WorldCat Releases 197 Million Nuggets of Linked Data

By   /  April 30, 2014  /  No Comments

A new article by Data Liberate founder Richard Wallis reports, “A couple of months back I spoke about the preview release of Works data from WorldCat.org.”

worldcatRichard Wallis of OCLC reports on his Data Liberate blog, “A couple of months back I spoke about the preview release of Works data from WorldCat.org.  Today OCLC published a press release announcing the official release of 197 million descriptions of bibliographic Works. A Work is a high-level description of a resource, containing information such as author, name, descriptions, subjects etc., common to all editions of the work.  The description format is based upon some of the properties defined by the CreativeWork type from the Schema.org vocabulary.  In the case of a WorldCat Work description, it also contains [Linked Data] links to individual, OCLC numbered, editions already shared from WorldCat.org.”


Wallis continues, “They look a little different to the kind of metadata we are used to in the library world.  Check out this example and you will see that, apart from name and description strings, it is mostly links.  It is linked data after all. These links (URIs) lead, where available, to authoritative sources for people, subjects, etc.  When not available, placeholder URIs have been created to capture information not yet available or identified in such authoritative hubs.  As you would expect from a linked data hub the works are available in common RDF serializations – TurtleRDF/XMLN-TriplesJSON-LD – using the Schema.org vocabulary – under an open data license.”
