@param load [Boolean]  Whether to load the whole record from the LDP
   server.  OriginalRecord.load is slow, because it results in a network
   request, so this provides the possibility of avoiding it.
   Default: true.

 @param include_invalidated [Boolean] Whether to include entities that
   have been invalidated with prov:invalidatedAtTime.  Default: false
