Denis' variation involves 13 chunks:

[1] Common = tests + common + usage

[1] Xulrunner = xulrunner 

[2] AppServer = as + archives + jmx -> depends on Common

[2] Freemarker = freemarker -> depends on Common

[2] Datatools = hibernate + birt -> depends on Common

[2] GWT = gwt -> depends on Common

[2] Web Services = WS -> depends on Common 

[2] Forge = Forge -> depends on Common 

[3] OpenShift = OpenShift -> depends on Common + AppServer

[5] JEE = vpe + struts + jsf + jst + cdi + seam + portlet -> depends on Xulrunner + Common + AppServer + Datatools

[6] Runtime = Runtime -> depends on Common + AppServer + Datatools + JEE + Xulrunner

[7] Maven = maven -> depends on Runtime + JEE + Common + AppServer + Datatools + Xulrunner

[9] Central = central + examples -> depends on Maven + Freemarker + Runtime + JEE + Common + AppServer + Datatools + Xulrunner

> As part of the planned migration to git [0] it's been suggested that we combine some of the existing components into larger groups [1] so that it's more manageable in terms of checking out sources and tagging/branching [2]. 
> Because 25 is a large number, and 1 is a small number, and we need some happy compromise.
> Here's my proposal for how to divide the JBT 4.0 sources into 7 github repos (chunks), comprising 4 tiers of dependency. This is akin to the +0, +1, +2, +3 labels assigned to projects within the annual Eclipse release trains [3], used to define delivery times based on dependencies between projects.
> {code:title=TIER 0: no upstream JBoss.org chunks}
> Base = tests + common + usage
> {code}
> {code:title=TIER 1: 1 upstream chunk, Base}
> AppServer = openshift + as + archives + jmx
>   -> depends on Base
> Hibernate/Birt/Freemarker = hibernate + birt + freemarker
>   -> depends on Base
> Visual Editing = vpe + xulrunner + gwt + struts + jsf + jst + cdi
>   -> depends on Base
> Web Services = WS + Forge
>   -> Depends on Base
> {code}
> {code:title=TIER 2: 4 upstream chunks}
> Seam/Runtime = Seam + Runtime 
>   -> depends on Hib + Vis + AppServer + Base
> {code}
> {code:title=TIER 3: 5 upstream chunks}
> Central/Examples/Maven/Portlet = central + examples + maven + portlet
>   -> depends on Seam/Runtime + Hib + Vis + AppServer + Base
> {code}
> I'm not thrilled with the names of the chunks, as something like "Central/Examples/Maven/Portlet" doesn't exactly roll off the tongue. If you have better names for the chunks, please suggest them.
> But regardless of name, I think the above separation of concerns, and the implied build sequence workflow makes a lot of sense.

They are labeled +0, +1, +2, and +3, with +0 coming first (the Platform) and +3 coming last (EPP). Projects themselves decide if they are +0, +1, +2, or +3."
