<!--StartFragment--><p class="MsoNormal"><br class=""></p><p class="MsoNormal">Hi David, </p><p class="MsoNormal">I have read your comments to my brief paper and I am,
frankly, disappointed. I was hoping that
you may have abandoned your efforts to make recursion a fundamental
underpinning to the OAIS conceptual model because I don’t think this helps
understanding of the model nor do I think it fits with how most Archives see
what they do,. Therefore I also don’t
think it is beneficial to auditors and will not be a basic framework that can
underlie their thinking. I believe frameworks that Archives find productive
will also be the frameworks that auditors will find useful. Good archival practice must be practical and
not based primarily on an abstraction that has not been proven to be useful. We’ve defined RepInfo to be a recursive
concept because this fits the reality of RepInfo. I submit that most archives do not see what
they do as being based on a recursive
concept. It is not enough to say that one can implement a recursive framework. It must be practical to populate and use, in my opinion. I suspect
you are, at this point, in wide disagreement but please read to the end where I
think I highlight the basis for our disconnect.<o:p class=""></o:p></p><p class="MsoNormal"><o:p class=""> </o:p>Our extensive public and private discussions, together with
your response to my brief paper, is consistent with your continuing effort to
incorporate more recursion into OAIS as a basic conceptual framework. The
strident tone of a number of your comments, such as your opening comment that
my paper “suffers from a number of fundamental misunderstandings and fatal
flaws” seems intended to dismiss discussion of the issues I’ve raised. Maybe it is just that you think your views,
and intent, are so clearly correct that anyone should see and agree. In good
conscience, I can not.</p><p class="MsoNormal">The one factual error in my paper, which I noted in my
response to Mark, is the statement that PDI is no longer applicable to
non-digital Content Information. This sentence should be considered removed,
but this has no impact on the points I’m making. The simple truth, by definition, is that PDI
is now only applicable to the CDO in the conceptual model and this is a very
major change to the conceptual model. This is not saying anything about 16363
or what any given archive actually does.
You say that the note following the PDI definition in the revised OAIS
RM is meant to clarify the definition. It does no such thing. As I said in my paper, the note clearly says
that the general concepts of provenance, fixity, etc. are applicable to the
RepInfo and other information. This is
properly formatted in the note, using lower case, because the note can’t
contradict the PDI definition by using upper case. Surely you see this.</p><p class="MsoNormal">You also say that the previous applicability of PDI was
clearly being misunderstood by archives, so this is a clarification. I have to
wonder how many archives actually were confused by PDI applicability, but I do
know that some key members of this working group misunderstood it. This is what caused the PDI to be restricted
to the CDO in the revision. However once actual applicability was understood by
the group, the proper response, adhering to the guidelines for updates which
you attached at the end of your comments, would have been to make the
clarification and not to continue with the major concept revision. This
clarification could have been accomplished with a sentence of two. While there
was the misunderstanding within the group about PDI applicability, one could
consider the major revision to also be a clarification, but NOT once the
misunderstanding was erased. As I noted
in my paper, the result is a very weakened conceptual model as PDI is now only
associated with the CDO. This is so
obvious that it makes one wonder why the major concept revision has been
retained, especially given the difficulties it has raised (e.g., the note, upper
and lower case).</p><p class="MsoNormal">My view is that this major revision is still in the OAIS model
primarily because you still want to reach a recursive basis for thinking about
the conceptual model. By making the PDI only applicable to the CDO, this is a
step in this direction as I explain below. My view is reinforced by your
interjecting, into my brief but standard view of the OAIS functional model, the
view that the OAIS can also be the Producer, by definition. However the only place this is actually
addressed in the text is when the OAIS has Content Information that needs
updating and thus it submits the updated Content Information to the Ingest
Function so it can get back to Archival Storage. Perhaps you’ve forgotten the extensive email
(private communication) I sent you on these points. This is the standard view that anyone reading
the whole document, and not just looking at a few definitions, comes to. A standard view that readers come to, and
that thus facilitates understandable unambiguous communication, is the basis
for the development and maintenance of the OAIS RM. Instead you have argued,
many times in the past, for treating the Content Information as ‘any’
information that the archive wants to ‘preserve’ (not defined). If adopted, as
you’ve previously argued, you could then treat any information, such as
RepInfo, PDI, etc. as Content Information and its CDO would get PDI. Thus there would be no need to have PDI
directly associated with RepInfo because the RepInfo can be viewed as Content
Information and thus get its PDI this way. This has been your recursive view. You should see that this would be a disaster
for clear unambiguous communication. I believe you have become so enamored with
this recursive view that you have lost sight of the clear communication
objective for the conceptual model. (Again, this says nothing about 16363 or
how a given archive implements its functionality.)<o:p class=""></o:p></p><p class="MsoNormal"><o:p class=""> </o:p>As further evidence, I note that you have interjected, in
two places within my paper, bullets describing general things the archive needs
to do to preserve (your term) some information and then you conclude that these
are, by analogy, associating PDI (actually pdi unless you take any/every
digital object as being a CDO). Of course I don’t object to anyone thinking
this way, and seeing some of the relationships, but it is not anywhere close to
the current conceptual model as anyone would understand it. It is also not
something that I think could be developed into a clear communication model and
it suffers from implying that every piece of information gets the same level of
attention within the archive. I think
one would have to try to develop such a model from the beginning to see if it
was useful. I believe trying to retrofit
this type of thing into the OAIS RM would destroy its utility.</p><p class="MsoNormal"><o:p class=""></o:p></p><p class="MsoNormal"><o:p class=""> </o:p>I’m sure that we’ve been having such disconnect because you
have this broad recursive view that you feel can be used to help auditors focus
on what is needed – a kind of short hand concept way of looking at things. I’m focused on the function of the OAIS RM
for clear, unambiguous, communication and thus I stand by my paper as written,
apart from that one erroneous sentence.
It seems very clear to me that one can’t retrofit your recursive view
into OAIS without destroying its primary function – clear communication. I don’t think any of us want to destroy that,
and thus I hope you rethink your approach. </p><div class=""><br class=""></div><div class="">Cheers-</div><div class="">Don</div><p class="MsoNormal"><o:p class=""></o:p></p>
