Marty Kube updated MAHOUT-1164:
-------------------------------

    Status: Patch Available  (was: Open)

This patch adds a command line option to generate JSON meta-data.

The patch also improves the binary meta-data representation to include allowed 
values for enumerated types.  The improvement should be backwards compatibale 
as the additional data is tacked on at the end.

It's worth considering dropping support for the binary format.  I'm not sure 
who is using it...
