The following request to introduce a revision workflow to OPS comes from @Minoru_Tanabe.

As an author, I would like to do the following.

  1. After pressing the CreateNewVersion button, press the revision completion button after modifying the items on each form.
  2. At that time, validate the required items.
  3. After clearing all validation checks, the revision is completed and it is automatically notified of the completion of the revision to assigned moderator.

As a moderator, I would like to do the following.

  1. Receive a notification from the author that the revision has been completed.
  2. And then, the moderator check the contents and publish if there is no problem.
