2. What I’ll present today
•Europeana in brief
•Our strategy for 2015-2020
•How and where Linked Open Data and Linked Open Data
technologies are key in realising it
•And of course I’ll try to answer any questions you may
have after the presentation!
9. ... and 45 colleagues in
The Hague, London, and
Athens
What we call “The Office”*
* *UK version of course, but officially no other comparisons...
10. We support a community of
2500+ members who
contribute ideas, effort, data,
technology, knowledge and
business opportunities
*
Our proposed governance model
31. A data model for Linked Data
●Places
oGeoNames 7.4M
●Concepts
oGEMET 8.5M
oDbpedia 1.2M
oGetty AAT 1M
●Agents
oDbpedia 150k
32. 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 allows mixing them!
34. Still many R&D efforts - do join in!!!
EuropeanaTech
community
In February 2015 we will host a EuropeanaTech conference. Exact
date to be announced.
38. Linked-data compatible data re-use channels
→Search API
Results in JSON-LD, RDF/XML
→Semantic markup in the portal
Schema.org, OpenGraph
→Linked Open Data prototypes
Content negotiation, RDF dumps, SPARQL endpoint, SKOS
repository
39. Europeana and partners provide open metadata
Metadata - descriptive object information
Content - digital objects on the site of the provider
Different options
Linked OPEN Data
CC
with an increasing proportion of links to Public Domain
marked and Creative Commons licensed media
40. Case file: Wikidata - Sum of All Paintings
•Wikidata - the crowdsourced linked database of facts
•CC0 a hard requirement
•User: Multichill asked himself: How can we get facts about
all paintings in the world into Wikidata?
•Multichill is good with bots BTW
•I’ll script a bot to fetch metadata about paintings from
Europeana! And write it into Wikidata
•My US friends can use DPLA
45. Some use cases helped by linked data
•Being findable in the first place on the major search
engines and social platforms
•Cross-language retrieval based on vocabularies
•Vocabulary based facets with multilingual facet labels
•Autocompletions with semantic disambiguation and
suggestions of related searches
•Inclusion of “knowledge cards” in search results
•Cross-linked entity pages for concepts, agents, place and
periods
•Being findable in the first place on the major search
engines and social platforms
46. Subject facet for the
WWI-theme, based
on localised SKOS-concepts,
so they
are...
48. Spot the Linked Open Data!
●CHO with identifier, resolves to this
HTML ‘cause we’re human
●Work with unique identifier,
http://dbpedia.org/page/Toccata_and_Fugu
e_in_D_minor,_BWV_538
●Description from Dbpedia or Freebase,
http://dbpedia.org/page/Toccata_and_Fugu
e_in_D_minor,_BWV_538
●Agent entity, created via semantic
enrichment or dereferencing a provided
URI,
http://dbpedia.org/page/Johann_Sebastian
_Bach
●Genre classification,
http://dbpedia.org/page/Toccata
●Similar items, by semantic distance
49. Entity pages for concepts, agents, periods
and places with links to other objects in
Europeana. Near endless browse!
