1. Europeana
Linked Open Data Use Cases

2. What is
Europeana?

3. Europe’s platform to access cultural heritage
Currently
41M objects

4. What Europeana makes available
Metadata
Link to digital
objects online

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

6. Aggregating museum data
Individual museums may provide data directly, but the
vast majority goes/went through vast aggregators
 EuropeanaLocal
 ATHENA
 Linked Heritage
 various national aggregators

7. More than this

9. Multi-sided platform

13. Europeana and linked
open data

14. Content (digital objects on the site of the provider)
Metadata (descriptive object information)
Different
options
Open Metadata

18. How Europeana uses
linked open data

19. Prior to the Europeana Data Model: flat
records in Europeana
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 context entities (persons, places)
 Mixing data on real object and digital content
 A lot of mapping quality problems

20. EDM: an example

21. More granular metadata

22. Harvesting thesauri as linked data

23. Contextual Resources – Places

24. Ready for metadata enrichment
 Already re-using third-party sources
• GeoNames, DBpedia, AAT, GEMET…
 Enrichment by providers or Europeana
• In collaboration!
• Example: Getty vocabularies
http://www.getty.edu/research/tools
/vocabularies/lod/

25. Not just display and search
All this exists at the data level
Data is exported in our API
So data re-users can provide enhanced display and search
services to.

26. Not just AAT
Getty will release other vocabularies as linked data
Our partner projects use other linked data sets
Geonames, VIAF, GND, Iconclass, DBpedia, MIMO, PartagePlus

27. Europeana Automatic Enrichment

28. Modeling, linked data style
 Cross-community development
 Data models that re-use several existing models
Semantic Web paradigm just allows mixing them!

29. Different semantic grains
 Semantic Web principle of specializing
classes and properties
 Enables extensions, “applications
profiles”, based on needs and best
practices from specific sectors or
domains

30. Benefits of linked data for Europeana
Vision matches well open data strategies
Vocabularies and datasets to re-use for enrichment
Making data work better for search and display
Technical ease of publishing and connecting data
Flexible approach to building & re-using standards
More flexible approach to interoperability and granularity
of the data model

31. Advocating LOD http://vimeo.com/36752317

32. Further development - Searching

33. Browsing
Europeana Channels

34. Annotating
Pundit @ DM2E project http://dm2e.eu

35. Conclusions
 Big opportunities and challenges for Europeana and
its partners
 Not implementing the full Semantic Web technical
stack at once already bring benefits
 Seeing where the general Linked Data vision can
change things
