8. Making metadata work for Europeana
Building a search engine on top of metadata is difficult
Traditional metadata quality problems: correctness, coverage
Especially when data is so heterogeneous
100s of formats, multilingual data
We currently use a simple flat interoperability format (ESE)

9. More semantics-enabled services
Enhance access by semantics
Query expansion, clustering of results
Exploiting various relations: "located in", “more specific concept"…
Goal: to make richer data and services available to us and others
Semantics are already there, in original metadata
Thesauri, classifications…
ESE loses information

10. Building a "semantic layer” context

11. Matches interest for linked data in libraries, archives and museums
LOD-LAM

12. Available Linked Library Data

13. Available Library Linked Data
Element sets/schemas/ontologies
SKOS, Dublin Core, OAI-ORE…
Value vocabularies/thesauri/authority lists
LCSH, VIAF…
Datasets
British Library, Chronicling America…

14. Europeana and Linked Data
Provide trusted, reference data for cultural objects Promote the use of the technology Promoting the exchange of data in the community and with third parties: Open (meta)data!

15. Europeana and Linked Data

17. Some steps in production services

18. Re-use and linking Currently: GeoNames, GEMET…
Data re-use can be serendipitous!
From our domain (VIAF, UDC) or others (Eurovoc)
Multilingual resources are key for us

19. Europeana Data Model Representing objects & others: persons, places...
Linking to internal or external data sources
Separating original data from enrichments
Enabling domain-specific data profiles
Model re-uses existing vocabularies

20. data.europeana.eu Europeana Linked Open Data Pilot Fully open metadata
2.4 M objects
200 individual providers
15 countries
We created a Linked Open data pilot. Via word of mouth practically, we invited some of our partners to allow us to publish their data as LOD. This 3m data is now online.
If you want to know more, check Data.europeana.eu

21. Challenges of semantic technology
Really big impact on processes IF you wish so Requires a lot of education/evangelisation More complex data modeling is an art finding the right balance & linking to requirements Linking datasets remain difficult needs tooling, involvement of stakeholders

23. Ongoing work EDM implementation in Metadata enrichment Data harvesting
Search, browse etc.
Data publishing interfaces
Search API, Linked Open Data, data dumps, OAI-PMH…
Metadata enrichment

24. Summary: benefits of semantic technologies for Europeana
Vocabularies and datasets to re-use Flexible approach to building & re-using standards More flexible approach to interoperability custom vocabularies co-existing with standard ones No constraints on the granularity of the data model Technical ease of connecting and publishing data Vision relates to open data strategies

25. ISA? Contribution to data modeling and exchange
Core vocabularies give good hints on what is needed
Source of data for re-use
Helping our data to be re-used
ADMS
