I'd like to get your attention about ZPatterns, a Zope framework..

The first stable releas of Zope popped up around the 1999,
so Zope is not so "young".

First the bad news: in my own opinion Zope is difficult to understand 
and use, at
least at the first impact and for non-geeks.
Security is good but not strong: you can always install a malicious 
Product (zope name for applications) which dismiss your site ;(
You must know Python.
You must know well how use object oriented db.

The good news:
 - Zope came with a transactional OO DB
 - Zope can scale
 - Zope is documented quite well.


The ZPatterns are a zope app/framwork for decoupling
View, Data Model, Data Aggregation, Data Access (via SQL/OO DB)



In short, ZPatterns add a good number of layers to a webapp.
With ZPatterns you can map different object (for example a wife and a 
supermodel)
into the same DB model, integrating the application in the mid-tier.

Neverless the two app must be build in Zope.

It is not simple to explain, so I will redirect you to

I am exploring this idea, for seeing if it would be possible to think 
and then build
a publishing framework in Squeak, using the ideas of Zope.
Seaside looks impressive for doing this.

Someone has already done something of similar?
What do you think of Zope?

Ciao ciao ;)
