Design rules for interoperable domains: controlling content dilution and content sharing

In this paper we argue that improved interoperability between DRM systems is likely to benefit to all the actors in the content value chain. Moreover, we describe a domain-based approach to DRM interoperability. We discuss in some detail configuration aspects of such interoperable domains, and how they affect certain social aspects such as marriage and divorce. We conclude that interoperable domains offer a much needed flexibility, allowing users to more easily move between vertical silos and offering content owners a more flexible environment for selling content.
