The document presents a reusable decision space for mashup tool design. It analyzes over 60 existing mashup tools to identify 9 key design issues and 27 alternatives. The issues include strategic concerns like target end-users, environmental factors like online collaboration, and technical aspects like interaction techniques and visual languages. The alternatives aim to guide mashup tool designers by classifying heterogeneity and providing a structured set of options.
