Depending on how the constraints are specified, different options are possible for the transformation rules. If the constraints are part of the requirements model, a model-to-model transformation can be used. In such a base, tools such as QVT [OMG, 2005] can be used. QVT uses Queries on the source models to Transform them into target models, the Views. Part of the views can be pre-specified. This feature can be used to include the generic observation model into the transformation. If the constraints are specified textually, a text-to-model transformation has to be performed. In such a case, compiler construction tools such as ANTLR [ANTLR, 2012] are valuable. They can create parsers and interpreters that output a syntax tree that can then be compiled into a model.
