liveTopics in RSS2.0.
Is this the first valid RSS feed with topic metadata?
Today I've finished the experimental RSS generator for Radio that exports the associated liveTopics with each post in the RSS feed. At the moment topics are contained in a "liveTopics" XML namespace.
This will enable a smart aggregator to use the topic's for filtering & combining feeds together.
[Curiouser and curiouser!]
This is where it gets interesting, very interesting. It's going to be the beginning of a new generation of knowledge management tools.
