So some vast improvements, and a step or two backwards.

On the bright side, the work in
http://knowledgeforge.net/pdw/trac/ticket/101
means we can now take MARC records and make sensible
RDF out of them -- probably the most complete such thing
out there if you look at the sample files (attached to this mail
and to the ticket).

In addition to the standard changeset layer, it includes

  * provenance information using OPMV, which includes the
     command line used to generate the data, should be
     sufficient for recreating it
  * proper handling of various types of identifiers -- this should
     be very helpful for deduplication. Wherever possible
     owl:sameAs links are made as well
  * proper handling of subject matter using controlled
     vocabularies where they are available (e.g. library of
     congress subject headings, etc) as well as proper representation
     of people when they are listed as a topic (e.g. biographies)

Much more to be done, the evolution of Work/Manifestation/
Item now has to be redone, and then a second pass at deduplication
(on the Work/Manifestation level) needs to be done. Fortunately
there should be provenance linkages to all source material so
you will be able to navigate down the whole tree to the individual
MARC record

Cheers,
