ADU (beta): Universe Data Tree

The tree is one of the most frequently used structures to organize information. Even if the tree is not visible, the clumping of elements into groups and subgroups shows up in all kinds of environments. The need to classify is embedded in our way of thinking.

ADU (beta) is an attempt to concentrate all the data that surround us in a single tree. Through this page you can add information to the tree and view what others have already added.
