A distribution channel

What Europeana gets (and makes available)
Descriptive metadata
Link to digital objects online
![Page 6: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/6.jpg)
Making metadata work better
Creating a new Europeana Data Model

Prior to EDM: flat 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 e.g. between objects and context entities (persons, places)
Mixing data on real object and digital content
A lot of mapping quality problems

EDM: an example
![Page 9: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/9.jpg)
More granular metadata
![Page 10: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/10.jpg)
Harvesting thesauri as linked data
![Page 11: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/11.jpg)
Contextual resources – multilingual & semantic linked data for Concepts
<skos:Concept rdf:about="http://www.mimo-db.eu/InstrumentsKeywords/2251"> <skos:prefLabel xml:lang="">Harpsichord</skos:prefLabel> <skos:prefLabel xml:lang="de">Cembalo</skos:prefLabel> <skos:prefLabel xml:lang="sv">Cembalo</skos:prefLabel> <skos:prefLabel xml:lang="fr">Clavecin</skos:prefLabel> <skos:prefLabel xml:lang="it">Clavicembalo</skos:prefLabel> <skos:prefLabel xml:lang="en">Harpsichord</skos:prefLabel> <skos:prefLabel xml:lang="nl">Klavecimbel</skos:prefLabel> <skos:broader> <skos:Concept rdf:about="http://www.mimo-db.eu/InstrumentsKeywords/2239"/> </skos:broader></skos:Concept>

Contextual Resources – Places
![Page 13: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/13.jpg)
Collaborative, soft standardization
EDM is a cross-community development, involving library, archive and museum experts, plus academic partners
A data model that re-uses several existing Semantic Web-based models
![Page 14: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/14.jpg)
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
![Page 15: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/15.jpg)
Ready for metadata enrichment
Already re-using third-party sources
• GEMET, GeoNames, DBpedia
Enrichment by providers or Europeana
• In collaboration!
• Example: Getty vocabularieshttp://www.getty.edu/research/tools/vocabularies/lod/

Facilitating re-use
![Page 17: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/17.jpg)
Multiple 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
![Page 18: Semantic Web, Linked Data: the Europeana case(s)](https://reader035.vdocument.in/reader035/viewer/2022070313/554bc332b4c90530298b528d/html5/thumbnails/18.jpg)
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

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
