A microservice reference case study for design-runtime interaction in MDE

Model-Driven Engineering techniques may achieve major support to the software development of nowadays complex systems when they allow managing relationships between a running system and its design models. These relationships can be exploited for different goals, such as the software evolution due to new functional requirements. In order to address this challenge, researchers need to better understand the nature of the available runtime information and related correspondences as well as how leveraging such knowledge. Typically, to this end, they rely on reference applications. In this paper, we present a reference case study for design-runtime interaction in MDE. It is based on Train Ticket, a microservice-based web application, and its monitoring infrastructure. Also, the case study provides its software modeling artifacts designed in UML, a dataset of monitoring logs, and the definition of design-runtime correspondence as traceability links. We invite researchers to consider this case study as a reference for extending or new contribution to this topic.
