How is the CIA's analytical organization organized from a taxonomy point of view?

How is the CIA's analytical organization organized from a taxonomy point of view? In other words, I assume they have the Asia desk and the EMEA desk or whatever, and within those there are specialists in certain countries. But then there may be other specialists that focus on things that are more horizontal in nature, like terrorism or natural resources or something along those lines. I'm curious to learn how they scaffold all of this, both organizationally and from a data point of view. They must have a current file on Uzbekistan, for example. How is that file maintained? What's in it? Where does it source from? How is it updated? How is it revised with accurate information that replaces what was inaccurate information, etc.?
