 ## Criteria for Review
 
-An ontology that has not been used by other than the developer(s) is not
-yet ready for review. To pass review, the ontology developers must demonstrate at least three
-external users specified within. External users are defined either as researchers not
-significantly overlapping in personnel with the developers or three
-independent groups with three independent artefacts (db, etc) that use
-the ontology.
+Ontology developers must demonstrate at least three external users specified within the metadata file. External users are defined either as researchers not
+significantly overlapping in personnel with the developers or three independent groups with three independent artefacts (db, etc) that use
+the ontology. Note that new ontologies are not expected to have a plurality of users, and thus the automatic evaluation of this criterion can be ignored.
