Two elements of ontologies are not present in standard Drupal taxonomy.
One is that objects be able to have attributes (including relationships with other objects). Objects are also called instances or individuals and are clearly nodes. Attributes can be satisfied with CCK (and for relationships, nodereference).
The second element an ontology should have multiple classes, also called concepts. This is probably best approximated by multiple vocabularies, or perhaps a single hierarchical vocabulary which allows multiple parents.
