Typed relationships

The About page counts 12,854 typed relationships. Each is one directed edge in the encyclopedia's mixed graph of prime and domain-specific abstractions: a child, a parent, the kind of relation between them, and a written reason. The hierarchy, sunburst and force graph views are three renderings of this one graph.

conditional 205

A strict edge holds without exception; a typical one holds in the usual case; a conditional one names, in its reason, the condition under which it holds. Every edge's reason is shown on the pages it connects.
