Hello everybody,
I am new to UDIG. I want to use udig with WFS. I was able to use it
with WFS 1.0, but not with WFS 1.1. My question:- Is it even possible
to develop general purpose client for any WFS 1.1?
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)
What if my WFS schema is very complicated?
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.
In case of WFS 1.0 schemas are usually very simple, one just has to
look at a geometry field in the schema and use it for rendering. What
if there are multiple geometry fields or if there is topological
complex instead of a geometry field? Is it possible to create a
general purpose client without knowing the WFS application schema
beforehand? Any answers will be greatly appreciated. Thank you.
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
