Rainbow is a Rust-based Dataspace Agent implementation developed by the GING research group at UPM, designed to enable secure data sharing and subscription services between entities in a decentralized manner. It provides a complete end-to-end solution including SSI authentication, DCAT3-compatible catalog management, contract negotiation, and data transfer capabilities, all built with a multi-protocol orientation and dynamic stack architecture. This project is aimed at developers and organizations looking to participate in interoperable data ecosystems while maintaining digital trust and security through self-sovereign identity and policy-compliant data exchanges.
