I don't know if I agree that it can't prevent it, but should it is an
interesting question. How much do you value your disk space? Sure, space is
getting cheaper all the time, but the amount of information to be stored is
growing even faster. Digital photography, for example is just now taking
off, and file sizes get larger and larger with each new generation. I think
I will have to create a redundancy checker that runs as a chron job and
replaces redundant files with sym links. Maybe this is how it should be.
Pmwiki will not be responsible for controlling redundancy, but some other
external program. I've just about given up on trying to change user
behavior. I think they're just gonna do what they're gonna do, and systems
are going to have to be smart enough to deal with it. (This is what happens
when you work in network management for a while)

I agree that redundancy is bad, but it's not something that PmWiki can
(or should) prevent. What is better is to come up with mechanisms that
encourage the right behaviors at the user interface level.

I'm open for suggestions about how this ought to work. I'm wanting to
avoid overloading the query string too much, however, or creating lots of
special-purpose "Handle*" functions. I'd rather have a markup that means
"generate list of XXX" here.

Agreed, which seems to argue towards the attach-to-page model for file
uploads. I guess I haven't heard anyone arguing for the "throw everything
in a common pool" model yet, so we might as well assume the page
attachments model is the way we'll head. If anyone feels differently,
now's a good time to speak up before we get too committed to the other
