I'm looking into developing an API for publishing videso/audio/etc to
iTunes using Rails. Has anyone done anything like this? or can point
me in the right direction? The web doesn't seem to have anything on
it, regarding Rails or other technologies.
iTunes uses RSS. Just publish RSS with the itunes tags, and anyone
can add that feed to itunes and subscribe. Yahoo has some media
extensions to RSS's enclosure element as well.
you might also look at OPML parsing since many of the podcatchers use it…and if you want people to be able to export their subscriptions into your app itd be good to have a parser.
here’s one i’ve used in the past (i didn’t write it, but it works)
parse_opml (opml_node, parent_names=)
