ClassificationItemStructure¶
Generalization is Identifiable.
Superclass hierarchy
Definition¶
Complex relation structure for use with statistical classification.
Examples¶
A ClassificationRelationStructure for ISCO-08 would describe each of the major classifications as a parent of its sub-classifications. 1 Managers, for example would be listed as a parent of four sub groups: 11 Chief Executives, Senior Officials and Legislators; 12 Chief Executives, Senior Officials and Legislators; 13 Production and Specialized Services Managers; and 14 Hospitality, Retail and Other Services Managers.
Explanatory notes¶
The ClassificationItemStructure has a set of ClassificationItemRelationships which are basically adjacency lists. A source ClassificationItem has a described relationship to a target list of ClassificationItem. The semantic might be, for example, “parentOf”, or “contains”, etc..
