Dear Mr boulanger,
Under the suggestion of Jerry, I came to look at your contribution t the zope
mailing list (I am really new at usins and experimenting ZOpe).
I am looking for a workflow (WF) linked to a electronic document management
(EDM) system and a groupware email based (I have just happened to come
accross aethera from the Kompany) that would be free software and preferably
in Zope + Python. The WF+DEM system I am looking for need to be usable with
only a browser (to be independant from the client ... that could be
proprietary !), store its data into a postgresql database. It should be
demonstrablable (at least showable into a proof of concept) within 2 weeks
and be already installable and usable within 2 or 3 months. (I have obtained
taoday that the date when we'll decide on the system would be postponed 2
weeks from wednesday 24/1 to wed 7/2)
If I could find such a marvel, I may find the money to pay for it, at least
50000 $ to start with (this amount is a rapid guess; I may give more precise
amounts we could spend in the following week)
The idea is to use that combination of tools INSTEAD of buying a closed,
proprietary solution (that may exist but be expensive and really har to
parametrize), that NEED to be linked to a SAP ERP system.
All suggestions and ideas are welcome, also on the selection criteria.
(I happen to be responsible for the IT dept of the public institution that
wants to buy such a tool, but be new in the place and do not yet know a lot
about WF and EDM !)
Soon I may be able to give you more details about the requirements.
-- quoted from your mails --
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.

See also the papers and the web-based workflow thesis at:

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 ;-).

Thanks for your interest.
