yoopus-graph

Let us look at the natural structure of links between people as well as people and documents in every single interest of human knowledge field.
It can be depicted as follows.

Here purple arrow from person A to person B (persons are depicted by smiles) means that person A estimates B as skilled in a field and A is ready to ask an advice from B on any problem in this field.
Arrows from person to document (document is depicted by a roll) means that person think of this document as interesting and useful for him in the same field.
In fact smiles on the picture can represent a single person if they lay on a different layers.
Similary some of the rolls in a different layers can be a single crossdisciplinary document.
So, merging together layers from different fields of interest we will have a graph tthat will be called a yoopus-graph on this wiki.
