Hi,
I've just tried to add the WPS module to the community
nightly build. Is someone interested to try it out
and see if if works? Don't have time to try it out
myself.
At the current stage of development the WPS can
trade feature collections in a few formats (GML2, GML2,
GeoJSon, zipped shapefiles), raw geometries (GML2, GML3,
WKT), bounding boxes, coverages in geotiff and arcgrid
format.
It has a ton of processes, many of them courtesy of
Sextante, some (45) JTS based, some others that I'm
building (like importing data in the catalog, collection
aggregations, and so on).
It can grab data from remote WFS servers and directly
access the catalog if you try to use the local WFS
and WCS servers using the special "http://geoserver/wfs"
and "http://geoserver/wcs" urls (no intermediate parsing
required).
It has a tool in the demo section of the GUI that
somewhat helps to build a request (knowledge of WPS
is still required, but at least you don't have
to painfully write down 200loc of XML to make a request,
it will do that for you).
That said, there is still a mountain of stuff to be done,
enough to keep busy a small army of coders:
- no support for asynch execution
- no support for KVP Execute request
- many Sextante processes do not actually run, there are
issues with binding the data types they expose. The integration
with Sextante is really messy and should be rewritten
- no limits on the size of the input/outputs, meaning
not ready for production
- of course when it comes to processes sky's the limit
so you can look for other process libraries to bind
or make your own (some days ago looked into the
integration of jgrasstools, which looks very nice, but
unfortunately seems to require java 6...)
- Make the request builder more user friendly
So if the topic interests you, please join and help.
There is a big meal to be cooked here and only one
cook in the kitchen....
Cheers
Andrea
