thanks a lot for your elaborate answer!
No problem. I actually completely forgot one, which is validation
capabilities. This was one of the main thrusts of Refraction's work on
GeoServer, and I still have not tried it out much, but the code is
quite solid. Please correct me if I'm wrong, but basically it allows
you define stricter parameters on which to allow features to be
inserted and updated. A normal wfs does no validation, it lets you put
anything and everything in, even completely broken geometries and
features that just don't belong. With the validation suite you can
define rules that features coming in must meet. There are a bunch of
pre-defined plugIns, such as LineNotTouchingPolygon, LinesNotOverlap,
SingleValue, ValidGeometry, ect. These plugIns are pretty easy to
write. And then you define a validation, like a NullZero plugin with
an id attribute, to make sure all the features coming in have valid
ids. We really should publicize this capability more, and point people
at the user guide to using it, as I know of no other WFS that has
anything like it.
I will clarify on the 'possibility to define not supported' category.
This
is because my tabs did not come like they should have in the e-mail.
I meant:
Possibility to define GML profiles (like the ESRI GML profile): not
supported???So my question is: can I tweak Geoserver in such a way that I can
output
the ESRI type of GML?
I've never looked at the ESRI type of gml, but yeah, you can tweak
GeoServer all sorts of ways to have it output the right profile. We
completely let you define your own profile, your namespace, your
attributes, ect. There is a gui for this, and if it is insufficient,
if you're doing some really weird things with your schemas, then you
can also just define a schema.xml file which will be returned to users
for the DescribeFeatureType. So my bet would be that you could
configure it for ESRI GML, as long as they're not doing anything really
weird. But I've never tested it myself. If anyone else on the list
has experience with this please sound in.
And please let the list know if and when you publish the results of the
survey, I for one would like to see the results, as I don't know much
about the other WFS's out there.
