Data Spaces: Unlocking the Power of Connected Information

By Samuel Fanoukoe

In today's digital world, data has gradually become an invaluable currency that drives innovation, decision-making, and business success. The exponential growth of data has led to new challenges in managing, organizing, and extracting meaningful insights from vast and diverse datasets. To address these challenges, the concept of a data space has emerged, offering a promising solution to unlock the power of connected information. In this blog post, we will explore the notion of data spaces, their history, some technical overview, real-world applications, and references to some materials for further reading.

Data sovereignty

Before diving deep into data spaces, let us look at the concept of data sovereignty. Data sovereignty allows individuals or organizations to have the right to control and own their data, ensuring compliance with relevant laws and regulations. It involves determining how data is collected, processed, stored, and shared, safeguarding privacy, intellectual property, and regulatory requirements. For more information see Data Sovereignty and Data Space Ecosystems.

What are Data Spaces?

Data spaces represent a hub where data from different sources in different formats can easily be integrated, linked, and made accessible to data consumers for analysis and decision-making purposes. One of data spaces' goals is to enable data sovereignty, allowing data providers to stay in control of their data. Contracts and policies customized for the data consumers enforce data sovereignty.

There are two main ways to look at data spaces: as a centralized hub, where all the data stays in one location for participants to access, or as a decentralized hub, where each participant holds their data but makes it available in the ecosystem. No matter the underlying architecture, we can abstract data spaces to the following characteristics:

  • Data providers provide their data to be used however they choose,
  • Data consumers consume whatever data they find relevant to their cases, based on whatever is available in the data catalog,
  • Brokers provide an enabling environment to conduct Data business. This environment will allow data providers to give an overview of their data assets and how they should use it. Data consumers will also be able to look for data that suits their project needs based on the characteristics of the data asset.

Finally, one last key aspect of data spaces is that they are designed to be technology agnostic for data sharing, allowing for data portability regardless of the platform on which it is hosted or consumed.

Technical Overview of Data Spaces

The following concepts are core to common data space implementations. Therefore, we explain them:

Data Space Connector: A data space connector is a technology that enables seamless integration and exchange of data between different systems, ensuring compatibility, security, and efficient communication. It acts as a bridge, facilitating data collaboration and interoperability. There are different connectors available, examples include the Eclipse Dataspace Components (EDC), Dataspace Connector (DSC), FIWARE TRUE connector (FTC), and more.

Identity Provider: This service plays a crucial role in managing the authentication and authorization of data providers and consumers. It ensures that only authorized users have access to the data and establishes trust among participants in the data exchange process.

Catalog: The catalog service allows for the registration of new offerings and review of existing data assets. Data consumers can choose from the available options, while data providers can add their data assets to the catalog, making them visible and accessible to potential consumers.

Policy Engine: The policy engine service is responsible for managing contracts between participants before exchanging data. It ensures that the agreed-upon policies and terms are enforced during the data exchange process, providing a framework for data governance and compliance.

Identity Management: Identity management involves the administration and control of user identities, access rights, and permissions within the data exchange ecosystem. It ensures that the right individuals or entities have appropriate access to the data while maintaining security and privacy.

Configuration: Configuration refers to the process of setting up and customizing the data space connector and its associated services according to the specific requirements of the participating organizations. It involves defining connection parameters, security settings, and other configurations to enable smooth data exchange.

Contract Management: Contract management involves the establishment, negotiation, and enforcement of contracts between data providers and consumers. It includes defining the terms, conditions, and policies for data exchange, as well as monitoring and ensuring compliance with the agreed-upon contractual obligations.

Data space initiatives

The concept of data spaces has been around since the early 2000s. However, one of the first true implementations came in 2015, when the International Data Space (IDS) initiative was created, a project funded by the German Federal Ministry for Education and Research. Their goal was to create an ecosystem aimed at the design and prototyping of a distributed software architecture for data sovereignty. The IDS Association now has more than 130 members from more than 20 countries. This not-for-profit association created an IDS Reference Architecture Model (IDS RAM) which is a data space software Architecture. The IDS RAM has now become a blueprint for a secure pathway for data exchange.

After the IDS Initiative's launch, The Gaia-X followed suit in 2019 with the goal of data sovereignty in a broader context than IDSA. Gaia-X is a pioneering European initiative trying to establish a trusted and sovereign data infrastructure. It promotes secure data sharing, storage, and processing, driven by transparency principles, interoperability, and data sovereignty. Leveraging technologies like cloud computing and AI, Gaia-X fosters innovation, competitiveness, and digital autonomy while ensuring data privacy and security. With an open and collaborative approach, it aims to become a global model for data infrastructure, enabling sustainable digital growth.

Catena-X is a transformative initiative revolutionizing the automotive industry through seamless data integration. As a consortium of over 60 companies, including major manufacturers and suppliers, Catena-X aims to create a digital ecosystem where data can be securely shared and utilized. By leveraging cutting-edge technologies like blockchain and AI, it enables enhanced transparency, efficiency, and innovation across the automotive value chain. Catena-X's collaborative approach and commitment to data sovereignty pave the way for transformative solutions in supply chain management, manufacturing optimization, and personalized customer experiences. It is poised to shape the future of mobility and accelerate the digital transformation of the automotive industry.

One last worthy mention is the Mobility Data Space (MDS), a platform that aggregates, manages, and shares mobility-related data from different sources. It offers standardized interfaces, protocols, and data formats for easy integration and interoperability between mobility data sources. The MDS promotes data collaboration, allowing stakeholders to access and leverage mobility data for various purposes, such as traffic management, urban planning, and transportation optimization. It ensures the responsible and secure handling of sensitive mobility data by incorporating data governance and privacy mechanisms. The MDS promotes innovation and efficiency in the mobility sector by enabling data-driven decision-making and fostering the development of new mobility services and solutions.

Real-World Applications of Data Spaces

The application of data spaces spread across different sectors like, healthcare, finance, manufacturing, mobility, and many more.

The Data Intelligence Hub by Deutsche Telekom is the first secure marketplace that addresses the challenges companies face in sharing data, such as lack of transparency, security, and trust. It enables companies to exchange data and collaborate within a trusted business ecosystem based on the International Data Spaces principles. The hub serves as a digital connection between companies, providing tools for data analysis, acquisition, exchange, and processing. It empowers industry experts to develop new business models and data-driven products or services, benefiting companies of all sizes, industries, and even universities working on data and algorithm integration for valuable insights.

There are many more use cases that can be found in the IDSA brochure.


Data spaces represent a paradigm shift in the way organizations  in both the private and public sector approach data management and analytics. By providing a unified and connected view of data, data spaces empower organizations to extract insights, make data-driven decisions, and drive innovation across various industries. The ability to integrate, explore, and utilize diverse data sets in a collaborative environment is a game-changer that will shape the future of information management and analytics. As organizations embrace data spaces, they will unlock the true potential of their data assets and gain a competitive advantage in the data-driven economy.
