ClassificationItem¶
Superclass hierarchy
Definition¶
Placeholder for a category within a statistical classification.
Examples¶
In the 2012 NAICS (North American Industry Classification System) one Classification Item has the Category construction, and has the Code 23, which designates construction in NAICS.
Explanatory notes¶
A Classification Item defines the content and the borders of the Category. A Unit can be classified to one and only one item at each Level of a Statistical Classification. As such a Classification Item is a placeholder for a position in a StatisitcalClassification. It contains a Designation, for which Code is a kind; a Category; and other things.
This differentiates it from Code which is a kind of Designation, in particular it is an alphanumeric string assigned to stand in place of a category. For example, the letter M might stand for the category Male in the CodeList called Gender.
Statistical Classificatinos often have multiple “levels”. A level is defined as a set of Classification Items each the same number of relationships from the top or root Classification Item.
