Service-oriented architectures and microservices have gained much attention in recent years; many companies adopt them in order to increase agility, maintainability, and scalability of their systems. Decomposing an application into multiple independently deployable, appropriately sized services is challenging. With strategic patterns such as Bounded Context and Context Map, Domain-Driven Design (DDD) can support software architects and domain experts during service decomposition. However, existing architecture description languages, methods, and tools do not support strategic DDD sufficiently. As a consequence, different interpretations and opinions regarding pattern applicability can be observed, and it is not always clear how the patterns can be combined. Context modeling is an ad-hoc, error-prone activity.

In this talk, we present Context Mapper, an open source project providing a Domain-Specific Language (DSL) for DDD. Aiming for a clear and concise interpretation of the patterns and their combinations, we distilled a meta-model of the DDD patterns from community input. The DSL provides a light syntax to express the patterns and model DDD context maps. An Eclipse editor supports syntax highlighting, code completion, and model validation. Other tools allow designers to refactor and continuously evolve the models and generate lower-level artifacts such as service contracts. DSL and supporting tools promote iterative, incremental modeling, and agile practices.
