*a priori.*We should also not assume that a particular question implies a specific data set. We often can easily get the answer of, for example, the location of each crime. Rarely, however, can we get aggregate data, useful in trend analyses. Perhaps what we need are structured data sets and Wolfram Alpha. In any case, a foundational platform of data is required. In any case, we should be able to formulate a basic question and get a simple answer (on the Web).
