What is the overall Buddhist taxonomy?

Building from this question , I'd be really interested in seeing an overall view of the Buddhist taxonomical system. I don't mean the actual names "Therevada", "Mahayana" and so on, or "Soto", "Rinzai" etc. I mean, what is the overall system into which those names fit. In other words, what is meant by words like: school, sect, lineage, vehicle, branch, tradition, and so on. I doubt there will be anything as robust as you'd see here , but a rough guide would be nice.
