It's more accurate to say that the working group
influences and promotes (though, again, the marketing folks get confused when you use this term) the open source projects (especially the work of the Specification Projects). There is no direct governance relationship between the working group and any open source project. The specification process will likely define touch points during the development/release cycle where the Specification Committee has some formal role to ensure that they are in sync with the project team (we might argue that this is a governance role).
The Jakarta EE Platform project will have its own releases. It will consume the artifacts produced by releases of other projects. It does not "Manage, Release" any other projects.
The EE4J PMC provides governance for
all EE4J Projects. This includes spec and implementation projects.
IMHO, the IP Team doesn't belong on this diagram. It's the wrong level of granularity. The EMO provides a number of teams and services that support the open source projects, working groups, etc. I think that they're all implied for the purposes of this diagram.
HTH,
