Outstanding issues (maintain list at http://www.w3.org/2011/prov/wiki/PIL_OWL_Ontology#Outstanding_issues):

  • a. Constraints defined in PROV-DM - distinguish between enforceable constraints and well-formed constraints
  • b. Accounts (and named graphs)+ examples - coordinate between the RDF WG (RDF1.1) and prov WG - make note in PROV-O html document.
  • c. Agents association
  • d. Plan (in place of Recipe)
  • e. wasScheduledAfter - overloaded property
  • f. Start/End of Activity
  • g. onBehalfOf relation between agents and an activity
