  • 2. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Linked data? 1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information, using the standards (RDF*, SPARQL) 4. Include links to other URIs, so that they can discover more things. Tim Berners Lee Design issues http://www.w3.org/DesignIssues/LinkedData.html
  • 3. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Linked data! Linked Data is a methodology for  providing relationships between things (data, concepts and documents)  anywhere on the web,  using URI’s for identifying,  RDF for describing  HTTP for publishing these things and relationships,  in a way that they can be interpreted and used by humans and software. http://commonplace.net/2009/06/linked-data-for-libraries/
  • 4. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Data is relationships Triples  subject-predicate-object  a person (subject) is the author of (predicate) a book (object)  a book (subject) is about (predicate) a person (object)
  • 5. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Relationships?  Entity Relationship Diagram
  • 6. 22 november, 2010 Dutch Culture Link - Lukas Koster University library On the web  Relationships  Not internal, within same database silo  External, with all kinds of web sources  “Things” identified by URIs  Relationships too!
  • 7. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Vocabularies (Ontologies) Datamodellen RDF – Resource Description Framework
  • 8. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Content negotiation
  • 9. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The Linked Open Data Project - partners  DEN – Digital Heritage Foundation of The Netherlands  Digital standards for heritage institutions  Promoting linked open data: museums, etc.  Simple guidelines  UBA – Library of the University of Amsterdam  TIN – Theater Institute of The Netherlands
  • 10. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The Linked Open Data Project - Objectives  Set an example  Proof of concept  Pilot  Convince heritage institutions  Convince TIN, UBA management Dutch Culture Link
  • 11. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The Linked Open Data Project – 2 viewpoints Publish Use
  • 12. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The TIN Collection  Theater performances  Metadata  Digital objects  Audio  Video  Images  Photos
  • 13. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The UBA OPAC  Metadata  Bibliographic  MARC
  • 14. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The TIN Collection Data model
  • 15. 22 november, 2010 Dutch Culture Link - Lukas Koster University library The TIN Collection Data model
  • 16. 22 november, 2010 Dutch Culture Link - Lukas Koster University library FRBR?  Work  Expression  Manifestation  Item  Play  Production  Production  Performance (translation?)  Play  Translation  Edition  Copy
  • 17. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Questions….  Which vocabulary/ontology?  How to implement RDF?  How to format URIs?  Which tools, techniques, languages?  How to find/get published linked data?  How to process retrieved linked data?
  • 18. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Training  Lots of sites, tutorials on line  Training: no money  DANS Linked Open Data workshop
  • 19. 22 november, 2010 Dutch Culture Link - Lukas Koster University library Quick and dirty  TIN  URIs for data entities  JSON  UBA  JavaScript: construct TIN URI  Process JSON  Present data in record AGILE!
  • 20. 22 november, 2010 Dutch Culture Link - Lukas Koster University library TIN  URI  <base-url>/person/<personname>  <base-url>/play/<personname>/<title>  <base-url>/production/<personname>/<title>/<opening>  <base-url>/performance/<personname>/<title>/<opening>/<datetime>  … Ad Aerts
  • 21. 22 november, 2010 Dutch Culture Link - Lukas Koster University library TIN – URI + JSON Example  <base-url>/person/Beckett, Samuel jsonTIN({ "key":"beckett, samuel", "name":"Beckett, Samuel", "birth.country":"Ierland", "birth.date":" 1906*", "birth.place":"Foxrock", "death.date":"1989-12-22", "death.place":"Parijs" })
