Description

This ticket is for a new module (provisionally called "jena-db-storage") that is a framework for building RDF databases. It abstracts the database in to "triples+quads", "prefixes" and transactional control.

public interface DatabaseRDF  {
    // Triples and Quads
    public StorageRDF getData();

    // Prefixes
    public StoragePrefixes getPrefixes();

    //Transactional} for this database.
    public Transactional getTransactional();
}
