For learning Zope3, I'd recommend Phillip von Weitershausens book "Web Component Development with Zope 3". Moreover, I find the doctests of the various packages (especially that one of the PAU) very enlightening. > --- NOTE: My view of Zope 3 after only a very few month of experience > with it is following.

You can use the object database outside of Zope 3. ZODB is available as an extra package - even more: Most packages are available as seperate eggs, meaning, that you can integrate them into your Python programs. > Side question: is there an easy way to take small parts of Zope 3, like > for example the schema system to another project without taking the > whole Zope server?

That comes, I think, from the multi platform compatibility. I like the Linux-style config files more, too, but I don't see that much of a difference. > Also read the book of Philipp von Weisenhausen.

My personal critic on the book is that it often does not explain what's happening under the hood, or, more specific, Philipp does it between the lines. Moreover, he concentrates on Zope 3 plus the Rotterdam skin, which I find very limiting and painful. For that reason, I abandoned Rotterdam and now concentrate on the z3c - packages (z3c.pagelet / z3c.form etc.), which are not covered at all in the book, so you don't really know how to do things without Rotterdam, e.g. registering objects, indexing, setting up PAU etc. For that reason, I recommend the doctests of the various packages. > I know Zope 3 is alive and well, but it really seems to me that most of > the communication is going on the source level and it is really hard for > newcomers to get the entry to this wonderful system. True. My impression is, that a lot of excellent people are working on and with Zope3, but most are deeply involved in their projects and have thus limited time to contribute. And people, who do have time, seem to concentrate on other related projects, such as Grok. > Maybe things can be done better.

I think, the most urgent need is the Web page. AFAIK, there are efforts to set up something new, but it's still not ready. Moreover, I read various posts like yours, and quite some documentation fragments over time, but it seems to be hard to unify these efforts. Maybe some central Web page with a Wiki etc., as most projects have, will help.
