IDS RAM 5 will become a more practical and flexible reference for building data spaces

DESCRIPCIÓN

IDSA has published a new article outlining what the IDS Reference Architecture Model 5 (RAM 5) will look like, the next generation of its architectural framework for data spaces. Compared to the more conceptual and monolithic approach of RAM 4, RAM 5 adopts a modular, capability-based model designed to address the realities of today’s data spaces, which operate in production environments, across sectors and with multiple providers.

RAM 5 is structured around a core architecture complemented by topic-specific papers on identity, semantics, interoperability and observability, enabling incremental evolution aligned with emerging standards. It also introduces different architectural patterns — centralized, federated and decentralized — to accommodate varying governance and operational needs. With this approach, IDSA aims to provide a more practical and flexible reference, keeping RAM 4 as a stable foundation while paving the way for the implementation of trustworthy and interoperable data spaces.
