    rdfs:comment """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)"""@en ;
