Interface for PROV Derivation association.

PROV-DM Definition for Derivation: A derivation is a transformation of an entity into another, an update of an entity resulting in a new one, or the construction of a new entity based on a pre-existing entity.

The constructor method ProvFactory.newWasDerivedFrom(QualifiedName, QualifiedName, QualifiedName) can be used to create an instance of WasDerivedFrom. The following code snippet creates a new derivation statement, with a type attribute. The instance of derivation is given an identifier myId. 

 QualifiedName myId= ... ;  // some qualified name
 QualifiedName effectId= ... ;  // some qualified name
 QualifiedName causeId= ... ;   // some qualified name
 WasDerivedFrom myWasDerivedFrom=provFactory.newWasDerivedFrom(myId,effectId,causeId)
 myWasDerivedFrom.getType().add(provFactory.newType(Name.PROV_REVISION))
