Hi Mike,

A couple comments below:

> 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 professional article <http://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1003422> that says “the brain represents a model of its environment and offers predictions about the world.”

 Not to get off on a tangent, but I would have used ‘incorporates’ instead of ‘represents’.  Some argue that  not all knowledge is stored in the ‘brain’. Not my field.

> 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.  

Yes, that is certainly a ‘take away’ point.
> 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?

So my argument is that the experience is personal, but the human perceptible signals that are used to elicit the experience are a category of information that needs to be preserved.  An Archive needs to be able to generate those signals, or ensure that they can be generated.

> Anyhow… very thought-provoking.  Thanks, Don.  Hope I didn’t generate “spoilers” for those that haven’t read it yet.

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.
