Abstract

Inter-organizational data sharing holds significant potential for the industrial sector. It can enable process improvements and novel services and products that drive economic growth and sustainability. In this context, data itself becomes a product that can be shared on data marketplaces. However, the success of data marketplaces in the industrial sector has been poor. One reason is centralized marketplace architectures that limit the sovereignty of data providers and rely on the trustworthiness and neutrality of the marketplace operator. Federated architectures address this problem by giving autonomy and transparency to marketplace participants. In this paper, we report on the results of a two-year design science research project dealing with the conceptualization and implementation of a federated data marketplace in the industrial domain. Based on five design objectives we develop a conceptual architecture of a federated data marketplace, which we evaluate using a prototypical implementation.
