Correct me if I'm wrong, but the only way I see to do this *inside* the Zope application is to keep all your articles inside one folder (pool) and have key documents in your tree structure which reference an article in the pool. I don't know if problems appear when you establish an acyclic directed graph structure in the object hierarchy itself (I asked the question myself months ago without an answer). I see no point why it shouldn't work, but it is not maintained by the application. An interesting fact is that your object's properties vary when accessed by different paths due to the acquisition structure. An object inside Zope's database (again, correct me, if...) doesn't know about its father. It only knows about its sons, the aq_parent path is constructed on each access. Would also like to hear more about this... Stefan

As a demonstration project to try and get a client to go with Zope, I'm converting a newsfeed database that I had originally built using Perl.
The object of the game is to pull fresh articles from a Reuters server every two hours and put them in a bin. A human editor goes through the bin, culls and sorts the articles, edits where appropriate.
One article may appear in more than one section of the site. For example, an article titled "Zope Is Cool" might appear in the Python, Web Development, and Open Source sections. Each section has its own contents page.
This is where I get confused. My Perl application simply used the filesystem as a database, and generated three separate static copies of "Zope Is Cool", placing one in each of three directories: /python, /web_development, and /open_source. I suspect there are much better ways to do it in Zope, but how do I organize things?
My naive idea is to make each article a Document, one of whose properties is a list (or dictionary) of categories in which it should be placed. Generating each section's contents page would then take some figuring out, and performance on doing the contents page would be a concern.
If there's a better way, I'd certainly appreciate hearing about it.
