[Moims-dai] OAIS SC 235: OAIS Preservation Issues

Hi Don,


I certainly agree that your input is well-crafted and thought-provoking.

I think it could be used as a basis for one or more paper submissions to
some of our digital preservation conferences.


It also provokes questions of what needs to be updated in the OAIS.  I'll
have to give that more thought.  For me, some parts seem to
metaphysical/philosophical to be practically included in OAIS.  Other parts
I see as almost requiring that we make some updates to OAIS.


One place I believe that we need to make updates is in discussions of PDI
content being Information Objects.  Based on your interpretation of directly
viewable information/documents not being Information Objects (which
interpretation I agree with), then we can't say that, for example,
Provenance Information is an Information Object.  It could be, but is not
required to be an Information Object.  It will only be an Information Object
if it requires and has Representation Information associated with it.  This
is all closely related to Representation Information Networks.  At some
point the Network needs to end.


I think you've expressed well the experience and/or understand bit much
better than we've done so far.  We've discussed that before and for me that
is getting addressed through the introduction of the Preservation Objectives
and Transformational Information Properties which for me allows for
"understanding" that allows experiences - e.g. understanding the b/w photo
means that the Designated Community must be able to view it.

This is also closely related to our understand and/or use discussions that
we added in the previous update.  I think we've found that to be confusing
to people and leads us down all kinds of rabbit holes when start talking
about systems understanding the information.  Again I expected David's
introduction of Preservation Objectives  and TIPs to help in that regard


I think the Preservation Objectives and TIPs also handle much of the
Information presentation concerns.  I agree that Information presentation is
an important concept and we probably should discuss it more in OAIS.
However I'm not sure that I agree that the current OAIS doesn't allow for
experiential information.   Certainly we should tweak the definitions if
that is how others see it.


Certainly we'll want to discuss this more.


Peace and joy,

Don, I have to say that was a well-crafted and thought-provoking writeup,
especially the first section.  I think I got both knowledge and an
experience (pleasurable) out of reading that.  


All:  I fully support Don's suggestion to add experience preservation as a
salient component of the concept of OAIS.  Bear in mind that I'm the new
guy, so that may or may not lend the concept credibility.  


Don, in the process of adding the missing component, you focused on the term
"experience".  I have always held a concept that the brain maintains a
"software model" of the environment.  Once the sensory inputs come in, they
add to that software model and the increasing fidelity of that model can, I
think, be equated to gaining knowledge and experience.  In support of that,
here's a statement from a
22> professional article that says "the brain represents a model of its
environment and offers predictions about the world."


That software model of the environment in the brain may be where knowledge
and experience (while perhaps separate concepts during transport from the
picture on the wall to the brain) may merge back together to be one thing.
that software model of the environment.  So. I don't know if that helps or
hurts your case.  But I think your point is. OAIS needs process/mechanisms
that are guaranteed to handle both traditional knowledge and less-tangible
experiential knowledge...  experience.  


I really like your example of the black-and-white picture on the wall.  One
person may take away only the memory of a black and white image on a wall,
and nothing more.  Another person, seeing the black-and-white image of
soldiers in the trenches in WWI may take away only the knowledge that
soldiers were dirty.  Another may look into that image and be transported to
that environment in WWI, experiencing it as much as the media allows.  Which
is knowledge and which is experience?  May be difficult to draw the line.
And if that photo of soldiers in WWI has Wonder Woman PhotoShopped into it,
that conveys something completely different. fantasy rather than knowledge.
Or can fantasy be knowledge also?  


Anyhow. very thought-provoking.  Thanks, Don.  Hope I didn't generate
"spoilers" for those that haven't read it yet.

After taking a more detailed look at digital preservation concepts than I
did originally as a co-editor of the OAIS RM, I now find I missed an
important aspect of information and its presentation to human senses. There
is also an error in Representation Information modeling as it is not always
an Information Object.  This paper is my attempt to pull this together into
what I hope is understandable and convincing.
