Harmonization Profiles for Trusted Data Sharing Between Data Spaces: Striking the Balance between Functionality and Complexity
conference paper
The ambition of the EU Data Strategy can be summarized as a ‘federation of interoperable data spaces’. Currently, a multitude of architectures, frameworks and protocols is used by various data spaces. The Data Sharing Coalition has provided an architecture framework for interoperability between data spaces, making use of a harmonization domain and data space proxies as key architecture concepts. Complete interoperability between a wide variety of data spaces presents a challenge for the harmonization domain. To enable interoperability between a variety of data spaces, a set of harmonization profiles are required in the harmonization domain to provide the necessary functionalities. However, implementing each harmonization profile comes with additional complexity. Therefore, it is desirable to identify a minimal set of harmonization profiles to provide interoperability between an adequate variety of data spaces. This paper addresses the identification of harmonization profiles, presents a framework for structuring harmonization profiles and explores the impact of key trust aspects (policy management and trust ecosystem) on harmonization profiles.
