QVT Relations Language (QVT-RL)

QVT Relations Language (QVT-RL) is a formal language used to define how different models or representations of the same data relate and transform to each other within model-driven engineering. It specifies rules and relationships that ensure consistency and correctness when converting models, enabling automated and reliable model transformations. Think of it as a precise set of instructions that guide how one structured data set is mapped or adapted into another, maintaining intended connections and properties across different system designs.
