So how do you get media without a title? Upload media, edit it, clear the title, and save changes. Maybe saving media with no title should not be allowed.

Our atom feeds use taguris (RFC 4151).

First thing to re-evaluate: Do we want to/have to use taguris in this place? There might be good reasons to want this.

taguris have the form {ownerid_namespace}:{localpart}. This is so they are human generatable AND universal unique. the {ownerid_namespace} is formed of {DNSname_or_email},{date}. The date is the time when the domain/email was owned by the author. This is so that a domain can go to a new owner, which in turn has a new namespace.

For feeds owned by a user, we can use the registration date of the user. We currently use the *current* year. Which is plain wrong. Because the id should never change after first being shipped. So this should be fixed soon.

For site feeds we currently use 2011 as the date. We probably should switch this over to something like the "deploy date". The problem is how to find out about it. We could use the date of the oldest entry in the db, but that will change when the oldest image gets deleted by the owner. ("You may not delete the master goblin image.", hoho). No easy solution currently available.

These configurations for apache either cause a 500 error, or they send the browser into a 301 loop with the requested page.

for instance, this is the error produced by the wsgi method:

I've also tried using the following config, but get a 301 redirect loop to the requested URL itself:

ProxyPass "/test" "fcgi://localhost:26543/"

A coworker managed to get the server past 500 errors with some configuration of the fcgi method, but we ended up with a redirect loop anyhow.
