    - #### getEffectiveUpdatePolicy

          String getEffectiveUpdatePolicy(RepositorySystemSession session,
                                        String policy1,
                                        String policy2)

      Returns the policy with the shorter update interval.

      Returns:
        The policy with the shorter update interval.

    - #### isUpdatedRequired

          boolean isUpdatedRequired(RepositorySystemSession session,

                                  String policy)

      Determines whether the specified modification timestamp satisfies the freshness constraint expressed by the given update policy.
      Parameters:
