Triple Graph Grammars : Concepts , Extensions , Implementations , and Application Scenarios

Triple Graph Grammars (TGGs) are a technique for defining the correspondence between two different types of models in a declarative way. The power of TGGs comes from the fact that the relation between the two models cannot only be defined, but the definition can be made operational so that one model can be transformed into the other in either direction; even more, TGGs can be used to synchronize and to maintain the correspondence of the two models, even if both of them are changed independently of each other; i. e., TGGs work incrementally.
