Navigating through data spaces with the IDS Reference Architecture

At the heart of data spaces lies a fundamental element—the IDS Reference Architecture. Much like the Internet Protocol forms the backbone of the internet, this architectural framework is the cornerstone for all the innovations and functionalities that layer on top.

Consider this analogy: Are you familiar with how the Internet Protocol works? It quietly ensures the seamless flow of information, enabling the internet to function cohesively. Similarly, the IDS Reference Architecture is the silent orchestrator, making sure that data spaces operate seamlessly.

Why is this so crucial? Because, without it, the grand vision of data spaces, a vision we are collaboratively defining and designing, would be nothing more than a mirage. As we step into this year, this architectural cornerstone becomes even more essential, shaping the strong foundation on which our data spaces will flourish.

The role of data space authority

Let’s have a look at another crucial role within these data spaces—the Data Space Authority. Whether embodied in an organization or a contractual framework, this authority plays a vital role in overseeing the entire data space. It manages participants, upholds rules, and maintains policies, ensuring the smooth operation of the data space.

While this concept isn’t entirely novel, recent insights shed a broader light on its significance. The growth of diverse data spaces, each unique yet sharing commonalities, necessitates a more nuanced approach than previous reference architecture models provided. Considerations now extend to different approaches in building data spaces—centralized authority, decentralized networks, or the pursuit of federation among various data spaces.

Reflecting this diversity involves addressing legal, organizational, semantic, and technical perspectives. The IDS Reference Architecture Model 5 is our response to these challenges, slated for release before the summer of 2024. Although not the final version, this draft aims to offer insights and guidance on addressing the challenges presented.

RAM 5: A modular approach for comprehensive guidance

With a renewed focus on the data space participant, IDSA-RAM 5 will adopt a more modular structure. The goal is to guide users through the decision-making process of building data spaces, considering the unique requirements and perspectives of each stakeholder.

This new model will present three distinct perspectives for data space authorities: joining an existing data space as a participant, providing value-adding services and ecosystem services, or collaborating with a group to build a data space. The document will guide stakeholders through critical decisions, from establishing business rationale and functional requirements to structuring information models, implementing processes, and determining the systems to be built.

Unlike its linear predecessors, Reference Architecture Model 5 will not be a page-by-page journey. Instead, it will serve as a comprehensive tool which aims to provide clarity on individual viewpoints. The document will assist in understanding the common ground, implementation barriers, and design choices, fostering a collaborative and informed approach to building data spaces.

As we embark on this transformative endeavor, we invite IDSA members to join us in crafting Reference Architecture Model 5. Your insights, expertise, and contributions will play a crucial role in shaping the future of data spaces.
