Product development will get much simpler with Zope3 technology

In about 2 to 4 years, we may have new ZClass like

And I am quite confident that the old ZClasses will live til
Note that I prototyped such functionality a couple years ago. One could create
TTW (Persistent) schemas and then declare a Content Component Definition
based on this schema. People could then create instances of those content
components. The Content Component Definition utility took care of doing all
the security and basic menu/view setup. One can then write views and adapters
for the content component to give it functionality.
Unfortunately, persistent schemas got broken at some point, so the code is not
that useful anymore. I really need to get together with Jim and force him to
fix the problem with me, since I constantly forget what the problem is. ;-)
I'll need to work on persistent schemas very soon. Could someone recap
what the problem is ? ISTR that there was a problem with the way the are
cached by the interface machinery, and maybe a pickling problem. Does
someone have a bit more details (without going into great lengths, I'll
be looking at it in any case).
Your recollection is more or less correct. We can't currently directly
a persistent interface. If someone wants to get into the details and work
on this, I'd be happy to provide advice.
