Every entity in a petname system may act as its own namespace, providing "paths" to names to other entities in the system as a graph, and these provided names are called "edge names". For example, "example.org" is an edge name in "dns ⇒ example.org", and "Sarah Smith" is an edge name in "Uncle Bob ⇒ Sarah Smith".1 We don't have to get rid of popular naming systems like DNS, but can absorb them in such a way that they are on equal footing with any other entity.
