  1. Edurep Middle-man in the Dutch educational content chain Bas Jonkers

  2. Dutch Educational Content Chain

  3. Educational Content Broker Interoperability between suppliers and users

  4. Suppliers • Cultural Heritage Institutes • Dutch institute for Sound and Vision • National Archive • Musea • Publishers • Traditional • Internet-based • Private collections • Content creation portals • Electronic Learning Environments • Educational Repositories

  5. Implementors • Content Creation Portals • Content Corner • Webmaker • E-Learning environments • Teletop, • Moodle, • StudieWeb, • Sharepoint, • (N@tschool, It’s Learning) • Education related mashups • Davindi, • Samen Zoeken, • Onderwijs Media Platform, • Digischool, …

  6. Current partners sharing 190,000+ metadata records

  7. Making interoperability work Both technically and semantically

  8. Technical Interoperability Interfaces In: OAI PMH Out: SRU/SRW, SRU Drilldown, RSS Query language: CQL Fundamental choices • Open, widely accepted Standards only • Harvesting, no federated Search • No implementor specific features • No supplier specific exclusion rules • Implementors may target specific sets in Edurep

  9. Semantic Interoperability • Content Zoekprofiel (CZP) Dutch IEEE-LOM application profile agreed upon by the joint educational partners. • A growing set of standardized vocabularies (vdex’s) Educational levels, disciplines, … Fundamental choices • Suppliers are obliged to conform to CZP • Implementors can anticipate CZP metadatastructure in their query building and UI design

  10. Recent enhancements (2007) • Metadatastructure X to CZP Transformation facility (XSLT) • Static collection ingest facility (xml-upload) as an alternative to harvesting (initial fase only!)

  11. Architecture Content Creation Tools Portals e-Learning Env. other Edu-Mashups SRU/SRW, RSS Edurep Search Engine OAI PMH CZP Metadata Transformer OAI PMH Static sets Repositories

  12. Implementation Support - Edurep Wiki

  13. Implementation Support - Edurep Demonstrator

  14. Edurep User Group Members • Suppliers • Implementers • Kennisnet Main responsibilities • Evaluation • Roadmap decisions • Pollution control • Enforcing CZP compliance among members

  15. Roadmap 2008 (1) Support for Outbound OAI PMH • Allowing implementors to do their domain specific things • Enabling connection to international networks, such as Learning Resource Exhange (LRE), Ariadne, GLOBE

  16. Roadmap 2008 (2) Social Metadata Brokering (experimental) • Collecting and distributing: • Tags • Ratings • Peer reviews In relation to more formal metadata

  17. Roadmap 2008 (3) Automatic Metadata Extraction (experimental) object + context > CZP Objecttypes: • Text • Video

  18. Open source software components • Search Engine + harvester: • Meresco (www.meresco.org) • Metadata storage + oai provider: • Fedora (www.fedora.info) • Proai (proai.sourceforge.org) • Metadata transformer • Future Kennisnet OS-component (workflow requires more fine-tuning)
