A data space use case is a specific setting in which two or more participants use a data space to create business, societal or environmental value from data sharing. The value of a data space for all parties, including the governance authority, is created through use cases. Successful use cases are vital for the long-term viability of a data space. Use of data space technology for the implementation of use cases is particularly beneficial when numerous participants engage in data sharing (making point-to-point integrations challenging and emphasising the issues of data sovereignty and trust) or when the same data can be utilised across multiple use cases.
