I would see entity engine and service engine as separate modules. Each module should have clearly defined api defining how they interact with the outside world. A clearly defined api will facilitate swapping parts. For example, the entity engine could be replaced with a hibernate based engine as long as the api was implemented.
(also there would be a module for Birt) On Fri, Sep 17, 2010 at 2:06 PM, BJ Freeman <bjf...@free-man.net> wrote: > to me framework is what has not ability to interact with the real world, > like party, but just the tools. > so base layer is Entity and service engine. > Next layer is Webapp and Widgets. > next layer is Webtools > next layer is security and common > > A person should be able to enable those things that they want for their > application. > > > > chris snow sent the following on 9/17/2010 4:11 AM: >> >> If you follow my instructions for 9.04 that will to a large extent >> give you framework independence. >> >> I think 9.04 makes a good basis for looking at modularising parts of >> ofbiz.
