ISO 22745-2:2010(E)

6 Terms relating to concept roles

6.1
superordinate concept

concept which is either a generic concept or a comprehensive concept

[ISO 1087-1:2000, definition 3.2.13]

NOTE   Being superordinate is not an intrinsic property of a concept. Rather, a concept is superordinate with respect to some other concept.

EXAMPLE   The concept of an aircraft cooling turbine is a superordinate concept with respect to the concept of a scroll housing because a scroll housing has a partitive relation with an aircraft cooling turbine.

6.2
subordinate concept

concept which is either a specific concept or a partitive concept

[ISO 1087-1:2000, definition 3.2.14]

NOTE   Being subordinate is not an intrinsic property of a concept. Rather, a concept is subordinate with respect to some other concept.

EXAMPLE   The concept of a scroll housing is a subordinate concept with respect to the concept of an aircraft cooling turbine because a scroll housing has a partitive relation with an aircraft cooling turbine.

6.3
coordinate concept

subordinate concept having the same nearest superordinate concept and same criterion of subdivision as some other concept in a given concept system

[ISO 1087-1:2000, definition 3.2.19]

EXAMPLE   An aircraft cooling turbine is made up of a turbine wheel, a scroll housing and a impeller wheel. A partitive relation exists between aircraft cooling turbine and turbine wheel. A partitive relation exists between aircraft cooling turbine and scroll housing. A partitive relation exists between aircraft cooling turbine and impeller wheel. The concepts turbine wheel, scroll housing and impeller wheel are all coordinate concepts.
