Matt's chicken-and-egg point seems dead-on. Except that Jack Dangermond
abhors a vacuum and ESRI has been focused on higher-order issues than file
formats. They are trying to provide topological constraints in the database
(or file) and things like geometric networks (which are really just a set of
ESRI Shapefiles use the ancient DBF format for attribute data. DBFs
restricts the length of field names. When I have to work with Shapefiles, I
try to stick to 8-character field names and avoid spaces and special
characters.

I've decided to just get some work done rather than focus on the Oracle
issues. Fortunately, the code I write with OGR using Shapefiles should work
seamlessly with Oracle (or relatively seamlessly).
But now I have a new problem. I am getting the following error when I call
exportToGML():

I'm using GDAL/OGR 1.6.1 with ActivePython 2.6.4-10 and cx_Oracle-5.0.3-11g.
I am trying to connect to an Oracle 11g instance.
This works:
ogr2ogr -f "KML" emp.kml OCI:scott/tiger "EMP"
What am I doing wrong. This fails, ds is None:
from osgeo import ogr
try:
d = ogr.GetDriverByName('O
