Owen- Another strategy for capturing MARC data in RDF is to convert it to MODS (we do this using the LoC MARC to MODS stylesheet: http://www.loc.gov/standards/marcxml/xslt/MARC21slim2MODS.xsl). From there, it's pretty easy to incorporate into RDF. There are some issues to be aware of, such as how to map the MODS XML names to predicates and how to handle elements that can appear in multiple places in the hierarchy.
