RDF Radio "So what's RDF Radio? Mostly vapour right now, but it's a concept Matt Croydon and I have been tossing around for a few weeks. The basic ideas of which are a little similar to Nokia's much touted but equally vapourous Visual Radio.
The main tenet of both is to provide some additional metadata about an existing "Radio" audio stream on a side channel. Visual Radio appears to be quite tightly constrained around proving visual (wap/html based?) user oriented information over GPRS as an adjunct to FM radio. RDF Radio on the other hand is intended to provide timely pure RDF/XML metadata that supplements any broadcast stream; FM, AM, webcast and much more."
