COEVOLUTIVE META-EXECUTION SUPPORT: Towards a Design and Execution Continuum

摘要

Despite its promises, the lack of support for consistent coevolution of models with theirs meta-models and instances prevents a broader adoption of MDE. This article presents a coevolution support for reflective meta-models and their instances tightly integrated into an execution platform. The platform allows stakeholders, developers and final users to define, update and run models and theirs instances concurrently. Design changes are reflected immediately in the running applications, hosted by the platform. Both instances and models are stored in a shared multi-version database that brings persistency, consistency and traceability support. A web-based implementation of the platform validates the approach and sets the foundations for a collaborative integrated development environment that evolves continuously.
