From people's comments, here and on the archetypes mailing list, I am
pretty convinced that there is support for a through the web editing
environment, even from Alexander Limi, expert on human interfaces and
co-author of Plone.
You have an incredibly annoying tendency to take the words of someone
"important", drop their name and qualify their "importance" and then
bend their statements to fit your point of view. Alex co-founded Plone,
and I'm sure he likes being referred to as an expert on HCI, but he
didn't exactly say that the path you're going down has much merit either.
What there seems to be support for, is that in a CMS like Plone,
administrators may have a need to define schemata (as in - I want these
fields with these labels and this validation) for content types, in
order to capture domain-specific information. That is, within the
high-level UI constructs which Plone affords all content.
There does not seem to be very much support for building complex
systems, with significant amounts of custom logic TTW. By all means,
knock yourself out, but at least try to weigh the arguments that are
As for grok contexts, you are arguing about a blade of grass. Look at
I would like to be able to build a complete app, a network of objects
persisted on the the ZODB, with a couple of clicks.
Grok (or Archetypes in Plone) would allow you to build that in a couple
of lines of code, and ArchGenXML (with Archetypes/Plone) in a couple of
clicks in ArgoUML.
Why am I not going with Zope3? It seems like way too much overhead.
But most importantly it does not give me the stuff I am really looking
for. Sure it does some schema stuff, but that is mostly for 1 object
and its user interface, rather than over the whole network of objects.
Why are there schemas for the user interfaces, and interfaces for the
other interfaces? Lack of symmetry. Zope3 checks that the next object
in the network has the right interface. That is too complex for me. I
just want to say that a person can have a role hiring manager, a role
candidate, a role recruiter, or a role accountant. So Zope 3 does not
provide the abstraction that I am looking for. Which leaves me with
Zope 2. And I am back to building up my own desired abstractions on Zope
I'd contend that you possibly haven't quite understood how these things
would work in Zope 3, and if you are going to build your own
abstractions anyway, you will probably find it *way* easier to do that
on top of Zope 3's primitives than Zope 2's. I've been developing on top
of Zope 2 (with Plone) for a long time, and I still find things like
product factories and dispatchers and the security model confusing. By
contrast, the ones in Zope 3 are better documented and burdened by a lot
Zope 2 still has a lot going for it, and is evolving and growing and I
still love it, but if you're about to set out building some new
development tool, and you don't already understand the low level of what
you're about to try to plug into, you'll probably find it much easier to
start with a copy of Web Component Development with Zope 3
(worldcookery.com) and Zope 3.
