Abstract

A growing trend in software construction advocates a change in system modularity. While traditional modules permit easy re-configuration of a system to support different actors, these new modules encapsulate features. These modules better match the language of requirements. As a result, programmers find it easier to design, compose and evolve systems. We have demonstrated, through theory and experiment,that these benefits extend to software verification also. This program now requires work on programming language and environment design and implementation, type systems, interface languages, and more re-fined verification techniques. Our long-term goal is to build on these successes to carry feature-oriented system construction to maturity, through collaboration and cross-pollination between software engineering, programming languages and formal verification.
