  ##
  # A behavior that provides methods for working with aggregations
  # (as defined by DPLA::MAP::Aggregation), in the context of entities that
  # are generated by activities.

  class AggregationEntityBehavior < Krikri::EntityBehavior

    ##
    # @param load [Boolean]  Whether to load the whole record from the LDP
    #   server.  DPLA::MAP::Aggregation#get 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

    # @return [Enumerator] DPLA::MAP::Aggregation objects
