[kepler-dev] Duplications of actors when searching the actor tree

I understand an actor can be classified under multiple concepts, say a GIS
actor and an output actor. But an output GIS actor can not be an input GIS
actor. Am I wrong here?

It's not a bug, it's a feature.  An actor can be classified under 
multiple concepts ... It might be a bug in the ontology, e.g., it may 
not be the case that all GIS actors are both external input actors and 
output actors.   But this is definately a feature of the actor searching 
-- supporting mutliple conceptual access paths to the same actor.
