    https://github.com/apache/jena/pull/233
  
    Here's for starters.
    DatasetGaphThrift is a thrift based wrapper for an existing DatasetGaph. It 
includes a Java IFace and Server implementation and instructions on how to use 
another language to access the wrapped DSG. This allows a DSG to be accessed in 
another JVM. This is binary part.
    DatasetGaphMosaic wraps multiple DSG and presents them as one DSG. Useful 
when the wrapped DSG is a DSG thrift. It will apply optimistic locking and 
wraps the transaction with a try mechanism. Effectively MRMW with no contention 
unless writes are to the same DSG. This is clustering part.
    DatasetGaphMirage uses rules to auto magic quads based on the find methods. 
An example Ray is a folder which is mapped from between a urn: and file: schema 
and has the ability to load triples and quads to fulfill the find methods 
calls. This is dynamic part.
    Thrift I think is a candidate for core. Mosaic and Mirage I'm thinking more 
of an associated pom...

    What would a good start is an overview of what this covers.
    I'm looking for 2 things : what informs the core framework and what are new 
capabilities for systems/modules.
    This started with our discussions about binaries and binary protocols so 
that would be a good starting place.
