Deciding how to operationalize non-functional requirements (NFR) is a complex task, and several formalisms have been proposed to represent design decisions and their rationale. Unfortunately, these models can become complex (even unreadable) for designs with many alternatives and/or a well-documented rationale, which makes very hard to review and compare rationale. This paper introduces a Semantic Web-based technique to visualize and compare architecture rationale, combining Softgoal Interdependency Graphs (SIGs) with ontologies reified as named graphs. Reuse of rationale is thus facilitated by allowing architects to understand rationale of previous decisions and/or projects, though automated reuse remains unfeasible until extensive automated capture rationale happens. The approach is illustrated with a case study of Contexta, a museum integration project, using Toeska/Review, a Semantic Web-based tool. © 2009 Elsevier Inc. All rights reserved.
