Linked data on youtube?

I thought I’d try writing some RDF/Turtle as I see it on youtube.

<http://youtu.be/jP6kzKygaOs>
dc:title "Jason Silva on London Real talks about Vanilla Sky";
dc:publisher "London Real";
dc:subject [
  dc:subject "Vanilla Sky"
  dc:type "Film" imdb:homepage <http://www.imdb.com/title/tt0259711/>
  tmdb:homepage <http://www.themoviedb.org/movie/1903-vanilla-sky>
  ]
cities:city "London".

Kind of reminds me of when people started hacking Triples into Flickr by using Machine tags. Still its interesting to see Youtube adding the ability to add a triple in a nice clean way (if its a well used ontology of course)
