[Zope-dev] RE: [Zope] Re: Workflow and document management system in Zope
hey Albert, In my opinion getting something like this together can not be done in less than 1 year. I'm familiar with workflow systems and very familiar with Zope. The projects you mentioned at the end of your letter are hardly of production value. You are looking at a major development undertaking. As far as EDM- its pure marketechture. A robust workflow management system that integrates into Zope is currently not available. You should determine exactly what you need, what is available, and go from there. There are many systems that say they are "workflow" and do entirely different things( Verve and Vitria are an example ). Again what you are doing is likely to be a major development undertaking. Good Luck! -josh zeidner 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 5 $ 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. I don't think there is such as system polished and ready within 2 weeks. Here are some starting points: use wftk as a basis, the open source workflow toolkit -- http://.vivtek.com/wftk use openflow, a Zope based, but stalled project, http://openflow.sourceforge.net use Chautauqua, an old python based workflow system, http://www.cs.colorado.edu/~carlosm/chautauqua.html use the old UCI Endeavors workflow (java) system at http://www.ics.uci.edu/pub/endeavors/endeavors.html We have not bit the bullet and built anything yet.

[Zope-dev] ANNOUNCE: Zope 2.3.0 beta 2 released
Hello all - Zope 2.3.0 beta 2 is now available. You can download it from Zope.org: http://www.zope.org/Products/Zope/2.3.0b2/ Highlights of the beta 2 release: - Changed the implementation of emergency_user to be backward compatible with the expectations of third-party user folders. All third party user folders should now work with Zope 2.3 without modification. - Zope is now much more tolerant of dependency problems in ZClasses. Some people were experiencing problems porting Products to upgraded Zope sites when their products contained ZClasses derived from base classes in other products (which may or may not have been installed on the new site). Zope is now much smarter about managing and recovering from failed base class dependencies and will re-register broken ZClasses when the missing Product causing the problem is installed. - Fixes for several other (more minor) bugs reported from beta 1 For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: - http://www.zope.org/Products/Zope/2.3.0b2/CHANGES.txt - http://www.zope.org/Products/Zope/2.3.0b2/HISTORY.txt Brian Lloyd[EMAIL PROTECTED] Software Engineer 540.371.6909 Digital Creations http://www.digicool.com ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] How would I keep _v_* attributes from getting thrown away?
Hello all, I am using ZODB along with CORBA to expose peristent objects. Some of my objects have per-connection/session state. The clear example is file-like objects - effectively exposing persistent StringIO objects through CORBA. The issue is that I want multiple clients to be able to read() iterate over the same file-like corba objects. My initial idea is to have a _v_position attribute that is unique for each Connection cache object and maintains the correct position in the StringIO for each session. I obviously wouldn't want this to be a persistent attribute because a spurious commit would put it into the db and mess up any other users iterating through the same object from a different session. A volatile attribute, _v_position, however can be destroyed at any time with a cache cleanup via deactivate() call. How do I maintain volatile, but per connection stable, attributes on persistent objects? I thought about overriding the _p_deactivate() method, but I am also defining the __call_method__() hook and am bound by Bug 1783 that prevents this kind of thing. My thoughts on building this into cPersistent.c after looking through the code is to provide special processing to not remove some special attributes that also don't get saved into the db. Two ideas come to mind for this: 1) define _vs_* as volatile stable that is neither persisted nor clear()ed. This would slow down the deactivate() method though. 2) define _v_stable as a special volatile that doesn't go away. This would be quick processing in deactivate() and could be a dictionary to account for many stable volatile attributes. Thanks for any help, John -- . . . . . . . . . . . . . . . . . . . . . . . .

[Zope-dev] ZPatterns: wanted: alpha testers for RemoteRack
I've written a class called RemoteRack. It works just like a ZPatterns Rack, except that the BTree it uses internally for storing its persistent data can be anywhere else in the ZODB. I'm using it in a FileStorage-based application where I want to have the application's persistent data stored in separate FileStorage data-file than the application objects. This should allow me to upgrade the application to a new version, whilst preserving the application data, by just dropping in a new application FileStorage datafile. I intend to release RemoteRack as part of the next version of DataSkinAddons. However, I'd like a volunteer or two to test it first.

Hmm. You've got me, then. Have you tried taking the Python Method out of
the mix and using the SQL method directly, like this:
WITH QUERY searchBy_Name(name=self.id)
Also, have you tried running Zope with logging ("STUPID_LOG_FILE") enabled?
What gets added to the log when you try to access the object via
bobo_traverse?

What I really want is several independent Zope servers sharing a mounted database (containing shared resources, eg. template files, design elements etc.).
