Interpretive signs provide an important tool for enhancing visitor knowledge and understanding during a natural area experience. The Tree Top Walk (TTW) site in Western Australia adopted a minimal approach to interpretive signs to reduce distractions and allow the site to speak for itself.

Program understanding tools manipulate program representations, such as abstract syntax trees, controlflow graphs, or data-flow graphs. This paper deals with the use of visitor combinators to conduct such manipulations. Visitor combinators are an extension of the well-known visitor design pattern. They are small, reusable classes that carry out specific visiting steps. They can be composed in d...

However, as soon as the number of metamodels and visitor implementations start to grow, some of the pattern shortcomings make its usage less convenient. This paper presents how the synergy between the Visitor pattern and MDE has been addressed by two open source project...
