I have a different take:

A value has no value except that which is assigned to it under an interpretation: a value is not the output of just /any/ function, but rather /the/ function that maps language terms to what those terms mean.

Information is just one or more values.

A datum is simply a formatted value that cannot be broken down into a collection of component values that means the same thing.

Data is just formatted information. Received on Thu Jul 03 2008 - 22:48:30 CEST
