modelltillmodelltransformationer

Modelltillmodelltransformationer, often translated as model-to-model transformations, are a core concept in model-driven engineering (MDE) and software development. These transformations involve taking one or more models as input and producing one or more new models as output. The models can represent different aspects of a system, be at different levels of abstraction, or be expressed in different modeling languages. The primary goal is to automate the process of creating or modifying models, thereby reducing manual effort and potential errors.

The input models can be, for example, a high-level domain model and a more detailed platform-specific model. A model-to-model transformation would then bridge the gap between these, generating the platform-specific model from the domain model. Alternatively, transformations can be used for tasks like refactoring models, migrating models between different versions of a modeling language, or generating documentation from models.

Various technologies and languages exist to define and execute model-to-model transformations, such as ATL (Atlas Transformation Language), QVT (Query/View/Transformation), and XSLT (Extensible Stylesheet Language Transformations) when applied to XML-based models. The effectiveness of these transformations relies on precise and unambiguous definitions of both the input and output model structures and the rules governing their relationship. They are a fundamental tool for increasing productivity and ensuring consistency in complex software systems.
