Declarative Metaprogramming to Support Reuse in Vertical Markets

To eliminate the difficulties caused by the implicit nature of the natural relationship between domain models (and the corresponding delta-analyses) and framework instances, we aim to provide a mechanism for the construction of a bidirectional, concrete, active link between domain models and framework code by constructing a new instance of declarative metaprogramming. This instance supports a symbiosis between a prototype-based, framebased knowledge representation language and an object-oriented programming language. This implies that framework code in the object-oriented language co-evolves with the corresponding knowledge representation. Representing domain-dependent concepts in the same knowledge representation allows us to transform delta-analyses into framework reuse plans, and to translate changes in the framework code into domain knowledge adaptations, at a prototypebased and frame-based level.
