An agent (individual, organization, group) which identifies resources for inclusion in the DiscoverEd index. A curator may be creator/publisher of the resources, or may be a third party which identifies existing resources and [possibly] adds additional metadata. A curator provides one or more feeds identifying the resources to be indexed. (FIXME: Add an example curator.)


A list or map of resources to be included in the index. A feed is associated with a particular curator, and may also include metadata about the resource. Feed is used as a generic term to include Atom/RSS (parsed using Rome) and OAI-PMH endpoints. (FIXME: Add a sample feed curated by somebody.)


A single resource to be indexed, identified by a curator. Metadata about the resource may be included with it as RDFa, or provided by the curator. (FIXME: Link to a sample resource.)
