2. Creating and Revising Registries

Defining a registry involves describing the namespaces to be created, listing an initial set of assignments (if applicable), and documenting guidelines on how future assignments are to be made.

When defining a registry, consider structuring the namespace in such a way that only top-level assignments need to be made with central coordination, and those assignments can delegate lower-level assignments so coordination for them can be distributed. This lessens the burden on IANA for dealing with assignments, and is particularly useful in situations where distributed coordinators have better knowledge of their portion of the namespace and are better suited to handling those assignments.
