[Tof-general] Directory Permissions

[Miguel Koren O´ Brien de Lacy]

I just want to confirm the minimum directory permissions I need. I set 
up $basePath and created a directory for a user under it. This directory 
I left with the default permissions set up by the server. Then I created 
a directories for 2 rolls (photos-digital and photos-scanned). The 
permissions I used for those directories are:

700 nobody nobody (the apache user is "nobody")

and the photos themselves are set to:

600 nobody nobody

Is this correct?

The other questions is about "rolls". If I want to classify the pictures 
as "travel" and "business" for example,  would they need to be in the 
same "roll"? I have some scanned and some digital pictures which would 
fit in the same category and I wonder if I should have just ONE roll for 
my user? The deeper question is "what is the purpose of the roll"?
