You mean the integrator would subscribe "B" to "event(after, A)" and "AB" to "event(before, B)"? That is near what I am looking for (the individual systems do not know about each other -- only the integrator does). However, I find it more natural to use numbers on a global scale to coordinate the subsystems than explicit tighing systems on one another. If I decide to remove one of the subsystems used as docking point for a different one, then the other systems will no longer be activated. But, probably, this is a matter of preferences. -- Dieter _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
