In this paper, we present a preliminary design of a framework for coordinating and enforcing usage control policies across different collaborating organisations. We named our framework xDUCON. The main goal of xDUCON is the specification of usage control policies that concisely capture conditions, authorisations, and obligations on both providers and consumers of resources. The novelty of xDUCON is its enforcement design that is based on the Shared Data Space (SDS) abstraction. The SDS allows the coordination of the decision and enforcement points abstracting from the details of the actual deployment of the framework. Moreover, the SDS abstraction caters for the necessary synchronisation facilities necessary to realise a concrete implementation of control usage framework such as support for entity mutability and control over long-lived sessions to evaluate the access rights of a subject while the access is being executed.
