Property tables augment the Jena triple store by providing efficient storage for frequently occurring patterns of statements. They are space efficient in that the predicate URI of a statement is not stored. They are time efficient in that a single database operation can store or retrieve a set of RDF statements, encoded as a single table row. Property tables are less flexible than a triple store and the basic graph operations over property tables are more complicated. However, the core functionality enables Jena to access and update legacy relational database tables and so helps to bridge the divide between structured and semi-structured information.
