Do you have a definition for "value"? I only ask because
you're the sort of person who might. I regularly recall your
(ISO?) definition for data; I have found that very useful.
My personal definition for "value" is something like a
member of a set, specifically a member of a domain.
I'm less happy with that as time goes by. There's an
interesting mathematical definition for "value" that gave
me a bit of a surprise when I first saw it:
"The quantity which a function f takes upon
application to a given quantity."
http://mathworld.wolfram.com/Value.html
In other words, value is something that is just a
member of the range of a function. Still seems
odd.
Do you have a definition for "information"?
Here's a good definition of "information":
"a formal criminal charge made without a grand jury indictment by a prosecutor in a document."
OK maybe that's not so good for our purposes.
