[Zope] advice needed

[gabecker@indiana.edu]

I am relatively new to Zope, but I plan to use it for an image database
system that I need to make for scientific purposes.  What I have in mind
is to store the actual images externally in files (since there will be
many and large files), and the info about the image (where collected,
owner, codes etc etc) in a database like MySQL. Zope would form the
interface.

My first question is what would be a suitable way to go from here: use
LocalFS or ExtImage for storage of many files (think of 50,000 or so)? I
will need to be able to differentiate between users: ie not every user
should have access to all files.

Furthermore: if there are people that have already done something similar
I would appreciate to learn from their experience. Through a web search I
haven't been able to find such projects, at least not based on Zope.

All best,
Gabriel
