We present the Obligation Specification Language (OSL), a policy language for distributed usage control. OSL supports the formalization of a wide range of usage control requirements. We also present translations between OSL and two rights expression languages (RELs) from the DRM area. These translations make it possible to use DRM mechanisms to enforce OSL policies. Furthermore, the translations enhance the interoperability of DRM mechanisms and allow us to apply OSL-specific monitoring and analysis tools to the RELs.
