[Just moving the thread from the archived forums as per a couple of requests]
Taxonomy is a navigation building tool which uses nested sets to control hierarchy. The class used is straight from the CI community (MPTtree) and that does most of the heavy lifting.
Unlike the Pages Module, uri’s are using regular template/url_title paths - so the uri /about/whatever/ could represent something 10+levels deep in the Taxonomy module.
This is an early release, tested in a narrow environment, there will be bugs and some munty code around; I’m using this to learn PHP & CI development so if any devs want to lend a hand - feel free!

Support is available through the GitHub issue tracker.
Feel free to ask questions about what Taxonomy can and can’t do here though.
