layer to access and modify triple stores. It provides a java implementation of
the graph data model specified by W3C RDF
and functionalities to operate on that data model. SCB offers a service
interface to access multiple named graphs and it can use various weighted
providers to manage RDF graphs in a technology specific manner, e.g., using
Jena or Sesame. It also provides for adaptors that allow an application to use
Jena or Sesame APIs to process RDF graphs. Furthermore, SCB offers a
serialization and a parsing service to convert a graph into a certain
representation (format) and vice
versa.\n\t\t\t</div>"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> .
