Solving the OER “discovery problem”: the DiscoverEd prototype Ahrash N Bissell and  Nathan Yergler
Statement of the “problem” <ul><li>Smaller audience sizes -> smaller auto-generated datasets (e.g., via links).
Many valuable metadata fields are ill suited to automatic discovery.
Problem of authority. Who says?
Scalability. The OER movement is a global effort.
No universal standards for ontologies, and probably never will be.  </li></ul>
One view of the current “licensing landscape”
Structured data requirements for enhanced search and disocvery
Different curators. Different types and numbers of structured data (if any).
RDFa as a core element of a solution <ul><li>Independence and extensibility
Human- and machine-readable formats are the same (“don't repeat yourself”)
