Hi David,
Great post, I very much agree with what you are saying. It echoes some of what I said in a comment here e.g.:
"The problem is the cost of preventing change. Some changes are presumed to be more expensive than others to prevent. The trouble is that at the moment we don’t have good economic models to predict the cost of employing different strategies to prevent change (while also enabling access) and therefore we cannot compare the different strategies either."
In retrospect, I should have referenced your post in the comment.
Your work on the cost of long term storage is a superb example of the kind of cost modelling I believe we need for other areas in the digital preservation space.
Over here I speculated that employing an emulation strategy will probably be a cheaper option for maintaining access long term in many cases. But I was careful not to say it definitely will as we just don't have enough evidence yet to be able to make an informed decision about it.
So while I might ask for models similar to yours for use in predicting the cost of different strategies, I fear that it will be some time before we are able to produce them.
