Specifies data provenance properties for a particular data feed (source), such as resource. TODO actually it's more powerful as it allows to specify other metadata items as well; consider renaming

Item Summary
Name	Type	Multiplicity	Description

Items
- originRef
  
  Flags: RAM
  
  Multiplicity: [0,1]
  
  Reference to the origin object. This object represents the business-wise origin of the data.
- acquisitionItemPopulator
  
  Flags: RAM,runtime
  
  Multiplicity: [0,-1]
  
  Custom population of acquisition items. Path in the populator is rooted at provenance/acquisition container in the metadata. (In the future the path will be allowed to be empty i.e. the populator can provide a value for the whole acquisition.)
- metadataItemPopulator
  
  Flags: RAM,runtime
  
  Multiplicity: [0,-1]
  
  Custom population of metadata items. Path in the populator is rooted at metadata container value. (In the future the path will be allowed to be empty i.e. the populator can provide a value for the whole metadata.)
- useBuiltinPopulators
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Should we use built-in populators for originRef, resourceRef, actorRef, and timestamp? true = always, false = never, null = only if populator returns no value
