public final class RepositoryHarvester
extends org.eaglei.search.provider.rdf.AbstractRDFProvider

Extension of AbstractRDFProvider that uses the Repository /harvest API (see /harvest REST API spec for details).

• The results from the harvest call (returned in SPARQL tabular format) are parsed into a set of SPARQL QuerySolutions.
• The QuerySolutions are used to create a set of SearchResults (one search result for each unique subject URI).
• The SearchResults are gathered together into a SearchResultSet.
