Data spaces allow participants to share, trade, and collaborate on data assets in a manner that is compliant with the participants’ needs and regulations. These spaces could unleash the enormous potential of data-driven innovation. However, large-scale data sharing is hampered by concerns about trust and the lack of control mechanisms for sharing secure and trusted data. Therefore, standardisation of data space architectures that better support secure and trusted exchanges has received notable attention. The need for structured data spaces has grown, and considering the geopolitical situation, there are significant efforts by the European Commission to stimulate the development of common European Data Spaces.
In addition, the maturity heavily varies per domain. The maturity of a metadata standard within the domain enhances the data space’s maturity. Also, the legal basis used within the domain can be very different from domain to domain.
