Downloadable data sets [OCLC].
DUBLIN, Ohio, USA, 14 August 2012—OCLC has published bibliographic linked data for the most widely held works in WorldCat. This downloadable file—representing nearly 1.2 million resources—contains approximately 80 million linked data “triples,” the term for the most granular relationship possible between discrete pieces of information.
“This is an important step for libraries and linked data,” said Richard Wallis, OCLC Technology Evangelist. “Organizations wishing to develop linked data services can experiment with this data set before going into full development. They’ll also be able to stress-test new services using a very large and important set of up-to-date, linked library data. We are really interested to see what people will do with this data.”
The linked data is provided as RDF serialization, and uses the Schema.org ontology as well as library extensions to Schema.org that OCLC has been working on with members and partners over the last year. It is being made available, under an ODC-BY data license, in a single, 1-gigabyte, compressed (GZip) file, which can be downloaded from here.
