Definition: ent last revised by 127.0.0.1 on Aug 17, 2005 4:13 am

The basic data structure of Udanax Gold., It can be thought of as a mutated enfilade, and as a data structure the views of which are virtual enfilades.

To understand ents, you should understand enfilades first, so see EnfiladeTheory.

The new thing the ent does is that you can access it from the bottom or the top to get inverse mappings. (Only now that the two are symmetrical, they're renamed North and South.) That means that nodes can have multiple connections in both North and South directions. Look at EntTheory after reading EnfiladeTheory.

The ent was originally conceived by Eric Drexler (as was at least one Udanax Green enfilade). I don't know whether he invented the Canopy. The ent is named after the "the walking trees with great memory in J.R.R. Tolkien's Lord of the Rings", according to Ted Nelson.
