Applying Domain-Specific Languages in Evolving Product Lines

Abstract

This demonstration shows how domain-specific languages for modeling and generating variant products can evolve together with the product line. In the demonstration, examples from practice are illustrated and executed, covering both domain engineering and application engineering. The examples cover the typical evolution scenarios: adding new features and variability points to a product line and then to existing products, changing their variation, and removing them completely from the product line. The evolution of the domain-specific languages, and the versioning of both the languages and products built with the languages, are demonstrated.
