This is the Relative Name (Rn) of an Org object -- the naming property that, combined with its parent's Dn, distinguishes one Org instance from its sibling instances under the same parent. An admin cares about the Rn because it is the local, human-readable piece of the path for an organizational unit (a folder-like division of tenants, business units, or projects) in the UCS Manager org hierarchy, useful when comparing several sibling instances that share the same parent container. For instance, when a UCS host has several Org instances defined, the Rn is what separates "this one" from "that one" without needing the entire Dn string.
