<br>
Thanks for picking this topic up,<br>
<br>
Honestly I don't have a strong opinion about validation libraries.<br>
Each project implements based on different web frameworks and<br>
the options of validation libraries would be limited from its web<br>
framework. For example, Nova implements its own wsgi framework and<br>
it is difficult to use pecan/wsme due to its API routing/parameter<br>
names. So Nova uses jsonschema for a new API(Nova v2.1 API) because<br>
of its flexibility and portability.<br>
>From quick seeing, stoplight seems flexible and it could cover many<br>
cases. That would be nice for me, but I'm not sure that stoplight is<br>
the best library because jsonschema is a common way/library and portable.<br>
<br>
Related to this topic, I'd like to suggest that we have common validation<br>
patterns across OpenStack projects. Now each project contains its owns<br>
validation patterns for the other project's resource. For example, Nova<br>
contains validation patterns for project-id and image-id on the code[1].<br>
Ideally, these validation patterns would be nice to be ported/shared from<br>
Keystone and Glance and it is the best to use the same validation patterns<br>
between whole OpenStack projects for consistent interfaces. Maybe we can<br>
implement these patterns even if using different validation libraries.<br>
