A visualization concept called "layering" promises to deal with large software systems, but has to date been exclusively oriented towards the level of concrete code rather than more design-level information. The first step in further progress is to derive with some degree of formalism a space of abstract program constructs that can be viewed by layers. Next, iconography for the elements of the space is derived with a similar formal spirit. Finally, the implementation not only allows simultaneous, linked views of concrete and abstract layers, but can also be extended to accommodate any number of subsequent higher- level design views that may be envisaged.
