M4.2: FAIRagro Federated RDI Network: Consolidation of Research Metadata

The FAIRagro Federated RDI Network integrates metadata from heterogeneous research data infrastructures (RDIs) into a unified framework. It addresses the challenges of diverse technologies, inconsistent metadata models, and missing APIs. In 2025, the key contribution is the SQL-to-ARC approach, enabling standardized generation of Annotated Research Contexts (ARCs) and their consolidation within the network. The introduction of the ARC concept itself was first proposed by Jorge García Brizuela et al., while the SQL-to-ARC approach is a subsequent development.
