Semantic Web training videos
Marco Neumann of the New York Semantic Web Meetup suggests VideoLectures.net as a good source for Semantic Web training videos. In fact, here is a link to the results of searching that site for "Semantic Web": VideoLectures.net for "Semantic Web". The videos range from events, to invited talks, keynote presentations, lectures, panels, and tutorials.
I have not watched any of these videos in any detail to recommend them, but the one entitled Introduction and Overview to the Semantic Web by James A. Hendler sounds like a good starting point, or at least as a place to get the viewpoint of one of the original "biggies" of the Semantic Web.
I can't wait to watch some of these videos.
