View source for DiscoverEd: Missing Metadata

The [[Universal Education Search]] project is an experimental search engine which uses [[CcLearn_Search_Metadata|metadata]] to enhance full text search results.  This metadata is gathered from a variety of sources, including OAI-PMH harvesting, RSS feeds and embedded [[RDFa]].  If a site does not provide the metadata in their feed or (preferably) as embedded RDFa, the search engine is unable to leverage it.
