Knowledgeware in Digital Project (PowerCopies, UserFeatures, KnowledgePatterns, etc.) provides a framework for capturing design intent and reusing information.

This example borrows heavily from Alan's guide on the GT wiki and some work done with Neil Thelen at Front. Given a catalog of components and a driving wireframe, the pattern "hangs" the components on the wireframe. Any change to the catalog re-instantiates the catalog part and any updates to the wireframe repopulates the elements (including changing the count of instantiated objects). This creates a quick, iterative design environment without having to worry about reinstantiating parts once you've made any changes.
