[Zope] advice needed

[sean.upton@uniontrib.com]

On the other hand, since you have a system writing files to disk, it might
be better to have a security mechanism pre-built into your framework -
instead of having to roll your own from scratch like you would with PHP.
Zope wins in the security department too.

Here's my advice: use the CMF.  Create a content type that stores the binary
externally.  Decorate it with simple metadata (DCMES, and potentially other)
stored in the object database, and write ZSQL methods, templates, and python
scripts as skin methods that for that content type.  Use the identifier/path
of the object as a string-based key in your RDBMS for tabular data that
decorates your main object.  Make the UIs and methods that view and
manipulate the said data CMF actions to add onto your object.

IMHO, this is a powerful hybrid-storage design idea, and I hope this is
helpful?

I'll probably get shot for this, but a pure filesystem and MySQL
implementation is better suited for PHP. If say, you wanted to store the
image info in the ZODB, and the data elsewhere, then Zope is a good
solution. Another nice thing about Zope you don't get with a language like
PHP is much better managability of the presentation code. If that's
important, then again, Zope is the way to go.
