[owslib-devel] [owslib-users] WPS support

[Cinquini, Luca (3880)]

Hi all,
I transferred this conversation to owslib-devel...

I think having multiple implementation of client-side WPS functionality is certainly a good thing.
I was indeed aware of a JS implementation under development in the context or pywps, and I think it would be a very valuable tool for some apps.
In my personal case, I'd rather execute python invocation from within my django views and models, so building on top of OWSLib makes more sense.
Maybe the two approaches can even be combined...

In any case, I started looking at using the existing OWSlib classes to make WPS requests and parse WPS response, and it seems like it wouldn't be too difficult of a job.
Off course, I'll be happy to either collaborate at doing so, or simply using existing code. My timeline is somewhat short though, as I'd like to show some working prototype
within a couple of weeks. I can probably report more on how it's going sometimes next week.

thanks to all,
Luca
