RSN
RSM Space Name
A specialized RRN, of kind “space”, that identifies a Semantic Space.

An RSN is not a separate naming scheme. It is an ordinary RRN whose kind segment is exactly space, used to name a Semantic Space — a governed knowledge environment such as RSM, Wellzai, or Musewoods. Because a Semantic Space is itself a resource, it also has its own RID, and registering a space binds its RSN to that distinct space RID under verified authority.
The RSN gives the space a readable, structured name; the RID gives it permanent identity. A resource's Identity Record can then point to its authoritative space by both, so that readers see the name and machines rely on the identifier.
Example
rrn:451:451labs:us-ca:wellzai:space/root names the Wellzai Semantic Space, whose illustrative RID is 451.SD27J6QHDVEF0DYY. You can resolve that RSN in the demonstration: it maps to the space's RID first, then shows the space's own record.
A common misconception
“The RSN names the server that runs the space.” It names the governed logical space, not its current Locus process, database, container, or hostname. The deployment can move, and the space remains the same space with the same RSN and RID. Note also that spaces or workspace would not make an RRN an RSN: the kind must be exactly space.

Every RSN is an RRN. It names a Semantic Space. Why a space needs both a name and an RID is the subject of a Fieldnote.
