As data is becoming an increasingly valuable asset for organizations, pressure to improve its governance is increasing. Prior research provides a thorough view on data governance within a single organization. Although data sharing with partner organisations in data platforms provides a means to add data’s value, empirical studies addressing data governance in shared data platforms are still few. We propose a literature based preliminary framework for platform data governance with five domains: original data quality; ownership and access; stewardship; platform data quality and value of data usage. We report experiences from a European shipbuilding network, which is seeking ways to share data collected during ship’s operations. While the device manufacturers already process sensor data within their device-specific platforms, they are knowledgeable about potential benefits of sharing their data with others in the network. Based on interviews within the shipyard network, we report views along the five platform data governance domains.
