Get Item¶

  // The identifier is set and recognized by the source.
  // It is possible but unlikely that two items coming from two different sources will have the same id.
  //
  // The rdb source sets the id to a UUID.
  // The commands source sets the id to the command id

  // If this item time specification is relative to another item, ``relativeTime``
  // contains a reference to that item as well as the relative start (the duration

  // ``relativeTime`` before sending the item to the client.
