The PROMPT Tab - merging classes
After a user follows one of PROMPT's suggestionmerge the Ontology class from the UPML ontology and the OntologyFrame class from the MDLang ontologyPROMPT creates a new class Ontology in the merged ontology which has the slots of both of the original classes attached to it:

PROMPT also creates a list of conflicts: there are frames which referenced as allowed classes for slots and that are not on the ontology. The list of suggestions also changes to include new suggestions (for example, merge-slots for the two axiom slots)
