In terms of the discipline of Information Organization (think "library
science", if you like), is-part-of-1 would be a "topic-subtopic"
classification in some subject language.  Another important kind of (pseudo)
hierarchical classification is "topic-perspective".  For example, you can
view "dog" from the point of view of health, training, work abilities,
psychology, evolution, color sensing abilities, etc.
