In this article, Jean-Jacques Dubray questions the belief that code and models are two separate worlds. He presents a unified view of Model Driven Engineering, Architecture and Programming models based on a novel approach to specify execution element semantics in DSLs.
In this interview Joseph Yoder talks about the Adaptive Object Model (AOM) architecture, a software architecture for easily adapting to changing business requirements.
In this talk Glenn Vanderburg discusses what the Ruby community has learned about building DSLs, and shows how to build state-of-the-art DSLs without going overboard.
