Hi Mike,

Thanks for  your comments.  A quick reading seems to me you certainly got my thrust in the first Discussion (section 2).  I’m heading to Canada in the morning so will have to give you a more thorough response in a day or two.

> 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.”
> 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.
