Introduction to the AAT
revised May 2019 For educational purposes
The
hierarchy
in the AAT refers to the method of
structuring and displaying the concepts within their broader contexts
Concepts in the AAT typically have a genus/species relationship (rather than whole/part relationship)
Hierarchies are built by using the Parent_ID, which is linked to each Subject_ID; the Parent_ID is hidden from end-users
For end-users, the Hierarchical Position is typically indicated in a display that shows broader contexts or
parents
of the concept, e.g., genus/species
relationships indicated with indentation
