is this the right place, I mean this db-sig, to propose that something
like this be included in the next version of db-api?

also: my initial posting was about trying to get something like...

... something like <GeoTypes or whatever else performing good enough>
into Python, so that we could have a reference class hierarchy for
OpenGIS objects, something that a db-api compliant module can rely on,
rather than something that can use a db-api compliant module.

the situation at the moment is that we have no reference class hierarchy
for OpenGIS objects *and* that db-api compliant modules do not offer a
standardized way to transform OpenGIS data from python to db and back.

reading with interest the reactions from the group.


Never, under any circumstances, take a sleeping pill 
and a laxative on the same night.
