Subject: Re: [office] DRM issues

I agree completely.  This is a FUD-fighting issue, and I don't think we need to change anything in the spec.  However, a statement from this TC that explains how ODF and DRM would be expected to interoperate would probably be helpful to the folks fighting the political battles.  With luck, it won't be a huge effort to produce such a statement.  -- Nathaniel

Re: [office] DRM issues


I think we are in full agreement that specifying a DRM mechanism itself is
ouside the scope of the TC, because the use of DRM is neither specific nor
restricted to office documents.

I also think that a check whether OpenDocument works with a variety of
possible DRM mechanisms might be useful, but is also outside the scope of the
TC. To the best of my knowledge, there are no open standards for DRM right
now. All DRM mechanisms that exist are vendor specific. While an
interoperability check for an open DRM standards might be within the scope of
the TC, I think interoperability checks with vendor specific DRM systems
should be performed by the vendors of that systems, or by vendors that want
to use a specifc DRM system together with OpenDocument in an application.

The results of such checks of course might be discussed by the TC, and it
probably would be admissable to have them somewhere at the TC's web pages.

Best regards
