The Future of the Web
The debate over supporting RDFa within HTML5 has been burning hot. A quote from the editor of the HTML5 specification reveals what the friction is really about:
It’s not clear to me that the future of the Web is structured data. If anything, I’d predict it was unstructured data. It would be useful to know why you think structured data is the future. - Ian Hickson
I’ve heard similar sentiments from others at Google. And it’s true, Google is great at understanding unstructured data. But for the rest of us application and script writers, structured data is especially useful. Until the layman’s tools for information gathering are on Google’s level, any realization of a Semantic Web will depend on structured data.
