The digital transformation of agriculture has generated vast heterogeneous datasets from sensors, machinery, and administrative systems; however, interoperability and data sovereignty remain critical challenges. This study presents an IDS-compliant Agricultural Data Space tailored to the Italian context, integrating regulatory frameworks (General Data Protection Regulation, Data Governance Act and Data Act) with the International Data Spaces (IDS) Reference Architecture Model. The study addresses key barriers to data sharing, including technical fragmentation, governance gaps, and economic incentives, by mapping Italian agricultural data flows onto the five-layer IDS model. Policy-based usage control is implemented through machine-enforceable Open Digital Rights Language policies, enabling farmer-centric data sovereignty. Three use cases, namely administrative Common Agricultural Policy (CAP) declarations, machine-generated data portability, and agri-food supply-chain traceability, demonstrate how structured and interoperable data exchange can reduce redundancy, mitigate vendor lock-in, and support sustainable agri-food systems. The findings highlight the feasibility of IDS-driven solutions in real-world agricultural ecosystems, emphasizing the need for sector-specific policy templates and scalable governance mechanisms. This work contributes to the development of the Common European Agricultural Data Space by bridging institutional, technical, and regulatory gaps.
