Broadcast microformat under development
This is just a heads-up to point out that a microformat for Internet radio and TV has recently started at: microformats.org
Microformats are a way of adding markup to human-readable data on web pages so that information can be extracted easily by software - a broadcast microformat would allow media players, Internet radios and search engines to extract detailed information about radio and TV stations from web pages.
The microformats development process starts with the capture of examples to discover how people are currently providing information on the web. If you publish webpages which feature Internet radio and TV stations it would be really help if you could list these at: microformats.org/wiki/broadcast-examples
