RID, RRN, and RSN
Three constructs that are easy to blur: the RID identifies, an RRN names, and an RSN names a Semantic Space that has an RID of its own.

Identity and naming
One identifier, many names
The RID identifies. An RRN names. An RSN names a Semantic Space.

RID and RRN
A name maps to exactly one RID; an RID may have names over time
Names can be succeeded. The RID never changes and is never reassigned.
Rendering diagram…
Permanent and opaque; compared by exact characters.
Registered and structured; the original stays reserved after a transfer.
RSN
An RSN is an RRN whose kind is exactly space
Not a separate scheme. The space it names is a resource with its own RID.
Rendering diagram…
A space can be renamed, transferred, or moved to new infrastructure. Its RID is what keeps it the same space.
Side by side
Each answers a different question
Kept logically distinct by the specification.
The permanent canonical identity of one referent.
Realm, authority, jurisdiction, space, kind, and local id.
§2.6's fourth question; an RSN names that space, and it has its own RID.
