   i haven't had time to read through the links, although i will once i get
   some more of that mystical free time stuff, but i wanted to clarify
   about PTK workflows. most of the existing workflow structs in PTK were
   doc based with simple workflows, but there has been a concerted effort
   to refactor PTK into Singleton objects which give abilities to all
   objects vs. the old method of inheritance for abilities. In this
   scenario workflow objects can be plugged into the architecture. Another
   item that gives support for complex workflows is the
   event/subscriber/publisher system being developed right now. check out
   the later half of the PTK archives for August to get some more
   background. if you want to influence the project, now is the time, make
   your voice/needs heard.


Here are two useful diagrams from WFMC's white
paper, "Workflow and Internet: Catalysts for Radical Change" (
http://www.aiim.org/wfmc/finalwp.pdf ). The first is a diagram of
WFMC's reference model. The second is a diagram of workflow concepts.
