Following the directive http://governance.openstack.org/reference/new-projects-requirements.html

OpenStack Mission Alignment:
The Congress project as outlined here https://wiki.openstack.org/wiki/Congress#What_is_Congress
has a very clear scope of purpose. "Congress aims to provide an extensible open-source framework for
governance and regulatory compliance across any cloud services (e.g. application, network, compute and
storage) within a dynamic infrastructure.

Following the 4 opens
Open Source:
Both Congress and Python-congressclient use the open source Apache v2.0 license. Neither of these
projects have any library dependencies that would restrict how the projects may be distributed or
deployed.

Open Community:
The Congress leadership is chosen by the contributors of the project. Thinrichs is currently the PTL.
The Congress project has regular IRC meetings https://wiki.openstack.org/wiki/Meetings/Congress and
everything is logged http://eavesdrop.openstack.org/meetings/congressteammeeting/

Open Development:
- All code reviews are through the OpenStack infra CI
https://review.openstack.org/#/q/status:open+project:stackforge/congress,n,z and
https://review.openstack.org/#/q/status:open+project:stackforge/python-congressclient,n,z
- Congress has core reviewers https://review.openstack.org/#/admin/groups/232,members and
gate tests.
- The Congress PTL acts as the liaison for cross-project teams
- Congress collaborates with OpenStack projects GBP, Murano, Nova, Heat, Mistral, Keystone, and Swift.
- Congress will contribute to Oslo as the opportunities arise.

Open Design:
- Congress started holding public design meetings at the Juno summit and will continue to do so.
