Put this way, it sounds to me like what the DCMI Abstract Model
calls a Description (see below).

I see the argument but still see a problem with the notion of
a record being "about" something.  Looking at a bibliographic
record through traditional bibliographic glasses, one does see
a set of data elements "about" a book.  Looking at that same
record through RDF glasses, however, one may see statements
"about" several different things -- the book, its author,
the publisher, etc.

The DCMI Abstract Model tried to express this point by
distinguishing between a Description (a set of statements
about just one resource -- e.g., the book OR the author OR
the publisher) and a Description Set -- a set of related
descriptions bundled together for practical purposes in a
single metadata "record".

Yes, we need to use a terminology related as recognizably as
possible to things already familiar to the intended reader,
but we also need to point out to readers where perspectives
differ.  On this point, I suggest we find a way to say
that "records" may provide descriptive statements "about"
more than one something.
