This paper illustrates the techniques and consideration related to the implementation of the Visual Modeling and Transformation System focusing the implementation of the core functionality called AGSI. Graph rewriting and theoretical achievements are outlined, then architectural decisions, and detailed design trade-offs are presented. The algorithmic solutions have a special emphasis; the metamodel-related techniques are elaborated and illustrated with pseudo code.
