RE: [Zope] RE: Workflow and document management system in Zope
This may be the link you were thinking of: http://www.omg.org/technology/documents/formal/corba_business_specifications _av2.htm with the Corba Workflow Specification available as a .PDF.
Thanks for the interesting URLs on workflow discussions.
Corba Ecommerce has very interesting and thorough models of workflows, including UML diagrams and even an XML format for defining state machines. Sorry, this may be old news as I don't have time to follow up the actual threads beyond the first messages.
But if not, anyone designing such a system for Zope *must* study the Corba stuff.
Email me direct if the URLs haven't been published in the discussions and I'll be happy to dig them up (hard to find within www.omg.org). Or, (easier for me), I can email the (large) .pdf files direct.
I also know that WfMC (Workflow Management Coalition, www.wfmc.org) has adopted many of OMG's workflow concepts in the past. I am not sure if what you are referring to is recent new development by OMG.
For a diagram of WfMC's workflow reference model see the diagrams at:
[Jerry] This may be the link you were thinking of: http://www.omg.org/technology/documents/formal/corba_business_specifications _av2.htm with the Corba Workflow Specification available as a .PDF. [AlbertL] Yes. The Task and Session spec there is also very relevant. The Workflow Spec is based directly on the work done by the Workflow Management Coalition mentioned by Albert Boulanger. I haven't checked the original (1993) from the coalition but the Corba document is more modern (1.20, April 2000) with UML diagrams as well as IDL and diagrams similar to those on Albert Boulanger's web page. However I am also referring to the "Corba Electronic Commerce Domain Specifications" 1.0 which I don't think is listed among omg formal published documents yet. This extends to concepts such as "Community", "Membership", "Collaboration" and "Voting" which I think are highly relevant to PTK. Plus detailed elaboration of state machine triggers and transitions etc and more specifically ecommerce related stuff on negotiations and contractual obligations. The related "Negotiation Facility" is listed at: http://www.omg.org/technology/documents/recent/corba_e-commerce.htm and also worth a look. But the one I particularly recommend isn't even listed on their home page: http://www.omg.org/homepages/ecdtf/index.htm Had a good look now, but I'm afraid I've lost the URL for it. Can email a copy (1MB). I was also referring to the "OSM Digital Product Architecture", 20 November 2000, which has the XML state machines spec. http://home.osm.net/supporting/index.html http://home.osm.net/supporting/DPA.0011B.pdf Strongly recommend close study of all of these. (A lot has happened since 1993 ;-)
