One option is to use jsonschema (https://pypi.python.org/pypi/jsonschema). A jsonschema validator object can be used to check each resource against an appropriate schema for that resource. If the validation passes, the request can follow the existing flow of control to the resource manager to the backend. If the request body parameters fail the validation specified by the resource schema, a validation error will be returned from the server.
