https://doi.org/10.1007/978-3-319-04403-3e models are complicated and hard to build. The goal of generic model management is to reduce the cost of developing such applications by raising the level of abstraction of model manipulation operations.

4. State-Based Semanticsd problems. Using Rondo, we developed scripts for several practically relevant scenarios, such as change propagation, view reuse, and reintegration. We found that the scripts produce intuitively correct results and that the structural operator definitions that we give are useful for solving practical problems.

5. Change Propagation Scenariotness of our solution by examining several special cases and by showing that the scripts that we developed match the intuition in these special cases. We cannot formally prove that our solution is correct.

6. State-Based Semantics in Rondo Chap. 4. To avoid ambiguity, we refer to the operators and scripts used in Rondo (Chap. 2) as structural and to those of Chap. 4 as state-based. The discussion that we present illustrates how the behavior of Rondo and other complex metadata management systems can be analyzed in terms of state-based semantics.
