This deliverable will present the SM4RTENANCE blueprint based on the analysis of embryonic Data Spaces from CATENA-X, MANUFACTURING-X, BAIDATA, SCSN, DFIX already existing in the EU Data
Space ecosystem. The objective will be to identify what is missing to achieve the federation of Data Spaces and their harmonization, to progress towards a unified manufacturing Data Space ecosystem.

This deliverable (D3.1) presents the first technical implementation release of the SM4RTENANCE Data Space Services and Portal. It builds upon the architectural vision and harmonization principles defined in previous work (notably D2.2) and translates them into a coherent set of modular, functional, and compliant services. These services aim to support the secure and interoperable exchange of data across industrial actors, while respecting the sovereignty of participants and enabling the emergence of decentralized business models.
