To improve the developer experience of API users by converging the OpenStack API to a consistent and pragmatic RESTful design. The working group creates guidelines that all OpenStack projects should follow for new development, and promotes convergence of new APIs and future versions of existing APIs.
This document contains the guidelines and rules for OpenStack project APIs including guidelines and proposed rules concerning API consistency, naming conventions, and best practice recommendations.
