With the maturation of this field, companies are now in a position to describe, package, and reuse application architectures. This is exactly what Rational Software is trying to do for what we call solution stacks. A solution stack is defined by the selection of a problem domain, a deployment infrastructure, a development infrastructure, and various project characteristics. For such a point in the development space, it seems possible to pre-build an entire application framework capturing the key architectural decisions for that application. The talk will describe how we can approach that task and what the outcome may look like.
