The introduction of Sea Traffic Management services relies on infrastructures that enable trustworthy information sharing and service provisioning/consumption processes. For this purpose, a federated and regulated approach to information sharing and service distribution is proposed. Such an approach would position the governance of different services in the continuum of hierarchical (i.e.command and control) to market-driven approaches. In this paper the maritime infrastructure framework is presented and applied to Sea Traffic Management. The full potential and large-scale implementation would come when the same framework is applied in different areas of application that rely on information sharing, service interaction, and (digitized) actor collaboration.
