Metamodeling Platforms: Observations and Evolutions

Metamodeling platforms are an established foundation for the realization of domain-specific modeling tools in the academic and research domain as well as in the industrial and business domain. This chapter illustrates observations made using metamodeling platforms in industry such as the “democratization of modeling” and the usage of method fragments in Agile Modeling Method Engineering (AMME). In recent years, metamodeling platforms evolved both due to their intensified use in practice and rapid technological developments in services they use. An enhanced meta-modeling platform architecture is presented, incorporating the notion of service-orientation. It is proposed to extend method engineering to method operation, introducing the Continuous Modeling Method Operation approach (CMMO). To combine the expressiveness of domain-specific languages (DSL) and the power of large language models (LLM), a system architecture and integration proposal is presented.
