Tokyo Press Release




DMP publishes version 2.1 of its specification with

Open Source Software

Tokyo, Japan, 2 February 2007 – The international Digital Media Project (DMP) concluded its thirteenth General Assembly (GA13) today, approving the new version of the Interoperable DRM Platform (IDP-2.1). The specification adds several new important technologies, e.g. a machine readable “rights ontology” that will allow devices to understand the relationships between roles in a value chain (creator, performer, producer etc.), rights and content, and the new Approved Document #7 “(AD #7) “Reference Software”.

Called Chillout®, the DMP Reference Software is a Java implementation of IDP-2.1, released as Open Source Software under the Mozilla Public Licence V.1.1. Chillout® is constantly improved by a growing community that currently counts members from China, Germany, Italy, Japan, Korea, Spain and other countries. The Subversion server holding the code base is hosted by the Chinese Academy of Science in Beijing.

With the high degree of maturity achieved by the specification and the reference software the DMP has decided to begin to set up the governance infrastructure required for the practical use of the specification. Therefore GA13 has issued a Call for Participation in the selection of the DMP Content Registration Authority. The main purpose of the Authority is to appoint and oversee the operation of Content Registration Agencies.

The next DMP General Assembly (GA14) will be held in April 2007 in San José, CA. The main goals for that meeting will be to add some missing technologies to IDP-2.1, to continue improving Chillout®, to approve AD #8 “End-to-End Conformance” and AD #9 “Recommended Action: Mapping of TRUs to the Digital Space” and to appoint the DMP Content Registration Authority.

The Digital Media Project was chartered as a non-profit organisation on 1 December 2003 in Geneva, Switzerland. Its mission is to introduce an integrated body of technical standards promoting the successful development, deployment, and use of digital media, while safeguarding the rights of creators and rights holders to exploit their works, the wishes of end users to enjoy fully the benefits of digital media, and the interests of value-chain players providing products and services.

The DMP’s Board of Directors is: Marina Bosi (MPEG LA, LLC, USA), Leonardo Chiariglione (, Italy), Domenico Di Martino (Telecom Italia, Italy), Nigel Earnshaw (BBC, UK), Marc Gauvin (Sociedad Digital de Autores y Editores, Spain), Jinwoo Hong (Electronics and Telecommunications Research Institute, Korea) and Tiejun Huang (Peking University, China).
