source initiative to support the implementation of Common European Data Spaces
