Automated support for framework-based software

In this paper, we show how elaborate support for framework-based software evolution can be provided based on explicit documentation of the hot spots of object-oriented application frameworks. Such support includes high-level transformations that guide a developer when instantiating applications from a framework by propagating the necessary changes, as well as application upgrading facilities based on these transformations. The approach relies on active declarative documentation of the design and evolution of the framework´s hot spots, by means of metapatterns and their associated transformations.
