A new offer is now available in the Linked Data Service of the German National Library.
The new SPARQL endpoint enables semantic querying of the library’s data via both a web and a machine interface. Under https://sparql.dnb.de, for example, questions such as “Which titles that appeared after 2010 are tagged with ‘KI’ and were written by authors who are known as philosophers?” or “How has the frequency of the keyword ‘Feminism’ developed since 1900?” can be answered.
