[kforge-dev] Delete = Hibernate or Purge for Domain Objects

Mon Sep 19 12:41:14 UTC 2005

Previous discussion off-list has tended to the view that we should 
hibernate most things (e.g. users, projects, services, memberships etc) 
rather than purging them when a delete is requested from a user interface

We can do this several ways:
   1. split delete into purge and hibernate
   2. make delete = hibernate and add a purge command
   3. have no purge, just hibernate

It important to define these semantics so that plugins know what to do 
on particular events. The obvious idea would be that hibernate would 
leave all service instance date intact while purge would result in its 
removal.

My preference is for option 2 but eager to hear comments.

Since all of these changes would result in the addition of actions to 
the Domain Model as perhaps the change of plugin interface we should 
decide on this as soon as possible.
