Package org.jrdf Description

This top level package consists of Factories to construct on disk or in memory version of JRDF, optionally using Spring.

There is a difference between on disk and persistent JRDF graphs. On disk factories simply allow temporary graphs to be used without being restricted to available memory. Persistent graphs allow a name to be given to a graph which is stored on disk but can be reused across program runs.

Molecule factories create molecule stores which are an extension to RDF Graphs that allows them to be used in a distributed fashion (including blanks nodes).
