Transcript of "DM2E's EDM Application Profile - Evelyn Dröge"

  1. 1. DM2E‘s EDM Application Profile Data Model, Mappings and Documentation Evelyn Dröge Berlin School of Library and Information Science, Humboldt-Universität zu Berlin Presentation at the Meeting of National Europeana Partners Berlin, 08.11.2013 co-funded by the European Union
  2. 2. Introducing the DM2E Project Digitised Manuscripts to Europeana (DM2E) • EU-funded Europeana satelite project • Duration: Three years (2012 – 2015) • Partners from Germany, Austria, Norway, Greece, UK and Italy • Primary aims: To enable as many content providers as possible to get their data into Europeana and to stimulate the creation of new tools and services for reuse of Europeana data in the Digital Humanities IBI at the Humboldt-Universität zu Berlin • Coordinates the project • Is further involved in modeling and in evolving the technical infrastructure 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 2
  3. 3. DM2E: Key Aspects • Content – Input formats: TEI, MAB2, MARC, EAD, METS/MODS Database content – Mappings to the DM2E model • Technology Content Technology Community Building – Mapping infrastructure – Tools for scholars • Community Building – Hackathons – Workshops 08.11.2013 DM2E E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 3
  4. 4. DM2E‘s EDM Application Profile: DM2E Model
  5. 5. Specialising the EDM Domain: Manuscripts Target groups: DM2Es data providers, Digital Humanities community First test data: TEI transcriptions of Wittgensteins manuscripts from the University of Bergen 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 5
  6. 6. Specialising the EDM II Creation of the DM2E model that specialises the EDM Creation of a first model Data analysis DM2E model Production of rich mappings 08.11.2013 Integration of provider feedback E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 6
  7. 7. The DM2E Model • Namespaces: – dm2e: <http://onto.dm2e.eu/schemas/dm2e/1.0/> . – dm2edata: <http://data.dm2e.eu/data/> . • Additional external vocabularies – Bibo, FaBiO, PROVIVO, VoID • Modelling analogue to EDM – Extensive use of properties instead of classes E.g., 52 new properties for edm:ProvidedCHO – If possible: direct reuse of external vocabularies 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 7

  10. 10. From Provider Formats to DM2E: Mappings
  11. 11. Mappings 1. Mint – Mapping tool by the National Technical University of Athens – Mapping via Drag and Drop 2. Coded Mappings – E.g. XSLT with Oxygen – Can be based on Mint Exports 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 11

  17. 17. Different Ways of Documentation
  18. 18. Documentation The DM2E model is documented in three different ways: 1. For human readers as a PDF manual. 2. For offline usage as a separate OWL file. 3. Machine-readable and online via Neologism. → The descriptions in all representations are equivalent. Advantages and Disadvantages: 1. PDF: Not useful for tools but easy to read for humans. 2. OWL-File: Can easily be produced and read but the entities are not Web-referenceable. 3. Neologism: RDF and HTML representation of entities but shows only entities within one Namespace. 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 18
  19. 19. Documentation: PDF and OWL The PDF and the OWL representations can be accessed via the project‘s website: dm2e.eu/document/#DM2EModelSpecification 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 19
  20. 20. Documentation: Neologism • Vocabulary publishing platform • Based on Drupal • Upload of ontologies (RDF, OWL) • Creation of new classes or properties onto.dm2e.eu/dm2e 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 20
  21. 21. Next Steps • Finalising the DM2E model – Open issues: uncertain timespans or creators – Consistency check – Update to the newest EDM version • Analysis of the mapped data – Leading to further model optimisations 08.11.2013 E. Dröge: DM2E‘s EDM Application Profile. Data Model, Mappings and Documentation. 21
