When the web moves from strings to things libraries can leverage on their authority data to improve the navigation in their catalogues and thus to help improve the user experience.
In this presentation held at a workshop organised by the URBS library community in Rome on November 18, 2013, I try to give theoretical and practical examples of how this can be implemented.

  7. 7. In the German speaking world, all authorities are collected in the GND GND PND 7 | 23 SWD GKD | Authority control and semantic interoperability | November 18, 2013 EST
  8. 8. The GND uses an entity-based model • • Conference or Event • Subject Heading • Work • Place or Geographic Name • Family • 8 | 23 Corporate Body Person | Authority control and semantic interoperability | November 18, 2013

In the DNB linked data service, we use GNDO to build authority representations <gnd:DifferentiatedPerson rdf:about="http://d-nb.info/gnd/118508288"> <gnd:publication>Grand Concerto pour le Piano forte. - s.a.</gnd:publication> <gnd:variantNameEntityForThePerson rdf:parseType="Resource"> <gnd:forename>...</gnd:forename> <gnd:surname>Beethofen</gnd:surname> </gnd:variantNameEntityForThePerson> <gnd:professionOrOccupation rdf:resource="http://d-nb.info/gnd/4032009-1"/> <gnd:placeOfActivity rdf:resource="http://d-nb.info/gnd/4007666-0"/> <gnd:publication>Werke. - s. a. abgeschlossen 1865</gnd:publication> <gnd:geographicAreaCode rdf:resource="http://d-nb.info/standards/vocab/gnd/geographic-area<gnd:oldAuthorityNumber>(DE-101c)127037454</gnd:oldAuthorityNumber> <gnd:variantNameEntityForThePerson rdf:parseType="Resource"> <gnd:prefix>van</gnd:prefix> <gnd:forename>Ludovicus</gnd:forename> <gnd:surname>Beethoven</gnd:surname> </gnd:variantNameEntityForThePerson> <gnd:variantNameEntityForThePerson rdf:parseType="Resource"> <gnd:prefix>van</gnd:prefix> <gnd:forename>Ludwig</gnd:forename> <gnd:surname>Bethoven</gnd:surname> </gnd:variantNameEntityForThePerson> […] 10 | 23 | Authority control and semantic interoperability | November 18, 2013
