OCWC Global 2009 Solving The OER Discovery Problem The DiscoverEd Prototype
Download as ODP, PDF1 like1,182 views
The document discusses the "discovery problem" in open educational resources (OER) where smaller datasets and a lack of standardized metadata makes it difficult to discover relevant resources. It proposes the DiscoverEd prototype which is built on the concept of "curators" who populate the system using structured data feeds. The DiscoverEd prototype integrates full-text and structured data indices, allows for customizable querying and data export, and its refinements are extensible. Going forward, the authors suggest improving provenance tracking, customization templates, and widgets for community metadata as well as personal search and communities of practice.

OCWC Global 2009 Solving The OER Discovery Problem The DiscoverEd Prototype
- 1. Solving the OER “discovery problem”: the DiscoverEd prototype Ahrash N Bissell and Nathan Yergler
- 2. Statement of the “problem” Smaller audience sizes -> smaller auto-generated datasets (e.g., via links).
- 3. Many valuable metadata fields are ill suited to automatic discovery.
- 4. Problem of authority. Who says?
- 5. Scalability. The OER movement is a global effort.
- 6. No universal standards for ontologies, and probably never will be.
- 7. One view of the current “licensing landscape”
- 8. Structured data requirements for enhanced search and disocvery
- 9. Different curators. Different types and numbers of structured data (if any).
- 10. RDFa as a core element of a solution Independence and extensibility
- 11. Human- and machine-readable formats are the same (“don't repeat yourself”)
- 12. Visual locality
- 14. Key attributes of the DiscoverEd prototype Built on the basis of “curators.”
- 16. Integrated full-text and structured data indices.
- 17. Open for any querying and data export.
- 19. Highly customizable on both front and back ends.
- 23. Where do we go from here? Tracking “provenance.”
- 25. Widgets for community-acquired metadata.
- 26. Personal search and communities of practice.
