- to discover abstractions in large software systems, and pass this information on to software engineers for maintenance and reengineering purposes.
The general Rigi graph model, and the supporting graph editor, rigiedit, arose as a result of our early work on algorithms for the analysis, representation, and visualization of software structure. Software structure refers to a collection of artifacts that software engineers use to form mental models when designing, documenting, or analyzing systems. These artifacts include software components such as subsystems, procedures, variables, calls, data accesses, and interfaces; dependencies among components such as client-supplier, composition, and control and data-flow relations; and attributes such as component type, interface size, and interconnection strength.
Currently, the group is focusing on visualization support to aid in the understanding and reverse engineering of legacy systems. This support is embodied in the form of a general Rigi graph model, and realized in an editor called rigiedit. Inherent in the model is the notion of nested subsystems that encapsulate detail, providing high level overviews of software systems. Recent work has generalized both the model and the tool, thus allowing the use of the graph editor in other domains, and user defined extensions to the built-in Rigi Command Library.
