Hi Helen,
I think I'm in full agreement. See some brief responses below.

This is certainly my view.

Agreed.

Yes, there are no guarantees, only 'best practices' that we hope can
be checked to some level to establish a degree of trust.

Yes, not all 'requirements' are necessarily equal in terms of
establishing trustworthiness. I think some of the existing TRAC
requirements are 'not essential'. At NSSDC we're in the process of
trying to document how we do, or will, meet most (but not all) of the
TRAC requirements. We've extracted the ones we think are most
important for this analysis. I see this as an evolutionary process
since we're learning as we go, both at NSSDC and in the development
of this document. Perhaps when we get to audit scoring, or even
before, some requirements will become less significant or even 'nice
to meet but not mandatory'. That said, our experience is that it is
VERY easy to have information corrupted by gaps in detailed processes
and that tracking of actions within the archive/repository is very
important. Tracking this at the right level of detail is tricky, and
then what provenance should be saved and what can be deleted? We're
trying to address this as we re-engineer our processes. And, we've
been in this business for 40 years!
