This Committee was formed during the OpenStack Ice House Summit in Hong Kong by Board Resolution on 11/4.

Interop Working Group sets base requirements by defining 1) capabilities, 2) code and 3) must-pass tests for all OpenStack products. This definition uses community resources and involvement to drive interoperability by creating the minimum standards for products labelled "OpenStack."

Our mission is to define "OpenStack Core" that is supported by all implementations as chartered by the by-laws.

Objective / Scope

The Interop Working Group is around how the OpenStack brand is applied for commercial uses. Initially, this focus is on "what is core" and sustaining that definition over time. The scope will likely expand since the brand is an ongoing concern related to specialized marks and other use cases.

There are three ways in which the community uses the OpenStack brand including referring to projects.

  1. General community use of the mark
  2. Project-specific use associated with development activity
  3. Governed commercial use

While the top two of these uses are out of the scope of the Interop Working Group, the committee has a need to participate in the discussion to ensure consistent and clear use.
