hierarchical naming
Lotus Domino
A system of naming associated with IBM® Lotus® Notes® IDs that reflects the relationship of names to the certifiers in an organization. Hierarchical naming helps distinguish users with the same common name for added security and allows for decentralized management of certification. The format of a hierarchical name is: common name/organizational unit/organization/country code -- for example, Pam Tort/Fargo/Acme/CA.
