Hi,

I don't know too much about data warehousing.  In my mind it
is equated with holding all the data in a big database.  Perhaps
you could be more specific about the datawarehousing capabilities
you need for those of us not to "up" on such IT terms.

There is support in the MITAB library for indexing attribute fields but
the OGR library doesn't utilize it.  You could potentially write a small
standalone utility using MITAB to index fields, or we could work together
to add proper indexing support to the OGR MITAB driver. Ironically, the
OGR Shapefile driver actually uses the MITAB attribute indexing support to
build .dbf indexes in the mapinfo format.
