Thank you for your feedback, Rik!
I wonder whether the parts about inheritance weren't too difficult for someone without any knowledge of the subject.
Yes, I agree. But I wanted to try to put something together that was smaller than a book. Plus, if someone has absolutely no background in OOP, then Zope will be hopelessly beyond them. (Try explaining a DTML command like <dtml-let item="_.getitem('sequence-item', 0)"> to a person who doesn't understand namespaces.)
Ha, try explaining some of the more esoteric constructs to someone who does :-\
My purpose was to provide a summary for people like myself, who aren't programmers by trade, but who have gleaned a few programming concept over the years. I read the term "attribute" and I think I know what it means, but then I see the term "property" a few sentences later, and I am not sure if the two terms are equivalent. The process of writing helps me make such distinctions clear for myself. If I'm fortunate, it will help others, as well.
OK, understood.
Moreover the relation with acquisition does not come to be completely clear:
Tell me more! I want to know how to improve the descriptions so that they are crystal clear.
Hm, I'll have to look that over again.
Once again, the part about the working of acquisition itself is great.
I'm blushing...
One more remark: in the example, you take three folder objects at the same level as the basis for acquisition. While this is no problem in the example shown, in practice acquisition will act to do unexpected (at least for many users, not from design perspective) things if you use it on sibling folders.
Once again, tell me more! What kind of unexpected things happen? And in what kind of situations is acquisition useful? Now that I understand how it works, I can make Zope do what I want (kind of). But why is this better than the old "one path, one result" system?
Perhaps my drafts for ZBook called "changing context in Zope" may help you a bit further (haven't got around to the sibling folders and acquisition part though, perhaps later this week). I have made them available at my Member pages @ zope.org: http://www.zope.org/Members/Hoekstra/ChangingContexts1 for easy reference, awaiting further publication. Rik
