I can't give you any feedback on python's suitability for building expert systems, but I can say that Python is *not* a scripting language. It happens to be very useful for that, but it is a real, full blown, sophisticated, Object Oriented programming language. It is, however, primarily an *interpreted* language rather than a compiled one, though you can optimize around that with the appropriate use of modules written in C or C glue code calling modules written in other compiled languages. If you already have an expert system in Eiffel or some other compiled language, then taking advantage of Python's facility for acting as a glue language would make a lot of sense... --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] KeyError in UnIndex
Hi guys, I've got an issue here, the following traceback can be seen after several users modify and view the same object in a short (2-3) minute period. I've tried recataloging the objects but that doesn't help either; this error is seen every time.. Site Error An error was encountered while publishing this resource.

Re: [Zope-dev] WebDAVLocks lost in Control_Panel (was:: [ZPT] how to unlock a webdav locked element ????)
I suspect this is a bug. I thinmk it is due to upgrading your data.fs from an earlier version of Zope. At some point in time Control_Panel has been created as a object in data.fs, and this object has an _objects tuple that contains the objects from 2.2 or more likely 2.3... I have this at work, where the same data.fs has been upgraded from 2.1.x to 2.4 and I had to manually remove the Control_Panel instance's _objects tuple, then everything worked fine. I do not see this at home where I have a fresh 2.4.1 install.

The CVS contains a fixed version for this problem.

[Zope-dev] Stripogram or similar in core
What do people (especially Chris) think of making ChrisW's stripogram part of the core of Zope. Just discussing this with some colleagues today and we got onto a marshalling data and it occured to us it would be nice to do something like input type=text name=something:html:p:br that would only allow p and br in the html. Ok, its easy to get around with a fake form, but how about being able to only specify certain html tags in metadata in the CMF. Having HTML Parser and maybe those stripogram functions should be easy to integrate and provide Zope with a standard security mechanism for these issues. If people agree this a good idea I'll happily drive this forward.
