  1. 1. The Europeana Data ModelLargely based on the slides by Antoine Isaacwith input from Carlo Meghini, Guus Schreiber,Stefan Gradmann, Makx Dekkers et al. fromEuropeana v1.0Talk by Steffen Hennicke (HU-Berlin)DM2E, WP2 Modeling Workshop, March 28th @ FU Berlin
  2. 2. EDM vs. ESEChallenge for Europeana: (Rich) Integration of heterogeneous CH-metadata.Precursor of EDM: Europeana Semantic Elements (ESE)• Used in first version of Europeana• Represents lowest common denominator for object metadata Converts datasets to Dublin-Core like “flat” standard• Forces interoperability “Simple and robust” approach but Original metadata is lost No easy connection to external contextualization resources“Europeana Data Model” 2DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
  3. 3. ESE Metadata Record“Europeana Data Model” 3DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
  4. 4. EDM Requirements & Principles1. Distinction between “provided objects” (painting, book, movie, etc.) and their digital representations2. Distinction between “provided objects” and metadata records describing an object3. Allow for multiple records (“views”) on one object, containing potentially contradictory statements about it4. Support for objects that are composed of other objects (“complex objects”)5. Compatibility with different levels of description6. Standard metadata format that can be specialized7. Support for contextual resources, including concepts from controlled vocabularies“Europeana Data Model” 4DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
  5. 5. EDM and other OntologiesUsing Semantic Web representation principles (RDF)• Re-use and mix different vocabularies together• Preserve original data and still allow for interoperability (Req. 6)• OAI ORE (Open Archives Initiative Object Reuse & Exchange) for organizing an object’s metadata and representation(s) • Req. 1-4• Dublin Core for descriptive metadata representation • Req. 5• SKOS (Simple Knowledge Organization System) for conceptual vocabulary representation • Req. 7• Some constructs are inspired by CIDOC-CRM“Europeana Data Model” 5DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
  6. 6. EDM “Core Pattern” A data provider submits to Europeana a logical “bundle” of an object plus its digital representation(s). The Aggregation organizes data of a provider. any „view“ related to the CHOthe „complex construct“of related resources(e.g. metadata record) the „described object“ or „object of interest“ “Europeana Data Model” 7 DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin

  40. 40. Current Status of EDM• There will always be potential enhancements to EDM• Important: we now have a stable version, so issues and new features have quite clear bounds • Confirmed feasibility in community workshops (Archives, Libraries, AudioVisual, Museums) • Closely articulated with Danube requirement process• First batches of EDM data • Europeana Linked Data pilot (data.europeana.eu) • Projects: MIMO, CARARE…“Europeana Data Model” 41DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
  41. 41. ESE, EDM and Data Providers’Duties & Benefits• EDM is backwards compatible with ESE • Object metadata described in ESE can be ingested and used in Europeana Danube release• Direct conversion of object data to EDM has benefits • Closer to original metadata • Data can be contextualized, semantically linked to other data • Allows for richer semantic query expansion & cross-collection browsing“Europeana Data Model” 42DM2E - WP2 Modeling Workshop, March 28th @ FU Berlin
