I created a handy little tool which can be used to grab taxonomy information. You can download the tool here. This is an Excel spreadsheet which has some macros.
The tool connects together lots of different sets of taxonomies which it will then load into either a tree view so you can look at the taxonomy or you can load the taxonomy information into the Excel spreadsheet.
These are the lists of taxonomies which the application points to:
This is just experimentation. The primary point I am trying to make is why have only one list of taxonomies when you could have many, many different lists which serve different purposes.
This application can be reverse engineered and modified to your heart's content. If you do fiddle with it and you create some interesting modified version of this, please send me a copy so I can check out your handy work.
