RDF cannot *redefine* resource, merely overload it - a source of much
confusion.

I take your point about 'parts and views'.

My intention was to get away from having to redefine anything from RFC2396,
hence the use of the vague term 'referent' - something pointed to.

Although RFC2396 does describe a fragment as a "partial view", their use in
RDF goes against the stated intent.  In section 4.1:

[[
   The semantics of a fragment identifier is a property of the data
   resulting from a retrieval action, regardless of the type of URI used
   in the reference.  Therefore, the format and interpretation of
   fragment identifiers is dependent on the media type [RFC2046] of the
   retrieval result.  The character restrictions described in Section 2
   for URI also apply to the fragment in a URI-reference.  Individual
   media types may define additional restrictions or structure within
   the fragment for specifying different types of "partial views" that
   can be identified within that media type.

   A fragment identifier is only meaningful when a URI reference is
   intended for retrieval and the result of that retrieval is a document
   for which the identified fragment is consistently defined.]]

This suggests to me that fragments operate over the bitstream fetched, not
on the abstract resource being accessed.  What are the arguments against
removing fragments from RDF?

Lee
