Various embodiments provide a mapping layer to translate DRM system requirements from one DRM system, such as a source system, to another DRM system, such as a target system. In at least some embodiments, DRM system requirement translation is performed using a signed data structure that maps DRM system requirements from one DRM system to one or more other DRM systems. By mapping DRM system requirements from one system to another, licenses associated with DRM-protected content and associated content can be safely transferred between systems.
