In short, Dublin Core isn't being used by Google.

From memory Dublin Core was being used by Google Scholar, it was never used by Google (general) Search. And they don't use it. However I am sure it is being used for something somewhere (but not for the big search engines as far as I know), but I forget. Sorry for being human ;-)

The cuetimes listed on this page are functional while the live broadcast continues and also once Youtube has finished processing the public broadcast. Processing time varies between 6-24 hours. During this period the clip is viewable in full but the cuetimes cannot be relied on.
