Data Spaces: A New Realm to be Explored and Understood

Updated: Jul 3

Data spaces are infrastructures that will allow data transactions to take place between different parts of a data ecosystem based on the governance framework of the data space.

Therefore, data spaces are ideal infrastructures for situations where data is spread across multiple owners and trust needs to be established in the exchange of data, with data sovereignty and control being vital.


A data space can act as a service for an individual organisation to help find and access data sources, control the sharing of those data sources, and serve to manage those data sources.


Data space limits

One of the points discussed in the plenary session from Madrid was to establish the limits of the so-called data spaces. Based on the idea of the sovereignty of these spaces, the space is considered a unit with its own entity; each of them has its own identity, autonomy and rules, system of governance, management and maintenance. This is a major challenge that DS2 faces when looking for solutions that allow the exchange of information in a secure way.


The main characteristics that a data space must fulfil are as follows:

  • Assisting in finding data sources.

  • Assisting in accessing those data sources.

  • Controlling ownership of and access to data.


There are three levels or domains of application with different objectives:

  • Social level: create an environment of trust.

  • Technological level: develop solutions that facilitate secure exchange.

  • Business level: reduce the costs of accessing information.


Approach to the solution

The plenary meeting focused on the technological level where, in addition to Minsait, actively participated IBM, Software AG, ICE, VTT and the University of Southampton, amongst others.

The concept of the DS2 Toolkit was introduced, a set of tools that would cover the main requirements for access and interoperability of existing data spaces. It was concluded that DS2 will not create a new global data space, but will provide the necessary tools that are lacking in the existing ones.


These tools aim to support the basic characteristics of the data space, with the objective of:

  • Building trust.

  • Publishing and searching for a supply of data.

  • Managing access to data.

  • Managing the sharing of data.

  • Controlling the use of data.


Minsait's participation with Onesait Platform

Within this innovation project, Minsait will work with the data part, focusing mainly on data orchestration, contract, monetisation, trust and restriction, as well as its lineage throughout the entire life cycle.


For this purpose, Onesait Platform will be used as the platform for ingesting, storing and managing the data. These developments will be carried out in accordance with IDS (International Data Spaces) and Gaia-X specifications. One of the main areas where Minsait will work will be to develop the module for compliance with the policies and contracts established for data exchange, as well as a data transformation module to facilitate data exchange between providers and consumers.
