Executable Domain-Specific Modelling Based on Domain Spaces

Domain-specific modelling is used to construct and realise the different application models upon the same specific domain for software reuse. The paper integrates domain-specific modelling and web service techniques with model-driven development, and proposes a unified approach named SODSMI (Service Oriented executable Domain-Specific Modelling and Implementation) to build the executable domain-specific model so as to achieve the target of model-driven development and reuse. The approach is organised by domain space, which is employed as the elementary unit of the domain-specific modelling and implementation framework. It makes software reuse at the domain level, realises the reuse of domain knowledge, and openly extends the range and scale of domain-specific model and its implementation.
