No problem - can do. Might be useful to discuss use cases at a general level as well hence this thread. Are we moving towards a use case having the structure (quick draft): Description/Context: Audience: (e.g. application, user, toolkit developers, ....) Value/Why: Implications: Technical discussion Other: General notes - to ensure they don't get lost. The structure can't be too long and I think each section must be completed for all use cases (that is, no sections that work for only half of the UCs - hard to evaulate systematically later). Any one what to add/refine/alter etc this list? What experience is there of using these?
