It is quite easy to create another customized ontology by changing a few terms. The mKR/mKE system (see http://mkrmke.org) has explicit commands for doing this. mKR/mKE is designed to handle many ontologies ("contexts"). Implementing the hierarchy with double-linked lists makes it easy to insert and delete nodes.
