Hi, As a first contribution, I recently worked on a small bug about bad error response when passing incorrect parameters in API requests (#1110435<https://bugs.launchpad.net/keystone/+bug/1110435> ). There is also this other bug about bad application behavior when API requests data are incorrect or missing (#999084<https://bugs.launchpad.net/keystone/+bug/999084> ) My point is that no systematic data validation seems to be made when receiving API requests, leading to potential unwanted behavior or instability. I am working on a prototype to enable simple validation of all API requests data using json schemas and the python package jsonschema<https://pypi.python.org/pypi/jsonschema> . As I am new in the openstack community and also because my work uses the json schema specification which is still a draft with a new package dependency, I was looking for some feedback about this idea before going on and filling a blueprint.
