The main emphasis of this contribution is the specification and transformation of specification architectures using GenGED. In GenGED, a visual language (VL) is defined by a visual alphabet and a visual syntax grammar. We define a VL for specification architectures by composing VLs for graphs and Petri nets enhanced by Petri net morphisms. From this VL definition a syntax-directed editor is generated supporting the editing of consistent specification architectures where local and global changes can easily be defined as transformation rules in our VL and visualized in the GenGED environment.
