Hi John,

If I'm correct you have data, and you want to throw away attributes?

Normally you can throw away what you want. Depending on the type of data
you have, you normally have either one column holding the Geometry
(Point, Polygon or Line) most often in Binary Form. OR (in case of a csv
dataset, you have indeed an x and y column). But besides that you can
have 1 or more optional attributes (I even think it is possible to have
None attributes).

Also depending on the type of data you have, there are often some
auxillary files (sometimes an index file, or a file containing
projection info etc)

The proof is in the eating :-) Just try.
