ATOM Example

[Alberto Ruiz <arc gulic org>]

I promised thos to send an example of atom for the feeds on 
art.gnome.org, so here it is.

We have to discuss some things, we decided to move from RSS to ATOM 
because the icon and logo items to use them for the thumnails, but, 
looking closely at the specification, I've noticed that the logo and 
icon items are only for feeds and not for entries, so there is no real 
advantages, but the clear and better specification docs of ATOM over RSS.

* RSS spec don't says anything about how many enclosures tags are 
allowed inside of an item, so we have no good ways to fit the standard.
* ATOM lets you (explicitly) so many <link rel="enclosure" .../> inside 
an entry as you want.

Some things that I'm not sure how to handle.
¿Should we use one <entry> for each resolution/format of the same 
background?
¿Should we use one feed for each class of themes? (Backgrounds, Gtk 
themes, etc...)

Since we have a last updated section, one feed section per class of 
themes doesn't have sense.

My opinion here is that we have to extend the spec with an agnostic 
namespace for specific attributes:
<link rel="enclosure" theme:type="background" 
theme:resolution="1280x1024" .../>
<link rel="enclosure" theme:type="thumbnail" .../>
<link rel="enclosure" theme:type="gtk" theme:engine="clearlooks" .../>
<link rel="enclosure" theme:type="metacity" .../>

What do you think guys?

PD: I'm not a RSS/ATOM/${feed} expert, so comments and ideas are really 
wellcome.
