At The Semantic Technology and Business conference in San Francisco Monday, OCLC technology evangelist Richard Wallis broke the news that Content-negotiation was implemented for the publication of Linked Data for WorldCat resources. Last June, WorldCat.org began publishing Linked Data for its bibliographic treasure trove, a global catalog of more than 290 million library records and some 2 billion holdings, leveraging schema.org to describe the assets.
“Now you can use standard Linked Data technologies to bring back information in RDF/ XML, JSON, or Turtle,” Wallis said. Or triples. “People can start playing with this today.” As he writes in his blog discussing the news, they can manually specify their preferred serialization format to work with or display, or do it from within a program by specifying to the http protocol for the format to accept from accessing the URI.
“Two hundred ninety million records on the web of Linked Data is a pretty good chunk of stuff when you start talking content negotiation,” Wallis told the Semantic Web Blog.
