I would personally be very glad to see as much 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 (is there a chance to get an export of the Product(s), even if they are not polished).

I understand that the Z Classes we are using (or a set of similar classes) will be made available as a part of the much alluded to, semi-legendary PTK. It seems unlikely to me that the Z Classes we are using will be released before that. I'm afraid I don't know enough to give a useful ETA, but it _IS_ coming, and it _IS_ very slick! <tease tease>

That's why 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.

If I can't actually show you how the Z Classes on Zope.org work, perhaps I can explain what the 'Zope.org way' to tackle your problem would be. On Zope.org, all content (okay, almost all, but forget about that for the moment) is owned by a Member, who is responsible for it. The content is all contained in the folder of the Member who owns it. That means the location is irrelevant to the content-- all our HowTos for instance are scattered willy-nilly throughout our much-appreciated Member's folders, not unlike your author's folders. When you go to /Documentation/How-To, you are shown a list of all the HowTos members have submitted to the Catalog. These HowTos are all still 'physically' located in each of the Membership folders. The Z Catalog allows us to present them all in one place, simply by asking the Z Catalog for everything who's meta_type is HowTo. You could do the same thing for magazine issues: Add an 'issue' property to your article objects, and then add a 'FieldIndex' index called 'issue' to your Z Catalog. Once you have that, you can build a simple Issue object that knows how to ask the Z Catalog for all objects belonging to a given issue, and present them in a nice periodical format. It could even be smart enough to translate the paths you want to use (like my.zine.com/issues/01/02) into a search for items belonging to issue 01, volume 02, or what have you. Hope that sheds a shaft of illumination for you. Mike. -- Mike Pelletier email: mike@digicool.com Mild mannered software developer icq: 7127228 by day, super villain by night. phone: 519-884-2434
