I definitely think Zope 3 can be used to support education. We plan
on developing a number of applications in this area. It seems at
present that universities are focusing on J2EE and .NET, like most
companies. We are also noticing an increasing ability of
universities to do their own development. Traditionally many of the
software applications that universities use have been purchased. We
see an increasing desire to build and customize applications in
house. We also find however that in universities the funding and
resources required to manage a J2EE or a .NET project are not
necessarily there. We believe Zope could fill this role because it
is faster to develop in, and python is fairly easy to learn. We find
that universities tend to have developers who are a bit less
experienced, and this sometimes includes administrators who actually
want to do their own development. J2EE and .NET is not easy to pick
up for the novice. In this area Zope 3 is particularly challenging in
comparison to Zope 2, however there are entry points in Zope 3 with a
minimal amount of TTW development. In this sense I personally feel
strongly that Zope 3 needs to have a greater emphasis on TTW
development so that it can satisfy the needs of the intermediate
developers. However I feel that Zope 3 is such a clean and well
developed platform that more of these tools will show up.

It really depends upon the costs and benefits and the organizations
goals. I always find it better to examine products that exist and
that suit your needs. Zope was developed (as I understand and may
be incorrect) by a professor in Computer Science in order to explain
web development and instruction on application development. Read
about the history of Zope.
Personally, our company prefers not to hire people with Computer
Science training. This is because we find that professors and
university education in this area is more philosophical and a bit out-
dated; students tend to come out with a mindset that says "what's the
most proper way to complete a project?" rather than "How can I get
this done?" J2EE and .NET are similar. In engineering there is the
constant battle between form and function. J2EE and .NET are all
about form. They are very elegant, and fit all the philosophical
models of computer science, and in particular UML. This however is
When engineering the ultimate goal is to come up with a great
solution to some problem. The solution starts as a thought and needs
to be converted into a application. Programming languages that
reduce the barriers between thought and application are preferred.
PHP does this very well for example, however it suffers from
scalability issues because it is all about function and not form
(ditto Perl). In my experience when you use J2EE you spend a lot of
time converting the problem in your head into a J2EE application.
Because it does not directly parallel thought it is prone to error;
when an application fails it is hard to get your head around it and
fix it. As Stephan Richter once told me, Zope strikes a nice
balance between the direct thought to coding present in PHP and the
well thought out form of a J2EE application. I wrote an application
to list automobiles online: it took 2 files/objects in Zope, and 36
in Java. Java can be so abstracted and modular that you spend more
time trying to code than actually solving and implementing the
problem and being productive.
J2EE and .NET are also about marketing. It is important to note that
none of the major providers: Oracle, Sun, or Microsoft use these
technologies in their own core applications. Most of them still use
C/C++. They will use J2EE or .NET for auxiliary applications such as
the Oracle install, but it stops there.

I'm not sure I understand the question on this one. Zope can be used
to provide components in an XML-RPC model, or just about any other;
this is the nature of the content view model of Zope.

I would like to see more TTW development and a great ability to
integrate with SQL relational databases. The power of the Zope
platforms leads me to believe these will be available within a few

One point of view. Hope it helps.
