Following up on the earlier announcement that the British Library has made the British National Bibliography available under a public domain dedication, the JISC Open Bibliography project has worked to make this data more useable.
The data has been loaded into a Virtuoso store that is queriable through the SPARQL Endpoint and the URIs that we have assigned each record use the ORDF software to make them dereferencable, supporting perform content auto-negotiation as well as embedding RDFa in the HTML representation.
The data contains some 3 million individual records and some 173 million triples. Indexing the data was a very CPU intensive process taking approximately three days. Transforming and loading the source data took about five hours.
