The Open Podcast Prefix Project hopes to take podcast analytics into the public information realm.
By adding a specific coding block into the URL of an episode, podcasters can open up their download data to the rest of the podcast and A/V development community, creating a networked dataset to help measure the industry.
Specifics on setup, privacy, and the API for public data, as well as a sample stats site, are all available on the OP3 website.
