Custom feed attributes in FOAF or OPML

Hi all,

I have a list of subscriptions that I want to use on
multiple Planet
installs. The recommended way of doing this is with a FOAF
or OPML
file, but as far as I can tell there's no way to add custom
attributes
to those formats. My feed entries look like this:

[http://
feeds.simonwillison.net/swn-everything]
name = Simon Willison
face = simonwillison.jpg

Since OPML encourages inventing abritrary attributes, how
about having
it so that any unrecognised attributes on <outline />
elements in an
OPML reading list are treated the same way as unknown
attributes in a
regular config file?

Cheers,

Simon

Might sound a touch medieval, but I've used a quick Makefile
to cat Planet
configs together in the past. 

(Would be sweet if ConfigParser had very simple Include
functionality...)

That's almost exactly what I'm doing  Here's the
site:

http://oxfordgeeks.net/

I'm sharing the subscription list between the "5 most
recently updated
blogs" on the homepage and a full Planet at
http://planet.oxfordge
eks.net/

I'll have a go at hacking the OPML feature some time soon.

Cheers,

Simon

Ah, there's a better way of doing this: Create a new output
template for
your Planet, and include it in the front page. No need to
share lists or
bother with two Planet runs. Snippets of config as an
example:

[Planet]
template_files = index.html five.inc.tmpl [...]

[five.inc.tmpl]
items_per_page = 5

five.inc.tmpl should be a very minimal template, which you
can include on
your main page. I imagine you already have this bit, though.
 I
use this
often to share simple sidebar lists of recent posts among
related Planets.

Thanks,

- Jeff

Brilliant, thanks. I hunted around in the documentation for
a way of
spitting out two different templates from one config but
managed to
miss this.
