You think it is an object model because you want to look at it as if
it were an object model for these file objects.

There will be a set of interfaces that describe the various
interactions of the componets in various scensarios. You are free to
extend them to suit your own needs, sample implementations will be
provided as part of the Baboon libraries and you can extend those,
override them or reuse them as you see fit.
Ala, this is hardly connected to files in the file manager :-).

I do not see the connection between a document model and the file
manager here. I am sorry, but I really cant figure out what role does
the file manager play in my spreadsheet nor the word processor.
I am starting to believe that you and I are thinking of very different
