So when Chris mentions JavaScript badges for del.icio.us, I think of Ed Eliot’s PhpDelicious or how to get similar results in WordPress. Naturally when he had the splendid idea to add captioning to YouTube videos with Google’s JavaScript API, I asked myself if there wasn’t a better way. There is, but to my surprise neither YouTube nor Yahoo! Video take advantage of that capability:

1. It’s common practice to implement text content in Flash via XML.
2. DFXP is a W3C XML standard for captioning videos.
3. There are free tools like MAGpie for creating captions, and they all support DFXP.
4. If YouTube or Yahoo! Video would allow users to upload and attach a DFXP file to a video, it would become dead easy for anybody to caption it. Not only for the filmmaker, captioning could be crowdsourced!

Just anticipating Joe Clark’s inevitable (and justifiable) objection: of course captioning is not an easy thing that anybody can do, to do it right it requires people with special training. But considering the number of videos on those platforms the only affordable and practical solution to provide any captioning at all is crowdsourcing. That can also be applied to the control of quality, accuracy, or reporting abuse.

Of course this would enhance primarily accessibility, but the XML files would further help search engines to index video content. And their marketing people would love such a feature for the positive PR!

Well, I submitted the suggestion both to Google and Yahoo!, you can vote on the Yahoo! Developer Network for it (Google is more closed-lipped). I’m curious who will be the first to offer that feature …
