I see your point, … In my perspective, the statement “Dan Brickley is the
creator of this particular data item” is metadata (it encodes a
proposition about data). In contrast, “Dan Brickley works for Google” is
not (it does not encode a proposition about data).

This does not mean that metadata and non-metadata cannot be used together,
in which case the conjunction of both statements may be relevant to
characterize a data item as you suggest. Thus the statement “The creator
of this data item is employed by Google” is metadata.

To me, considering “Dan Brickley works for Google” as metadata because it
may be used together with metadata is what causes the confusion. I hope we
can find some way to clarify this. I don’t feel the disclaimer you
suggested will do the job.
