I have a hierarchical structure something like a directory tree or a nested tree structure:Mammal +-- Ape : +-- Chimpanzee : +-- Gorilla : +-- Human +-- Carnivore : +-- Cat : +-- Tiger Reptile +-- Lizard +-- Snake +-- Cobra +-- Python
Maybe not quite what you asked for, but given the names in the example above I would call this an ontology.
