well traditionally meta meant something "bigger or more than". so meta
information is used to add meaning to something else. if the so-called
meta information is included in the subject, then it's not meta
information. that's just the definition.
the paper referenced by len goes back to the mathematical basis of this.
perhaps a simple example would be to consider the relationship of a
group to a real number. groups are meta information about numbers. they
describe a "complete" system of operations on real numbers. but the real
numbers themselves have nothing about them (when viewed as numbers) that
says anything about the group. ie the number 1.25 says nothing about the
significance of 1.25 * 2.5. that's the meta information provided by
group theory.
so from a data perspective (and perhaps from a document perspective too)
i think there is a lot to be gained by differentiating data from a view
of the data.
but that can take us back to the data/document divide ;)
