[James Leigh]

Hi all,

Just a quick status about the work so fare on integrating Mulgara and
Sesame.

Cheers,
James

The Good
      * Serves as a simple triple store using the Sesame API
      * Performance of simple join queries is fast
      * Supports both SPARQL and SeRQL queries
      * Supports URI context

The Bad
      * BNode contexts are not supported.
      * TimeZones are not supported (most important) - Paul
      * Midnight is not supported - Paul
      * Language tags are not supported - Paul
      * Calling rollback or close in the wrong state throws an exception
        - Andrae
      * BNodes are not mapped efficiently when using HTTP repository -
        Arjohn

The Ugly:
      * Replaced mousepushers date utility with xerces
        XMLGregorianCalendar. This sometimes fails when converting to
        local timezone for storage.
      * Replacing logger.info with logger.debug improved performance!
