Justin (CCed) on this email is part of OWS-4 project, and has ported the
code in question over to GeoTools trunk.
If possible it would be great to see your work made public as a
GeoServer community module.

Jody,
Thank for your reply. I am a PhD student at George Mason University.
We are part of OWS-4 testbed. We are resposible for creating a
"clipping service" and wrap it as a WPS (Web Processing Service). We
have already created the basic version of the service which works with
WFS 1.0 using geotools and JTS. But at some point in the future we
have to upgrade it to WFS 1.1.
Can you send send me the links to the schema parser you are talking
about? If I can contribute to your project somehow, please let me
know. Can I get the geotools steering document? Any pointers on how to
start with UDIG source code would be helpful. Thank you.

Of course. We did one for the OWS-3 project that you can take a
look at,
we did not roll it out into the codebase as we only managed to parse
points as far as geometry went. But now geotools has picked up the
work
so we could do better - just need time / money / volunteers
(preferably
all three)

This is why we had to develop our own parser (our WFS 1.0 support is
done with the generation 3 geotools parser, the WFS 1.1 mentioned
above
using generation 4). The feature model used has also been a blocker,
but that has gotten some research attention since this time last
year,
now we need some development time to bring it home. Currently the
ground
work will be ready to do this for next year, but we make work on
funding
for that :-)
I got a geotools steering document to present to their project
management committee about that.

Sure, and we do this. So far we have been limited by data sources
presenting interesting content (so our current tools have not been
tested with more then one geometry field per feature etc...).
Um I have lots of links to this work ... what are you interested in?
Anything beyond it can be done?
Cheers,
Jody
