This document lays out the specifications for a componentised DRM system. Requirements for a general DRM system are discussed, and we detail a set of components that address these requirements. This document also details the specific services that should be offered by each component and specifies the communication protocols and contents of these messages.
Each of the components of the DRM system are fully fledged web services, and thus some of these components can be used in areas other than DRM. Furthermore, we envisage existing services, such as Certificate Authorities, easily fitting into our proposed framework
