Merlin-A: A tool to engineer adaptive modelling languages

Modelling languages are pervasive in software engineering to describe systems and processes. They are pivotal in model-driven engineering and low-code development, where automation solutions based on domain-specific languages (DSLs) need to be built for particular domains. However, today's DSLs are rigid, since a single language needs to accommodate a wide variety of users with diverse backgrounds, modelling purposes, and usage scenarios.
