Exploring linked classical music catalogs with OVERTURE

In this paper, we introduce OVERTURE--a web application allowing to explore the interlinked catalogs of major music libraries including the French National Library, Radio France and the Philharmonie de Paris. We have first developed the DOREMUS ontology which is an extension of the well-known FRBRoo model for describing works and expressions as well as the creation process. We have implemented a so-called marc2rdf tool allowing for the conversion and linking of bibliographical entries about music works, interpretations and expressions from their original MARC-format to RDF following this DOREMUS ontology. We present an exploratory search engine prototype that enables to browse through the reconciled collection of bibliographical records of classical music and to highlight the various interpretations of a work, its derivative, its performance casting as well as other rich metadata.
