[openstack-dev] [all] Proposal: Architecture Working Group

In your original email, you proposed "So, with that, I'd like to propose the creation of an Architecture Working Group. This group's charge would not be design by committee, but a place for architects to share their designs and gain support across projects to move forward with and ratify architectural decisions."

I like parts of this, and parts of this trouble me. But, I volunteered to be part of this activity because I have a real problem that this group could help me solve and I bet there are others who have this problem as well.

As you say, there are often problems, questions, and challenges of an architectural nature, that have a scope larger than a single project. I would like there to be a forum whose primary focus is to provide an avenue where these can be discussed. I would like it to be a place less noisy than "take it to the ML" and be a place where one could pose these questions and potentially discuss solutions that other projects have adopted.

The part I'm uncomfortable is the implied decision making authority of "ratifying architectural decisions". To ratify implies the ability to make official, the ability to "approve and sanction formally" and I ask whence came this power and authority?

Who currently has this power and authority, and is that individual or group delegating it to this working group?

While this ML thread is very interesting, it is also beginning to fragment and I would like to propose a spec in Gerrit with a draft charter for this working group and a review there.
