How MARC can SPARQL!

Believe it or not, MARC can be indexed using SPARQL. Granted, RDF triplestores cannot index MARC/XML directly, but a literal transformation of MARC/XML into a standard RDF serialization is not that hard, and can prove to be a swift and direct way to retain MARC-originating data values for querying. The use cases may not be immediately obvious, but the analysis below is a starting point that provides evidence of the utility and efficiency of this approach for anyone seeking to try these methods out. To be clear, though, the proposal here is not to manage or exchange data directly in this form; only to enable query access to existing MARC data.
