OWSLib is a Python package for working with OGC web map and feature services. It provides a common API for accessing service metadata and wrappers for GetCapabilities, GetMap, and GetFeature requests.
It's the work on this software that made me so grumpy about WFS yesterday. OWSLib is designed to forward imagery and feature responses to the user, and raise an exception in the case of a W*S service exception. It would be nice to be able to do this just by inspecting response headers, without looking in the data, but that's not possible in the WFS case. My solution is to waive large data through, assuming success, and only check smaller responses. I think this will generally work, though it could be spoiled by enormous tracebacks that make their way into service exception messages.
