Apple’s iTunes 4.9 looks for special tags in podcast feeds [pdf] to populate their directory and categorize the podcast.
Despite my mixed feelings on them adding new tags that seem to duplicate old tags, they’ve done it. Edd Dumbill has a great review of Apple’s RSS extensions. No need for me to repeat it here.
That being said, WordPress is my podcasting system of choice. With that in mind, Kevin Devin put together a replacement wp-rss2.php file for WordPress including the iTunes tags (this is the file that creates the RSS 2.0 feed). I wasn’t able to get his version to validate so I tweaked it and offer it to you.

If you’ve understood what I’ve said thus far, this file shouldn’t give you any trouble.
Update 30 June 2005: This replacement file now supports the “itunes:keywords” tag.
Update 4 July 2005: This replacement file now validates at the Nobody Likes Onions iTunes FeedCheck. Updates include better images handling, subtitles, and more standard RSS 2.0 tags.
