[Pywps-devel] creating GRASS locations per default

[Ludwig Max Brinckmann]

I think there are two issues: one is to support the WPS specfication, which
will require temporary storage and this should be defined in a common way.
The other issue are the requirements of different back-end environments,
such as GRASS. A generic WPS framework should none of this built in, as it
weighs things down for those who do not need it.
I think we do agree on this.

I would suggest abstracting GRASS support out into a base class for
processes that use GRASS, maybe as a mix-in class. Processes that use GRASS
would inherit from it, so all general GRASS stuff stays in one place.

Such a base class could also be the model for other framework adapters.

The way pyWPS is built it should not be difficult to achieve this.
