[Pywps-dev] pywps - json output

[Jachym Cepicky]

You are assuming, WPS is json-based format. But it's not. There are some
rather proprietary solutions around, but WPS is XML-based communication
protocol and PyWPS currently supports only XML in and output.

You can propose how we could implement JSON by pull request

if you want to interact with JSON, have a look at JSONIX [1], which should
have support for WPS too
