The feed is generated from the collection, so you have control on how many items you want to list. You're not limited to using a blog structure, this is just an example. The property

feed:
    podcast: true

is crucial to avoid generating the normal RSS feed.

Call yoursite.com/blog.rss to get the feed.

Each page under this collection will have episode information in the page header. If a blog post does not have the podcast attribute, it's not included (so you can have other posts as well)

podcast:
    title: Episode 1
    description: "Description"
    summary: "Summary!"
    subtitle: "something"
    enclosure: https://mysite.com/myfile.mp3    #audio file link
    guid: 1                                     #unique identifier for episode
    duration: "0:43:23"                         #format: "H:MM:SS"
    pubDate:                                    #optional, if not set uses post date. Or use "Thu, 02 Feb 2012 00:00:00 EST"

Hello World

[jgonyea]

If this helps anyone: http://itunespartner.apple.com/en/podcasts/faq

I am planning on making a plugin very soon to assist with setting this all up via the admin gui.

Thank you much for the jump start, @flaviocopes

[flaviocopes]

Yes, maybe it's better spinning off this PR to a separate plugin, there's lots of things you can add to make it better and simpler for podcasters, including mp3 file uploads in the blueprint etc.

I'll leave this open, but if you start work on a separate plugin, I'll then close this.

[jgonyea]

Yes, I'll start on a podcast plugin.

[jgonyea]

Podcast plugin is submitted to grav issue queue. Let me know if you need anything else.

[jgonyea]

I think this PR can be closed. Podcast plugin is available via gpm.
