Schema.org and Libraries: Coming to a Consensus

Richard Wallis of DataLiberate recently wrote, “Back in September I formed a W3C Group – Schema Bib Extend.  To quote an old friend of mine ‘Why did you go and do that then?‘  Well, as I have mentioned before Schema.org has become a bit of a success story for structured data on the web.  I would have no hesitation in recommending it as a starting point for anyone, in any sector, wanting to share structured data on the web.  This is what OCLC did in the initial exercise to publish the 270+ million resources in WorldCat.org as Linked Data. At the same time, I believe that summer 2012 was a bit of a watershed for Linked Data in the library world.  Over the preceding few years we have had various national libraries publishing linked data (British LibraryBibliothèque nationale de FranceDeutsche National BibliothekNational Library of Sweden, to name just a few).  Read more

Download WorldCat Data as RDF Triples

Richard Wallis has written an article about the latest updates to WorldCat.org. He writes, “After we experimentally added RDFa embedded linked data, using Schema.org markup and some proposed Library extensions, to WorldCat pages, one the most often questions I was asked was where can I get my hands on some of this raw data? We are taking the application of linked data to WorldCat one step at a time so that we can learn from how people use and comment on it. So at that time if you wanted to see the raw data the only way was to use a tool [such as the W3C RDFA 1.1 Distiller] to parse the data out of the pages, just as the search engines do.” Read more

The Significance of WorldCat.org Linked Data Updates

Photo of Library interiorAs we reported a few days ago, WorldCat.org pages now include schema.org markup. Richard Wallis has provided further insight into this news in a new article: “OCLC have been at the leading edge of publishing bibliographic resources as linked data for several years.  At dewey.info they have been publishing the top levels of the Dewey classifications as linked data since 2009.  As announced yesterday, this has now been increased to encompass 32,000 terms, such as this one for the transits of Venus.  Also around for a few years is VIAF (the Virtual International Authorities File) where you will find URIs published for authors, such as this well known chap.  These two were more recently joined by FAST (Faceted Application of Subject Terminology), providing usefully applicable identifiers for Library of Congress Subject Headings and combinations thereof.” Read more
