-------------------------------------

Lewis,  Cris,

We have a very well refined version here at JPL for Apache version 0.2.

The link supplied was at a point long ago before we achieved stability, and
efficiency.

The code here is blocked in migration by lack of developer resources to
perform the migration.

Nice. Thanks Chris.

the JPL filemanager to a place at Apache.
more efficient for most databases as it is a true relational structure.
 This will also add in the "ComplexQuery" feature that exists in the JPL
branch.

> This issue is to port the ColumnedBasedCatalog back-end that works with the 
> JPL filemanager to a place at Apache.
> It uses a column-based table structure in the database back-end, which is 
> more efficient for most databases as it is a true relational structure.  This 
> will also add in the "ComplexQuery" feature that exists in the JPL branch.
