Principles for Modifying an Existing Ontology Term

Moving terms

Terms can be moved as long as the term's new position correctly reflects its relationships to other terms and moving the term does not imply a significant change in the meaning of the term. Terms should not, however, be moved between ontologies; only within the same ontology. If you need to move a term to a different ontology, first obsolete it and then create a new term in the other ontology.
