Description
RADAR is a generic research data repository developed and operated by FIZ Karlsruhe. Through many years of productive operation, it has reached the highest technology readiness level (TRL 9), providing trustworthy publication, long-term preservation, and FAIR sharing of research data. Its established core functionalities - including DOI registration, role-based collaborative workflows, embargo and review options, standardised interfaces, and long-term bitstream preservation - provide a reliable foundation for community-specific research data services. This foundation can be extended through configurable repository components and the integration of Base4NFDI services.
Designed as adaptable repository software and an operational platform, RADAR can be tailored to the requirements of different research communities. This approach is already realised through RADAR4Chem, RADAR4Culture, RADAR4Memory and RADAR4ING, demonstrating its applicability across different research domains. RADAR4ING additionally illustrates RADAR's flexibility with respect to deployment models. As a local repository instance, it is operated on community infrastructure while being technically maintained by FIZ Karlsruhe.
Our poster illustrates how these community-specific repository services are realised through modular repository components and the integration of Base4NFDI services. Examples include:
• Community-specific metadata: Support for configurable metadata schemas (e. g. XSD or JSON), enabling discipline-specific metadata models while preserving interoperability with generic repository services.
• Research tool integration: Standardised REST APIs enable interoperability with community research tools, for example by connecting the Chemotion Electronic Laboratory Notebook with RADAR4Chem.
• TS4NFDI: Integration of terminology services through a completed Base4NFDI incubator project, providing ontology-driven metadata annotation, discipline-specific terminology collections, type-ahead support, enriched dataset landing pages and improved semantic interoperability.
• DMP4NFDI: Connecting discipline-specific RDMO services (e. g. RDMO4Chem and RDMO4Culture) with RADAR via REST APIs and XML-based metadata exchange through an ongoing Base4NFDI incubator project.
• IAM4NFDI: Identity and Access Management integration via the RegApp system, supporting single sign-on for RADAR4ING and RADAR4Chem, followed by collaborative role and rights management for virtual organisations.
• KGI4NFDI: Registration of the RADAR Knowledge Graph, making its metadata accessible through the KGI Registry and a public SPARQL endpoint.
• Jupyter4NFDI: Participation in an ongoing Base4NFDI incubator project, demonstrating the interoperability of RADAR4Chem with Jupyter notebooks through its REST API and public SPARQL endpoint to support data discovery, retrieval and reuse.
• Accounting4NFDI: Evaluation of potential integration scenarios.
The implementation experience gained across these community-specific services demonstrates the adaptability and flexibility of the RADAR repository software and platform as an established, high-TRL solution for multiple research communities. It provides a blueprint for further NFDI consortia and research communities seeking to set up their own repository services.
By building on RADAR's mature software, proven operational model, and modular integration of Base4NFDI services, communities can focus on their domain-specific requirements instead of developing repository infrastructures from scratch. As a robust, resilient, and operationally proven platform, RADAR is well positioned to contribute to future federated research data infrastructures within the NFDI and the European Open Science Cloud (EOSC).
