For the unique identifier, the frame name is prepended to the name of the FE together with a colon separator, such as HIRING::EMPLOYEE.
these unique FE nodes are further con-nected to their abstract counterparts with an is-a relation (REVENGE::AVENGER is-a AVENGER), which preserves the connectedness of the FE in FrameNet and also provides some connectivity between frames that share the same FE.
