I normally accord to the definitions:
information = datum + meaning
These are useful, succinct and accord nicely with [ISO 2382-1:1984]:
“Data: A representation of facts, concepts, or instructions in a
normalized manner suitable for communication, interpretation, or
processing by humans or by automatic means”, while giving something a
bit more formalized in terms of data theory.
In terms of defining value both the output of a function or the
element of a set seem fine, but then defining a value as being some
datum = value + description
