JSON Feed includes an attachments array, which is similar to the enclosure element in RSS that enabled podcasting. We love podcasting and included an example podcast feed in the JSON Feed specification. However, because the Apple podcast directory and its RSS namespace are so central to many podcasting tools, it wasn’t clear how quickly podcast apps would adopt JSON Feed.
I’ve also pushed up a change to the WordPress plugin on GitHub to add support for attachments. After some more testing, I’ll update it in the WordPress directory.
Update: FeedPress also just announced support for JSON Feed. This is another important one for bloggers and podcasters. It effectively gives a JSON version to everyone using FeedPress, even if the FeedPress customer’s site is still backed by an XML feed.
