I am very interested in a general, fairly full featured workflow system on top of Zope as opposed to using an external workflow product for a fundamental reason. While one could come up with a way of getting what I need with an external system, it would be messy. I need workflows to be explicit and versioned. We make use of ZODB to version content that end users generate. We don't make use of Zope's versioning but use or own hierarchical version tree which is easy to do in Zope. End users generate new workflows and revisit past workflows. The user sees this versioning as notebook pages using a scientific notebook metaphor. It is much cleaner to use ZODB and ZPublisher to do all this instead of having a version tree in Zope and a bunch of correspondences to outside objects in an external workflow system. Thus, there is a lot of value in having a fairly general workflow system whose representation and publishing uses ZODB and ZPublisher. By the way, if there are other folks interested in such a workflow system let me know. We may just bite the bullet and build one. I have who will do most of the coding in mind. What will be produced is a Zope-based workflow system with a java thin client visual workflow/dataflow editor. Right now I do not have the funding but folks with resources could speak now ;-).
