Level

Identifiable position to which codes in a scheme of codes are related.

In a "level based" hierarchy the Level describes a group of Codes which are characterised by homogeneous coding, and where the parent of each Code in the group is at the same higher level of the Hierarchy.

In a "value based" hierarchy the Level describes information about the Hierarchical Codes at the specified nesting Level.

A Statistical Classification has a structure which is composed of one or several Levels. A Level often is associated with a Concept, which defines it. A linear classification has only one Level.
