The architecture of Data Space does not require central data storage capabilities. Instead, it pursues the idea of decentralization of data storage, which means that data physically remains with the respective data owner until it is transferred to a trusted party. This approach requires a comprehensive description of each data source and the value and usability of data for other orgnizations, combined with the ability to integrate domain-specific data vocabularies. In addition, brokers in the ecosystem provide services for real-time data search.
