Improving Higher-Order Transformations Support in ATL

In Model-Driven Engineering (MDE), Higher-Order Transformations (HOTs) are model transformations that analyze, produce or manipulate other model transformations. In a published survey we classified them, and showed their usefulness in different MDE scenarios. However, writing HOTs is generally considered a time-consuming and error-prone task, and often results in verbose code.

Here we present an ATL library to facilitate the definition of HOTs in ATL:
