Poster: ArchDiff - Architectural Differencing and Merging

Student: Christopher Van der Westhuizen

Advisor: André van der Hoek

Abstract: ArchDiff helps an architect in understanding and propagating changes among different architectures. Specifically, ArchDiff uses an architecture-based differencing algorithm with which a developer can easily and quickly understand the difference between two architectures in terms of sets of components, connectors, and links that have been added, replaced, and removed. ArchDiff is completed by ArchMerge, a tool that can propagate a difference between two architectures to a third architecture, in effect automating the process of updating one architecture with functionality from other architectures. ArchDiff and ArchMerge are implemented on top of the xADL 2.0 architecture description language and are used by the Ménage environment for managing evolving product family architecture.
