- One of the shortcoming of current (meta-)modelling tools is their strong reliance on their implementation level.
- While it does offer its benefits, certainly for tool developers, it seriously impedes portability of models.
- Model management operations are handcoded in the implementation language of the tool, making it difficult for users to grasp their semantics.
- Furthermore, model management operations themselves have strong reliance on the internal data structures used by the tool, making comparison of algorithms, even at a conceptual level, difficult.
- In this paper, we analyze the reasons and effects for this strong reliance on the implementation level.
- We offer a solution which allows the explicit modelling of model management operations in a strict metamodelling framework.
- Even those operations that require access to multiple levels in the modelling hierarchy are supported.
- To aid in this effort, we furthermore break the strong link between model management operations and the data structures in use by the (meta-)modelling tool.
- Our technique is illustrated through the explicit modelling of a retyping operation on a petri net.
