Definition: 

This relationship describes the levels within a hierarchical structure. It allows for strict ordering of the hierarchy, optionally relating a concept to the level, and identification of the relationships within the level. This allows clear identification of all relationships making up a hierarchical collection. When the member of a level is defined as an OrderedRelation, the source target of each member is considered to be a member of the level.

Example: 
A collection of industries may have a first level of the following relationships (source: Manufacturing target: unordered set of manufacturing industries), (source: Construction target: unordered set of construction industries), etc. where Manufacturing and Construction are members of Level 1.
