If you want to work specifically with that dataset you could download the different parts Karen pointed you to, and convert to MARCXML using an efficient tool like yaz-marcdump [2]. yaz-marcdump is nice it will convert from MARC-8 to UTF-8. Once you've got it in MARCXML you could then use a stylesheet like LC's [2] to convert to DublinCore flavored RDF. This might be kinda lossy for your RDA work though, so you might want MARCXML->MODS [3], and then use the MODS->RDF conversion that the Simile folks created (which Karen also pointed you to) [4]. In fact Simile used that stylesheet on their own MIT Library Catalog MARC data (Barton) and still seem to have the result online [5]. So perhaps just using the Barton data is the quickest way to begin playing with what once was MARC data as RDF? To my knowledge Stefano Mazzocchi simply created an RDF vocabulary that mirrors the MODS XML Schema, but I haven't looked at it in a while. Another thing worth checking out might be Rob Styles work [6] with other people at Talis at converting MARC with full fidelity to RDF. Perhaps he has some tools (or data) at his disposal? Rob you are on here right? I'd be willing to lend a hand with some of this if necessary, so just let me know if you think I can help. //Ed [1] http://www.indexdata.com/yaz/doc/yaz-marcdump.tkl [2] http://www.loc.gov/standards/marcxml/xslt/MARC21slim2RDFDC.xsl [3] http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3.xsl [4] http://simile.mit.edu/wiki/MARC/MODS_RDFizer [5] http://simile.mit.edu/wiki/Dataset:_Barton [6] http://events.linkeddata.org/ldow2008/papers/02-styles-ayers-semantic-marc.pdf
