In this thesis, we propose a new domain-specific language (AsyncMDSL) for describing message-based systems in a concise and human-friendly way. AsyncMDSL extends the Microservice DSL (MDSL) language recently proposed by Olaf Zimmermann with patterns and concepts from Hohpe and Woolf’s Enterprise Integration Patterns book and from the open-source initiative AysncAPI. After introducing AsyncMDSL, we describe the design and implementation of an automated converter capable of generating enriched AsyncAPI documents from AsyncMDSL specifications.
