The are some workflow implementations for Zope

• zope.wfmc ( http://svn.zope.org/zope.wfmc)
• Alphaflow ( http://www.gocept.com/gocept-de/aktivitaeten/innovation/alphaflow)
• zope.workflow ( http://svn.zope.org/zope.app.workflow)
• Openflow ( http://www.openflow.it/EN/index_html)
• hurry workflow ( http://codespeak.net/svn/z3/hurry/trunk/)
• eventworkflow( http://svn.zope.org/eventworkflow)

For ict-ok.org zope.wfmc with xpdl-files are used. A simple example can be found here:

• XPDL-Code: source:trunk/org/ict_ok/components/host/wf/host_nagios_clean.xpdl

some different workflow types

• activity based
  • means that the processes are changed by activities,
    ( http://www.openflow.it/Documentation/documentation/OpenFlowIntroduction)
• content oriented
  • the content object is in the center of the workflow process
