<p class="MsoNormal">Hi,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">As a first contribution, I recently worked on a small bug about bad error response when passing incorrect parameters in API requests (<span style="font-size:9.0pt;font-family:"Ubuntu","sans-serif";color:#666666"><a href="https://bugs.launchpad.net/keystone/+bug/1110435">#1110435</a></span>).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">There is also this other bug about bad application behavior when API requests data are incorrect or missing (<a href="https://bugs.launchpad.net/keystone/+bug/999084">#999084</a>)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">My point is that no systematic data validation seems to be made when receiving API requests, leading to potential unwanted behavior or instability.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I am working on a prototype to enable simple validation of all API requests data using json schemas and the python package
<a href="https://pypi.python.org/pypi/jsonschema">jsonschema</a>.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">Regards,<o:p></o:p></p>
