Subject: Reuters Requirements for DRM
At Simon Blackwell's request, I am forwarding FYI Reuters response to MPEG-21's call for requirements for their Rights Data Dictionary and Rights Expression Language. A key point to note is that the response describes a number of features to be included in MPEG's rights expression language that overlap with many of the "differences" I recently heard Simon list between XACML and DRM. These include: fine granularity the use of rights expressions as policies to drive all manner of enforcement implementations (e.g., file system access, database access, services such as CORBA access, etc) dynamically changing rights (not limited to static objects) predicating rights of access on complex contextual information There are many others. It would be useful to get people's thoughts on just how close the XACML and MPEG-21 activities are likely to become.
