Hungarian National Library OPAC and Digital Library Published as Linked Data

Courtesy of our colleagues in the SKOS community, we learned in April that the National Széchényi Library (NSZL) in Budapest has published its entire OPAC and Digital Library as Linked Data. The vocabularies employed are:

• RDFDC for bibliographic data
• FOAF for name authority entries
• SKOS for subject terms and geographical names

Adam Horvath, Director of Informatics at NSZL says:

Our RDFDC, FOAF and SKOS statements are linked together. Our name authority is matched with the DBPedia name files and URI aliases are handled as owl:sameAs statements.

This represents a significant achievement, and the Library is to be congratulated. Regrettably, the news came too late for this exemplar to be included in the forthcoming ISKO UK one-day conference on Linked Data on September 14th. Announcements will be made on the latter in the near future.
