I'm kind of surprised not to see "good data is accurate" as an item in its own right.<p>You could argue that accuracy is part of "contextual" (the context of data includes the error bars on its measurement), or part of "useful" (inaccurate data are not useful), or part of "valuable" (inaccurate data has less financial or social value).<p>Still, I would say if "semantically correct" gets its own item, then "factually correct" deserves to be made explicit as well.
