IDS RAM 5 will connect governance and architecture to drive interoperable and trustworthy 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, which evolve independently and align with emerging standards such as the Dataspace Protocol (DSP) and the Decentralized Claims Protocol (DCP). It also introduces different architectural patterns — centralized, federated and decentralized — and fits coherently within the IDSA documentation ecosystem, linking the Manifesto and the Rulebook with implementable technical architectures. While RAM 4 remains a stable foundation, RAM 5 defines the evolutionary path toward interoperable and trustworthy data spaces.

If you want to learn more about the evolution of the IDS RAM and its impact on data spaces, we invite you to join the Data Spaces Symposium 2026, a key industry event that will also feature leading voices from the BAIDATA ecosystem.
