I agree with your sentiment here but, from what you imply at
http://futurelib.pbworks.com/w/page/29114548/MARC%20elements,
transformation in to something that would be recognisable by the
originators of the source Marc will be difficult - and yes ugly.

The refreshing thing about the work done by the BL is that they stepped
away from the 'record', modeled the things that make up the BnB domain.
Then they implemented processes to extract rich data from the source Marc,
enrich it with external links, and load it to an RDF representation of the
model.

On the way, embedded in the extraction/transformation/enrichment processes
there was much ugly data, but that was not exposed beyond the process.  An
approach I applaud, unlike muddying the waters by attempting to publish
vocabularies for every Marc tag you can think of.

Concern shared.   I would however lower my sights slightly by setting the
current objective to be 'Publishing bibliographic information as Linked
Data to become a valuable and useful part of a Web of Data'.   Using the
Semantic Web as a goal introduces even more vagueness and baggage.  I
firmly believe that establishing a linked web of data will eventually
underpin a Semantic Web, but  there is still a few steps to go before we
get anywhere near that.

This is not surprising and I believe, at this stage, it is not a problem.
Lets eat the elephant one bite at a time - I envisage a lengthy interim
phase where publishing linked bibliographic data derived from traditional
Marc records (using processes championed by a community such as CODE4LIB),
is the norm.  Cataloging processes and systems that use a Linked Data model
at the core should then emerge, to satisfy a then established need.
