Anthony, I believe I have your comments worked into this doc, please
take a look.
Itamar, please review the two project rules.
Carl.

I was thinking of votes in term of VDSM, the Admin REST API. or we want
to add a reporting API etc. not the contents, just which team drives it,
and that it is an agreed point we 'support' with some or other ABI.
We should define that out a bit more.

I was trying to understand how something like QEMU would fit into oVirt.
Since this requires that the each project consumes or provides a
supported API, QEMU exposes an API that it supports (QMP), but it's not
published through oVirt (or would it be?). oVirt Engine consumes it via
a very indirect path (through VDSM, then through libvirt, and then QMP).
I don't think Apache has any real requirement that projects under
Apache.org integrates with apache directly, right? Maybe it would be
best if we avoided being overly specific here.
How does Eclipse handle this?

that is why I phrased it provides or consume directly or indirectly, to
cover these cases. That should cover things like QEMU or other modules
down the stack. It also allow for someone to build a proxy or something
else ontop of the REST API, and then have a project that uses that
project would also be able to be included.
The key is that engine is the 'glue' project and then we want to be able
to relate all project to it, either on top of the engine, or under it.
No, Apache has not such rule
How does Eclipse handle this?
Eclipse is the model here we want to use for this part. They have a set
of frameworks, a core platform which also ships as RCP (the morel
equivalent of or engine) and then a set of API. They also have an arch
list. All projects have to:
- integrate with the core framework (effectively RCP) {this means
cut/copy/ paste etc etc all work between the projects for example so
between WTP and STP even those there is zero overlap in dev between
these projects or between WTP and any 3rd party plugin}
then optionally support additional API's
- some projects also create API's for consumption, there is an arch team
that coordinates and agrees which projects expose project wide
supportable API's
The second rule is that each project must support the release schedule.
the project is free to choose what it is going to put onto the 'release
train' as they call it
They have a few more rules, but I think we only need these two to get
what we need to keep oVirt consistent and simple. As we mature we can as
needed.
I'll try find some docs on it and mail out the link for reference.
Carl.

For this paragraph:
"In order to release a cohesive stack, everything needs to work
together. The core of this is the engine. If a new project is started it
needs to integrate with a published API, or an additional API needs to
be created into the engine project to support the new project. Finally
additional API’s can come into scope to provide facilities/capabilities
that the engine consumes. The board signs off on which project provide
API’s to make sure there is coordination between the projects. The board
is not responsible for the technical aspects of the API’s, just the
facilitation when named API projects are added or removed."
It feels a bit out of place. Perhaps it's because I don't have a good
grip on what the "engine project" is since it still doesn't exist as an
open source project.
Maybe we can just drop this paragraph or remove the bits about the
engine? The rest looks great.

The engine is the core framework for us, as I posted in the piece on how
eclipse works. I would like to add it and we can discuss in more detail
in the governance tracks at the workshop and edit as required.
However to the point on related projects, I'm going to add a para on that

Okay, it makes sense re: eclipse but I think we need to come up with a
firm mission statement of the engine project.
The way it's positioned, if RHEV-M Server is oVirt Engine, then you're
excluding the possibility of having an stand alone VDSM with tools that
build directly on top of VDSM. If that's the case, then it dramatically
affects the type of ecosystem being built here.

The API restriction may be too much.
Assuming engine is RHEV-M, important projects similar to KSM[1]
will not be a part of oVirt, and we may end up loosing important innovations.
I'm not sure RHEV-M (engine) is fully equivalent to eclipse, and therefore
the API rule may harm us.
As I see it, either we define oVirt umbrella as an union model (rings around
rhev-m), and acknowledge the fact we'll be loosing projects, or use an
eco-environment
for visualization, by restricting the API rule to engin-related project, and
accepting other project which will commit to the other eco-system rule(s).

Sorry for mail my previous typo's (visualization -> virtualization,
engin->engine, etc).
One more thing I left out;
What I'm missing in this document is a review process to a new project.
IE- Do we accept any new project or do we have some minimal 'due diligence'
of the project.
For example;
- Who owns it?
- Is there some commitment behind it, or is it a 'one man show'?
- Does is have a malicious potential?
These are all examples I hope we won't need to face.
I think it should be considered and added into the document, if you feel the same.
