[IETF-IDRM] RE: [IDRM] Disband or recharter IDRM?

Thu, 12 Dec 2002 08:54:18 -0500

I believe the best thing the group could do is:
1.  Define the file format (a.k.a. package format) for a DRM protected
file.  Currently each DRM products has it's own proprietary format.
2.  Recommend a rights expression language (ORDL or XrML).
3.  Recommend a key flow.

The group should stay away any ideological issues.  DRM will be used in a
variety of situations, not just for music or video.  Unless we want a
single company to set the direction and provide all the tools we need to
set standards.

I also think the group should stay away from the technology for developing
the "client."  Each individual company should make its own protected
client, and the content owner can restrict which client can use the content
with certificates.

Yes, but ..

The 'deliverables' are not clear ... for example:

"The IDRM Research Group will begin its work by surveying the area of
Digital Rights Management (DRM), and develop a coherent taxonomy of
problems related to DRM with their inter- relationships."

I'm not sure how I would use this result.

Picking a smaller clearer deliverable would hopefully get more interest and
involvement.
