After about 5 weeks I'm finally getting back to this.  I hope everyone
else's minds are less clouded over than my own. :)

I have addressed all the elements of the evidence submodel to my liking
with the exception of representation.  I have a few questions for the
members of the LWG out there, as well as anyone who understands the
representation and representation-type elements. (and anyone else, as

source-id (FK)
representation-type-id (FK)
content (Text or multimedia)

representation-type-id (PK)

My questions are:
- First, what is a REPRESENTATION in the context of the GDM?
  Specifically, how does it relate to a digital encoding and physical
  representation? Is a photograph in my file cabinet a REPRESENTATION or
  is that a SOURCE in and of itself? Or are representations only
  encodings of the source that can be stored and transmitted? Most of
  the rest of the questions stem from this one.
- What is the difference between representation-type and medium?
- Physical-file-code combined with a physical representation would seem
  to be just another source that should be documented as such.

And a few comments:
- "One REPRESENTATION is a manifestation of one SOURCE" - so I will nest
  representation in source in the xml format.
- there are pre-existing standards for defining the location of things
  in 'cyberspace' and the type and encoding of the data: URIs and
  mime-types, respectively. I think it would be appropriate to bring
  those into play if appropriate. One consideration in doing this of
  course is that local URIs will only be valid on the local system (but
  then so would any way of citing a file on the local system).
- When content is a text transcription, it may be very appropriate to
  use TEI for encoding the text.
- When we wish to communicate an image or other binary format we could
  mime-encode it just as we do with email attachments.
