Jon's Radio – Taxonomy Creation and Maintenance. Quote: “These things are, as I said, always trickier than you expect. Content management systems try to make reasonable assumptions about the display of time-ordered and categorized data, but when the relationships between those two evolve, as they inevitably do, assumptions break down. Tools that would make it easier for users to do wholesale recategorization or reordering of data are rarely available, for the very good reason that they are hard to create.” [Serious Instructional Technology]
