In this paper we present an approach and a corresponding implementation-in the form of a Fujaba pluginfor refining models including their behavior. Our plugin enables Fujaba models to be annotated with refinement directives and supports the definition of corresponding refinement transformations with a combination of “Story-Driven-Modeling” and Java code. In this paper we motivate architecture stratification, describe how to define and use transformations, and present a case study.enText/Conference Paper1617-5468
