Sarah, Greg, Heather,

I have a follow-up question to this discussion of TPM's.

If the file/work in question has has identifiers/fingerprinting attached to
it which help identify the right holder, author, CC licensor, ...,  but
does not restrict access to the file is that considered a TPM? I assume the
identifications, whatever, could be construed as protecting the rights
associated with the file but not the file itself. But, does this mean that
licensee does not have the right under the 'TPM' clause to remove these
identifiers if they don't restrict access? Should a distinction be made
between technical measures protecting rights and those protecting access to

Thanks for the clarification,

Nicholas Bentley
