[Zope] Advice on small zope application

[Stefan Loidl]

Hi,

I need some advice on the easiest way to realize a small zope application.

The application should allow users to upload (mainly
Visio-drawings) to the Zope server and manage them.
Other users should only be able to download the files.

Requirements:
- upload, update (i.e upload a replacement for a file) and deletion
   of files should be possible
- files should be saved in the filessystem, not in the Zope DB
- it should be possible to structure the files in a tree
- the owner should be able to add comments to the file

Nice to have:
- only the owner should be able to update/delete a file

Are there any Zope products that fulfill this requirements?

Any ideas?

Thanks!

Stefan
