Abstract
Data-driven economies on the World Wide Web are based on coordination mechanisms for exhange and AI-based processing data assets provided by independent actors. Architectures for data-driven economies currently focus on the exchange of data assets and leave processing of data assets to background mechanisms. Without binding obligations, data sharing situations favor "no data sharing" as dominant strategy between agents. We present a broker framework that supports contract-based sharing, trading and processing of data assets between actors under 'lack-of-trust' conditions. Electronic contracts guarantee ownership and control of data assets, execution of defined data analytical tasks based on AI models and sharing of results according to contractual promises. A technical architecture (TUCANA) is presented that realizes a federated data economic ecosystem including the broker framework. We present an application based on an implementation of TUCANA.
