Model transformation with immutable data

Mainstream model transformation tools operate on graph structured models which are described by class-based meta-models. In the traditional grammarware space, transformation tools consume and produce tree structured terms, which are described by some kind of algebraic datatype or grammar. In this paper we explore a functional style of model transformation using Rascal, a meta-programming language, that seamlessly integrates functional programming, flexible static typing, and syntax-based analysis and transformation. We represent metamodels as algebraic data types (ADTs), and models as immutable values conforming to those data types. Our main contributions are (a) REFS a simple encoding and API, to deal with cross references among model elements that are represented as ADTs; (b) a mapping from models to ADTs augmented with REFS; (c) evaluation of our encoding by implementing various well-known model transformations on state machines, meta-models, and activity diagrams. Our approach can be seen as a first step towards making existing techniques and tools from the modelware domain available for reuse within Rascal, and opening up Rascal’s transformation capabilities for use in model driven engineering scenarios.
