Digital Rights Management (DRM) is the basis of Sun's technology DReaM that has been contributed to the Open Media Commons initiative. Project DReaM is an initiative to develop an open DRM solution and reference architecture for multiple domains (media, documents, enterprise, personal, etc.). Four white papers have recently been released detailing the project's goal, licensing and specification, among other aspects.

Support for Fair Use with Project DReaM

A brief overview of fair use and some specific assumptions on its applicability to DReaM will be the groundwork for building a DRM architecture supporting fair use. This white paper will cover the conditions of anonymous fair use, discuss tracking and auditing methods to uncover the anonymity under conditions of misappropriation and detail the DReaM architecture and the processes for anonymous fair use and the auditing of the process.

DReaM-MMI Profile for Creative Commons Licenses

A key piece of DReaM is the DReaM-MMI protocol, which defines all interaction between the client and a DReaM server. The main purpose of this profile is to document how MMI is used by clients to access Creative Commons licensed content, and how a DReaM server interprets these licenses and responds to client requests. This profile describes Creative Commons licenses in some detail, defines the DReaM model in more depth, provides specific terms that the client provides in requests and the responses that the server uses. This piece also details the security model and license management.

Learn more about the updated DReaM-MMI-Simple-Specification (v1.0), which is now available, in the following documentation:

DReaM CAS (v1.0)

This document provides the client specification for a conditional access system (CAS) that will be referred to as DReaM-CAS. The specification covers content protection and key management. Media transport, content cryptographic algorithm and key management algorithm are fully defined.

DReaM MMI (v1.0)

This document provides the protocol specification for a rights (license) management system that will be referred to as DReaM-MMI. The specification covers rights request and responses. The protocol for requesting and responding user rights for content is fully defined.

To access these last two documents, visit the Open Media Commons Website. [...read more...]
