The document discusses Europeana's strategy for 2015-2020 and how linked open data and linked open data technologies will help realize this strategy. Key points: - Europeana's strategy is to transition from metadata to graphs and from strings to things by making data and APIs more linked and open. - Linked open data allows data from different sources to be combined and helps make content more findable on search engines and in knowledge panels. - Europeana labs provides APIs, tools, documentation and data to help partners publish linked open data that can be reused in the Europeana portal and other applications.

1. The Europeana Strategy and Linked Open
Data
David Haskiya 2014-10-23

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!

3. Who are we?

4. What do we
mean by
‘we’?

5. We are
Europeana

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

17. Our services

18. Our strategy

19. Source: Enumerate

23. Platform
From records to graphs
APIs first!
From strings to things
IaaS and SaaS
From metadata to content

24. FROM

25. TO

27. Our 3 audiences

28. So, where does linked open
data really come in?

29. How can can we help data partners create
and share LOD?

30. Linked Open Data? What is it?

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!

33. Open Source inventory on Labs

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.

35. Long-term R&D effort example

36. How can can we serve this user better? By
using LOD?

37. Europeana Labs - APIs, tools, docs, data

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

41. Check out Crotos!

42. How can can we serve this user better? By
using LOD?

43. LOD to the
rescue!

44. LOD to the
rescue!

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...

47. ...multilingual
SKOS terms and
labels indexed in
SOLR

48. Spot the Linked Open Data!
●CHO with identifier, resolves to this
HTML ‘cause we’re human
●Work with unique identifier,

e_in_D_minor,_BWV_538
●Description from Dbpedia or Freebase,

●Agent entity, created via semantic
enrichment or dereferencing a provided

●Genre classification,

●Similar items, by semantic distance

49. Entity pages for concepts, agents, periods
and places with links to other objects in
Europeana. Near endless browse!
