All written down on a bit of paper - same values discussed, but
different data. Agree or disagree?
I agree. Yes, same values but different data
I ask this because if we can distinguish data and values, we must then
determine /how/ they are different. You state it is by "encoding" but
the two lines above are encoded in the same manner as far as I am
concerned, so that cannot be the difference between the two concepts.
That is unless your "Encodings" equates to my notion of "Facts", and
we are thus agreeing loudly, using different definitions of those
terms.
They are the same values and they are encoded in the same manner.
However they are distinct appearances, hence distinct data.
Ok, so we're agreed at least there. Same values with the same
encoding. Yet the first datum is different to the second. The logic
below therefore follows:
1) The two items of data discussed have the same values and same
encoding.
Yes.
Hey Brian. That's good - at least there is consensus there.
2) The two items of data can obviously be distinguished (we are agreed
they are not the same data).
No. They are the same data.
Ok, that I personally find a strange use of the term. You seem to be
saying that:
P(a, b)
Q(a, b)
is the same data? To me that looks like the first line is a different
datum to the second, even though they share the same values.
Definitely not in your opinion?
3) Therefore a datum must possess some attribute outside of its values
and encoding.
Yes, but not what you think: A fact is supposed to be true.
Each appearance of a value in a proposition that is supposed to be true is
data, but each appearance in the same proposition is the same data.
But isn't it also true that at least some combinations of values, such as those
combinations of values that appear in a tuple, may also be data?
What complete and utter nonsense! Why, oh why, Jim, do you inflict this
on the rest of us?

Y'know, I have no idea. I think it must be wishful thinking.
You mentioned the idea of creating a new online resource. Are you still pursuing that?
