What is Europeana?
Europe’s platform to access cultural heritage
Currently41M objects
What Europeana makes available
Metadata
Link to digital objects online
Built on descriptive metadatafrom 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
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
More than this
Multi-sided platform
Europeana and linked open data
Content (digital objects on the site of the provider)
Metadata (descriptive object information)

How Europeana uses linked open data
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
EDM: an example
More granular metadata
Harvesting thesauri as linked data
Contextual Resources – Places
Ready for metadata enrichment
Already re-using third-party sources
• GeoNames, DBpedia, AAT, GEMET…
Enrichment by providers or Europeana
• In collaboration!
• Example: Getty vocabularieshttp://www.getty.edu/research/tools/vocabularies/lod/
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.
Not just AATGetty will release other vocabularies as linked data
Our partner projects use other linked data sets
Geonames, VIAF, GND, Iconclass, DBpedia, MIMO, PartagePlus
Europeana Automatic Enrichment
Modeling, linked data style
Cross-community development
Data models that re-use several existing models
Semantic Web paradigm just allows mixing them!
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
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

Further development - Searching
Browsing

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
