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.

Removing asserted subclasses that are also inferred

  • Asserted is_a parents do not need to be retained as SubClass of if the logical definition for a term results in their inference.
  • After creating the new term, you should synchronize the Reasoner. This will show see the reasoned classification of the new term, including inferred subclass(es).
  • If the logical definition is redundant with the asserted subclasses, those can be deleted by clicking on the X to the right term in the Description window in Protege.
  • If the inferred classification does not contain the correct parentage or is inconsistent, the logical definition should be modified.
  • Make sure to run the Reasoner after each change and verify that all inferences are correct.
