[Live-demo] pywps to osgeo-live

Hi Cameron and OSGeo Live maintainers,

I'm strongly in favour of PyWPS being included in OSGeo Live 8.0. Admittedly it does not have a pretty GUI, but I'm not convinced that it ever should...

A fair number of OSGeo Live users are technically experienced and have a compelling need for the capabilities that command line tools and developer libraries provide (especially those tools that deliver Open Standards).

PyWPS is very well established, and I am aware of use cases in production environments.  OSGeo Live already has an excellent introduction to Web Processing Services via ZOO-Project - PyWPS complements this by making similar capabilities available to python developers once they are familiar with the concepts.  Instead of additional PyWPS documentation I would recommend a simple note: "See also: ZOO Project".  In my case I got to grips with WPS through the ZOO tutorials and then switched to PyWPS when I knew what I was doing but needed to do it in a Python environment.

Hopefully these thoughts are helpful,

Ian

Cameron

I disagree in most of your points.

Use case for PyWPS is the same as ZOO or 52North. If it is established and stable, I can not tell - community has to tell.

PyWPS is simple and focused application. Maybe we do not have web interface, but we know, where our position is

I have no time for this. I've forwarded it to pywps-dev list, maybe someone else will pick this issue.

Cheers

Jachym
