Irish Cataloguing and Indexing Group Annual Seminar 25th February 2011, Dublin, Ireland

Outline

• The European(a) metadata landscape• Metadata interoperability in libraries • Cross-domain metadata interoperability • Towards the future: the Europeana Data Model• Beyond metadata: full-text content

Europeana: the vision

“A digital library that is a single, direct and multilingual access point to the European cultural heritage.”

European Parliament, 27 September 2007

Europeana: the vision

“A unique resource for Europe's distributed cultural heritage… ensuring a common access to Europe's libraries, archives and museums. Horst Forster, Director, Digital Content & Cognitive Systems Information Society Directorate, European Commission

What is Europeana?

The European Library Application Profile for Objects

• Dublin Core Application Profile• Based on the Dublin Core Library Application Profile• Specific metadata terms added to support functionality

Can we learn from the libraries?

Metadata interoperability in the libraries

Europeana Semantic Elements

Europeana Semantic Elements

Europeana Semantic Elements (ESE) developed for the prototype (now on v3.3.1)•A Dublin Core-based application profile

• Cross-domain schema for heterogeneous data• Not able to capture the full semantics of provider’s data

•37 Dublin Core terms – to describe the objects• for search and display

•14 Europeana coined terms - used to support portal functionality• Need to have consistent (normalised) data for the portal to work

Towards the future: the Europeana Data Model

• New data structure for Europeana

• Moves beyond the Europeana Semantic Elements (ESE)• represents lowest common denominator for object metadata• forces interoperability• major drawback: richness of the original metadata is lost

• Goal of the Europeana Data Model • preserve richness of the original data while still allowing for

interoperability• Facilitate participation in the semantic web

Enables browsing through related objects

Moving towards semantic interoperabilitySemantic Network

Networked object representations

Moves metadata from 2 dimensions to 3

From isolated metadata islands….

Moving from XML to RDF....

XML represents knowledge as trees RDF represents knowledge as networks of nodes and graphs

Europeana Data Model (EDM)

•OAI-ORE for organisation of metadata about an object

•Dublin Core for metadata representation

•SKOS for vocabulary organisation

Europeana Data Model for Libraries

Europeana Data Model for Libraries

1. Understand the Europeana Data Model!2. Explore how we can apply the Europeana Data Model

to library metadata3. Validate the draft Europeana Data Model for libraries

with real-world metadata4. Implement the Europeana Data Model for libraries

with metadata from national, university and public libraries

5. Create library-specific documentation and training materials

Beyond metadata: full-text content

You don’t need metadata … it’s full-text after all !?!
