Abstract: In a cross-organizational context, software services are provided and consumed by different organizations. Ensuring that the non-functional requirements of all the involved organizations are satisfied is hard to achieve in such a distributed and heterogeneous environment: the implementation of features, for example security, is scattered across the services of multiple organizations.

In this paper we present a coordination architecture for flexible and policy-driven composition of cross-organizational features in distributed service systems. The underlying approach of this architecture is to specify the features and their composition at a higher level that abstracts the internal implementation mechanisms of the organizations involved. By means of feature composition policies the organizations specify at a fine-grained level which features are required and when they have to apply. Driven by these policies our coordination middleware dynamically integrates the appropriate features throughout the cross-organizational service composition in a consistent and efficient way. We have validated our architecture in a proof of concept showing limited performance overhead.
