Hi all, I have the impression that the following question was overseen (I should not "answer" a question by another question :-)) I would personally be very glad to see as much ZClass examples as possible, just to see if what I'm doing now is the "right thing". Most interesting would be so see the zclasses used on zope.org:18200 of course :-) (is there a chance to get an export of the Product(s), even if they are not polished). Here is one of my general design questions for zclasses: I will have an folderish "author" class and a special "article" class. To organize the workflow I prefer to have the articles of one author in his "folder", but once finished with them, I prefer to have them in a "issue" folder with the article connected to the author (How?? Several authors are possible (where to put the articles?) Collecting the articles from all the authors each time I want to see the content of one issue gives no sense, this is fixed after pubblishing and will not change and I want something like /issue/1999/10/Zope and not /author/Zope in the overview for the links. Generating it once is the best solution in that case I suppose..). so I have the dichotomy article/author author/article Of course I would have uses SQL in the past (but ZClasses are way cooler and more flexible) and with it you have a connector table, which you should use in this case with Zope to (e.g. ZCatalog)? But the problem remains: where to put the article objects?? My article objects will also travel around from editor to editor. Putting thousends of them in an article folder is also not so good, when you work with them all day.. I have at least 10 other examples, which I am designing right kow, but I feel a litte clueless (kind of OOP-Design question in combination with ZCatalog.) That's why e.g the Zope.org zclasses would help me and other people a lot I suppose, because there you have e.g. the same dichotomy members/How-to How-tos/(from) members connected by ZCatalog, but seeing is better than guessing in that case. KM|net News is at the moment my only livesaver (thanks a lot for it), but more examples would be very welcome. You can have mine to of course (although they will be very special and with German attribute-names!) but there's a long way to go (right now a kind of contact management system is my top project, but I need some advise and ZClasses Zen from the Zope-masters for not designing it in a bad way..) cu and any example welcome... -- Tom
