Please note: The ontology metrics displayed by BioPortal are incorrect as of 7/23/2011. If you need accurate number you will need to compute them on your own, until further notice. In particular these metrics do not distinguish IAO-developed terms versus terms imported from other ontologies, and do not count existing author or definition annotations
