<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I know I’ve asked this before, but I still have to
question whether Zope 3 is ready for a production environment. I REALLY do not
wish to be difficult, and I love the concept of Zope 3. I think it may be the
greatest thing since Linux. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The documentation is not well defined, which makes
deployment dangerous because one may produce an application that does not conform
to future releases of Zope. Configuration is done through a series of
configuration files, which are easily broken and difficult to traverse. If the
configuration is damaged in someway through a mistake or other reason, the
server will not restart until it is fixed, which presents serious challenges in
a production environment – in the heat of the moment, wading through
errors is not trivial, especially for the non-Zope experienced system admin who
will be on call at 2:00 AM. The errors are difficult to comprehend and do not
easily point out where problems lie. Once problems are found it is difficult to
understand what they mean. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I can only find one semi real-world Zope 3 example (the SIP
application), and it does not even run under Zope 3.2; while I’ve been
able to wade through and fix many errors, I continue to get more as the
interfaces and standards keep changing. Even the current i18n facility does not
seem to work properly, editing messages frequently gives errors and does not
update properly. Errors in general seem to give unexplainable results.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I do see many advantages to Zope 3 and I am willing to
tolerate a lot because of those advantages, but it seems like it not quite
polished yet, and there may be some architectural issues that are problematic
for real-world use. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

it been relatively bug-free? Has it integrated with an RDBMS?<o:p></o:p></span></font></p>
