Scope note: This property identifies the E39 Actor or Actors who assume or have assumed overall curatorial responsibility for an E78 Collection. It does not allow a history of curation to be recorded. This would require use of an Event initiating a curator being responsible for a Collection. Examples: - the Robert Opie Collection (E78) has current or former curator Robert Opie (E39) - the Mikael Heggelund Foslie's coralline red algae Herbarium (E78) has current or former curator Mikael Heggelund Foslie In First Order Logic: P109(x,y) ⊃ E78(x) P109(x,y) ⊃ E39(y) P109(x,y) ⊃ P49(x,y)
