B2DROP is EUDAT's Enterprise File Synchronization and Sharing (EFSS) service, designed to provide researchers across Europe with a collaborative platform for seamless data exchange, sharing, and real-time collaboration—regardless of research domain or national borders. As part of EUDAT's B2 service suite, B2DROP streamlines data publication and long-term archiving after project completion while integrating with domain-specific services, such as the CLARIN Switchboard for the humanities and social sciences. The premium version of B2DROP offers dedicated storage solutions for research groups or projects, with customizable extensions to meet community-specific requirements. As a core component of the European Open Science Cloud (EOSC), B2DROP supports cross-node use cases, enabling interoperability and collaboration within the EOSC federation. EUDAT, as part of the first wave of EOSC nodes, ensures that B2DROP aligns with EOSC's goals for open and FAIR (Findable, Accessible, Interoperable, Reusable) data management. To simplify access control and group management, B2DROP leverages group membership information from upstream Authentication and Authorization Infrastructures (AAIs). Researchers can manage groups via B2ACCESS (EUDAT's AAI) or any other EOSC-compatible AAI, ensuring flexible and secure collaboration across the European research ecosystem.
