Scenarios are narratives that illustrate future possibilities, such as proposed systems or plans, and help policy makers and designers choose among alternative courses of action. In view of the decision-making uses to which scenarios are put, it would be valuable to elaborate scenarios at multiple levels of detail or to substitute detailed eventualities by starting from a common core of narrative episodes and refining them differently. Although domain-specific techniques and computational environments exist for encoding simulating and manipulating scenarios, there exist no general-purpose scenario representations between the extremes of formality and informality provided by executable simulation programs at one extreme and free-form text or streaming media descriptions at the other. The challenge is to define a representation for scenarios that supports a wide range of discussion and comprehension activities while remaining independent of content and access mechanisms. Our approach is...
