      ISSUE-500 (activity hierarchy)

  * Original
    email:http://lists.w3.org/Archives/Public/public-prov-wg/2012Sep/0090.html

  * Group Response
      o This issue is a follow-on to issueISSUE-447 (subactivity)
        <http://www.w3.org/2011/prov/wiki/ResponsesToPublicComments#ISSUE-447_.28subactivity.29>
      o The working group has decided that it would not specify a
        "subactivity" relationship between activities.
      o Therefore this suggestion will not be adopted.
  * Proposed changes: none
  * References:
      o See
        issue-447:http://www.w3.org/2011/prov/wiki/ResponsesToPublicComments#ISSUE-447_.28subactivity.29
