Stop, you're both right [1].  The (metadata, bits) pair is a
representation of the resource.  The resource is a depiction (a kind
of representation) of Shakespeare.  To some extent, 'represents' is
transitive, so, by transitivity, the (metadata, bits) pair also
represents Shakespeare.

Some, but not all, things which are true of Shakespeare's image are
true of that particular JPEG.

Clearer examples would be, perhaps, a map of medieval Edinburgh:

or a caricature of Richard Nixon:

or the MP3 for a particular recording of Beethoven's 6th:
