- Europeana is a digital library system that provides access to cultural heritage collections across Europe through APIs and a portal. - The Europeana Semantic Elements model is currently used but the Europeana Data Model is being developed to better preserve original metadata while enabling interoperability. - The Europeana Data Model presentation described the EDM, which is based on standards like OAI ORE, Dublin Core, and SKOS to organize object metadata from different providers in a semantic web framework. It allows distinction between objects and records while supporting complex objects and vocabularies.

- 37. Background reading • EDM Primer http://www.few.vu.nl/~aisaac/edm/EDM_Primer_100401.pdf
- 38. Rationale of EDM • Precursor: ESE (Europeana Semantic Elements) – used in 2008 version of Europeana – represents lowest common denominator for object metadata • convert datasets to Dublin-Core like standard – forces interoperability – major drawback: original metadata is lost • EDM goals – preserve original data while still allowing for interoperability • Semantic Web representation
- 39. EDM requirements 1. Distinction between “provided object” (painting, book, program) and digital representation 2. Distinction between object and metadata record describing an object . 3. Allow for multiple records for same object, containing potentially contradictory statements about an object 4. Support for objects that are composed of other objects 5. Standard metadata format that can be specialized 6. Standard vocabulary format that can be specialized 7. EDM should be based on existing standards – “not yes another standard” !
- 40. EDM basics • OAI ORE for organization of metadata about an object – Requirements 1-4 • Dublin Core for metadata representation – Requirement 5 • SKOS for vocabulary representation – Requirement 6 OAI ORE, Dublin Core and SKOS together fulfil Requirement-7!
- 41. EDM representation: RDF standard • Ovals are web resources with a URL • Arcs are properties linking resources to other resources or to literals • Resources belong to classes • RDF model can be specialized using subclass and subproperty definitions
- 42. Dublin Core • EDM uses the latest version of DCMI Metadata Terms http://dublincore.org/documents/dcmi-terms/ • Specified with an RDF model • Specialization of 15 original DC elements dcterms:coverage dcterms:spatial dcterms:temporal • Can be specialized itself – see requirement
- 43. SKOS: vocabulary publication on the Web • W3C standard http://www.w3.org/TR/skos-primer/ • Adopted by large institutions such as Library of Congress • Specified with an RDF model • Can be specialized itself
- 44. OAI ORE Open Archives Initiative Object Reuse & Exchange • Specification: http://www.openarchives.org/ore/1.0/toc.html • Specified with an RDF model • Four key notions (RDF classes) – Object: the book/painting/program being described – Aggregation: organizes object information from a particular provider (museum, archive, library) – Digital representation: some digital form of the object with a Web address – Proxy: the metadata record for the object
- 45. The Example - 1 45
- 46. The Example - 2 46
- 47. Aggregation organizes data of a provider provenance digital representation metadata aggregation object 47
- 48. Proxy: metadata record for an object object metadata proxy 48
- 49. Multiple aggregations = multiple providers aggregation of DMF aggregation of Louvre 49
- 50. Europeana is “just” a special provider with processed/enriched metadata Europeana aggregation 50 landing enriched page metadata
- 51. Advanced modeling in EDM • See the documentation • Relations between “provided” objects – Part-whole links for complex objects – Derivation and versioning relations • Predefined classes for person, place, time and event

The award-winning Where Once We Walked (WOWW) has been completely revised and updated to reflect the changes in the political geography of Central and Eastern Europe since WOWW was published in 1991. There are also a number of improvements to the original edition noted below. The new edition identifies more than 23,500 towns in Central and Eastern Europe where Jews lived
