1. Europeana as a Linked Open Data case (in progress) Antoine Isaac ISKO UK Seminar “Making Metadata Work” London, June 23, 2014

2. Europe’s platform to access cultural heritage Currently 33M objects

3. Built on descriptive metadata from a broad, heterogeneous network Audiovisual collections National Aggregators Regional Aggregators Archives Thematic collections Libraries Musées Lausannois Culture.fr The European Library APEX European Film Gateway Europeana Fashion 2,300 galleries, museums, archives and libraries

4. What Europeana gets (and makes available) Descriptive metadata Link to digital objects online

5. A distribution channel

6. Linked Open Data? http://vimeo.com/36752317

7. Realizing Linked Data bits by bits Incremental progress on Europeana’s various facets  Data ingestion  Data enrichment  Front-end services: search, display  Data publication

8. Making metadata work better  Creating a new Europeana Data Model: EDM http://pro.europeana.eu/edm-documentation

9. Prior to EDM: flat metadata records dc:contributor, dc:creator, dc:date, dc:format, dc:identifier, dc:language, dc:publisher, dc:relation, dc:source, dcterms:alternative, dcterms:extent, dcterms:temporal, dcterms:medium, dcterms:created, dcterms:provenance, dcterms:issued, dcterms:conformsTo, dcterms:hasFormat, dcterms:isFormatOf, dcterms:hasVersion, dcterms:isVersionOf, dcterms:hasPart, dcterms:isPartOf, dcterms:isReferencedBy, dcterms:references, dcterms:isReplacedBy, dcterms:replaces dcterms:isRequiredBy, dcterms:requires dcterms:tableOfContents europeana:type, europeana:dataProvider, europeana:provider, europeana:isShownAt, europeana:isShownBy, europeana:object, europeana:rights  No links between objects and persons, places…  Mixing data on real object and digital content  Causing a lot of mapping quality problems

10. EDM: an example http://europeana.eu/portal/record/09102/_CM_0161930.html

11. Representing digital representations

12. More granular metadata

13. Contextual Resources – Places

14. Collaborative, soft standardization  Cross-community development, involving library, archive and museum experts and academic partners  Data model that re-uses several existing models Semantic Web paradigm just allows mixing them!

15. (Future work:) Different semantic grains  Adopts Semantic Web principle of specializing classes and properties  Enables extensions, “applications profiles”, based on needs and best practices from specific sectors or domains

16. Ready for metadata enrichment  Europeana links objects to third-party sources GEMET, GeoNames, DBpedia  Europeana providers send richer metadata

17. Harvesting thesauri as linked data

18. Contextual resources – multilingual & semantic linked data for Concepts Harpsichord Cembalo Clavecin Clavicembalo Harpsichord Klavecimbel

19. Contextual resource benefits - Work in progress  Allows to present users with richer context  Boosts multilingual search  And multilingual display

20. Linked-data compatible data re-use channels  Search API Results in JSON, JSON-LD, RDF/XML  Semantic mark-up on portal schema.org, OpenGraph  Linked Open Data prototype Content negotiation, RDF dumps, SPARQL endpoint

21. Content - digital objects on the site of the provider Metadata - descriptive object information Different options The legal side of data CC Europeana and partners provide open metadata

22. Technological advocacy hand in hand with legal advocacy http://vimeo.com/36752317

24. On practical aspects of enhancing semantic interoperability using SKOS and KOS alignment Antoine ISAAC KRR lab, Vrije Universiteit Amsterdam National Library of the Netherlands ISKO UK Meeting, July 21 2008, London

25. Enhancing semantic interoperability using SKOS Conclusion Representing KOSs using SKOS Main features Practical issues Demo SKOS and semantic alignment of KOSs  Despite some issues, SKOS provides a crucial contribution to enhance interoperability of KOSs

26. SKOS and Linked Data Antoine Isaac ISKO, London, Sept. 14 th 2010

27. Conclusion Publication and linking of linked KOS data is still work in progress, but We are now in position of realizing the issues and working towards solving them We can start building applications that make use of the wealth of data already available or yet to come Many KO resources to re-use and link to

28. Now: Getty Art and Architecture Thesaurus in SKOS Linked Open Data! http://www.getty.edu/research/tools/vocabularies/lod/

29. Now: Getty AAT in Europeana http://europeana.eu/portal/record/2023004/24062A23_priref_229.html

30. Now: Getty AAT in Europeana http://europeana.eu/portal/record/2023004/24062A23_priref_229.html

32. Still many R&D efforts EuropeanaTech community pro.europeana.eu/europeana-tech

33. Innovation - Searching http://eculture.cs.vu.nl/europeana/

34. Innovation - Annotation Pundit @ DM2E project http://dm2e.eu

35. Conclusions  Linked data presents big opportunities and challenges for Europeana and its partners  Not implementing the full technical stack at once already bring benefits
