A link can be typed by the relationship between nodes, by the structural relationship, by the consistuent roles, or arbitrarily.

The type or explainer for a link helps reader decide whether or not to pursue the link. They are usually graphically distinguished by color, size, icon, or cursor. Color works well. (cbb 6/89)
