Hmm, that reminds me ...

   'Representation' names a pair: a character sequence and a media type.

That's too simplified.  A representation is some amount of data and its
associated metadata that represents the state of some resource at a  
given
point in time [which resource and which point in time is usually  
indicated
outside the representation; e.g., in request method semantics, response
message status, and message metadata like the Date header field in  
HTTP].
The media type is only one of many metadata, and there certainly is no
requirement that the data be a "character sequence".  For example, a
JPEG picture of my dog is not a character sequence.
