Query, Views, and Transformations (QVT)
To deliver the two main features of model mappings, construction and synchronization, mappings must be executed automatically. This also shortens turnaround times, scales up to large models, and helps avoid manual work, which results in fewer errors and therefore improves overall quality.
Obviously, the rules that define a mapping have to be provided in a machine-readable manner to make them executable. This requires a formalism in which the rules can be expressed; the models must be formalized too, so that they can be consumed and produced by a machine.
