[Moims-dai] Reminder of Skype call tomorrow (replaces the Webex call)

Hi Eld


Hope everything goes well at the hospital.

We had a short Skype call but agreed the discussion on inner-outer would
have to wait until next week.


John is going to produce another version of his restructuring of section 6
before the end of the week, in particular updating the last section, which
covers the inner-outer OAIS.

I am afraid that I cannot attend today, as I have a hospital appointment
with my son.

But next Tuesday, I will be able to, along with Michelle Lindlar, Nancy
McGovern from MIT and Bertrand Caron from the French national Library. 


I acknowledge the work you have done to try and rephrase things, but I think
that the rewrite of the OO-IO part is missing the points - I do not mind the
new introduction to the section 6 (although I have so far only have had time
to skim it), - but I am not in favour of the rewrite of the OO-IO part
(which also seems to be based on the version before the rewrite from the
subgroup which is this: http://review.oais.info/attachment.cgi?id=42 and
which was the version accepted before Mark Conrad's strong objections).


My view on this is that we should go back to the previously accepted version
http://review.oais.info/attachment.cgi?id=42 adjusted to Mark Conrad's
comments from the 7th of September in the following way:

*	The phrase about "Preservation Objectives that are not concerned
with functional interpretation of the bits" is rephrased and referring to
the Designated Community instead.

With the new introduction it should be clear that this is distribution, -
and therefore for readers with knowledge of complexities in distribution.

The comments about OO-IO "being confusing at best" does not hold with the
feedback from various presentations in the community. I have just returned
from the iPRES conference on digital preservation, where I had the best long
paper award for a paper that also builds on the OO-IO model. My presentation
of the paper included the OO-IO model including recursive parts (and
audience included NARA representatives). I only had very positive response,
and no response indicating that it was confusing with the OO-IO model. From
what I heard from other participants in the meetings that it seemed
potential useful to them as well. All the above mentioned persons can report
of the usefulness of the OO-IO terminology, - and if you think it is
necessary, I am sure I can find more known digital preservation
personalities that would like to participate in the next meeting and support
this statement.


Best regards, Eld

Sorry for this late contribution.  
It seemed to some of us that Section 6 wasn't quite on the right track.  I
took a crack at reorganizing a bit and hopefully simplifying it.

I think it remains closer to the starting text from OAIS 2012, but also adds
in some of the new concepts.

I've also eliminated some of more detailed, recursive OO-IO examples that I
thought might be causing some of the disagreement.


I don't know if this will help, but I'm offering it as possibility.  We can
discuss it on the telecon later today if others think it useful.


Peace and joy,

This is the last open issue we need to resolve to finalise the draft.


1.	http://review.oais.info/show_bug.cgi?id=135 (Outer OAIS - Inner OAIS
model for Distributed digital preservation) was re-opened for further

As discussed 2 weeks ago at the MOIMS-DAI Skype call, I took the ideas I had
previously circulated and have restructured the text in section 6 in order
to clarify the relationship between the different arrangements of
organisations described in this section, which was one of the main talking
points in previous calls. See http://review.oais.info/attachment.cgi?id=50 

You will see that it is mostly a rearrangement of text existing in the
draft, with some additional "glue" to try to show the relationship between
the different options.

I moved the text from the last subsection into an earlier subsection and
replaced it with a brief discussion about Technical Issues about
interoperability. It may be useful to expand that a little in order to link
to the document Steve is preparing.

              Mark sent his comments on this proposed restructuring of
section 6 on 25th Sept.


There was also an action on me to suggest a clarification about
Representation Information, which I attach, and which I hope we can discuss.
