Jolie & LEMMA: Model-Driven Engineering and Programming Languages Meet on Microservices

Abstract: In the field of microservices, Model-Driven Engineering has emerged as a powerful methodology for architectural design, and new programming languages have introduced language abstractions to deal with microservice development more effectively. In this article, we present the first preliminary investigation of how the two approaches can be married, taking the LEMMA framework and the Jolie programming language as respective representatives. By developing a conceptual metamodel for Jolie, we elicit a strong link between the two approaches, which shows that there is much to gain. We discuss a few low-hanging fruits that come from our finding and present some interesting future directions that arise from our new viewpoint.
