DiscoverEd currently relies on feeds or OAI-PMH to aggregate resources from a curator. Third-party curators may wish to provide a list of resources with additional metadata without the overhead or restrictions of providing feeds or OAI-PMH support. This specification describes a linked, structured data model for curating resources for DiscoverEd without feeds or OAI-PMH.

Use Cases

Third Party Curator

Sally is an agriculture science librarian and as part of her work has collected a set of educational materials related to irrigation. She is not the author of these materials, but has applied a standard taxonomy to them. Sally publishes these resources on an XHTML web page, with structured data describing the taxonomy terms related to each resource.

DiscoverEd can use her web page as a curator feed. The resources Sally has identified will be crawled, and the taxonomy metadata included in the page will be indexed and available for search.


  • A Curator can list resources on one or more XHTML+RDFa pages. Resources will be included in the index.
  • A Curator can include additional, arbitrary metadata about the Resource. The metadata provided will be included in the index, along with provenance information noting it's source (the Curator).

Open Questions

  • What is the appropriate vocabulary for describing resources?
    OAI-ORE supports a variety of serialization formats, has rich aggregation semantics, and can include additional metadata about resources.
