I think we have to separate two notions.

- When I mark an element in HTML5, say, a section element, as being a 'chapter' or an 'introduction', that attaches some semantics to that specific part of the book. For me that is similar to what the Behavioral UI Task Force is looking at; today, this is achieved by @epub:type, in future I would argue that it should be handled by something like @ebook-type; it needs a set of terms which are very specific to the book structures. Is this what you mean when you say 'help HTML5 speak to bring our ebooks intelligence'?

- When I talk about the author, the editor, the price, the description, but even the access rights, etc, of a book, that is metadata that is on a different level than HTML5. The same metadata terms that are used for these can be attached, in theory, to a book fully in SVG, for example. That is the type of metadata that external tools, services, data centers, catalogues, etc, would use.

At least to my mind, the metadata task force is more about the second, what was also called 'structural semantics' is more about the first. And I think they are different in syntax, in goals, in terminology, etc.

Does this make sense, or am I completely wrong?

And in that perspective, we are just at dawn from what will be consuming content in the future, even from the titles we today distribute mainly on paper.

> For metadata to accomplish something, it needs to be both created and consumed. For us book publishers, ONIX is a good example of a very successful metadata standard. The people who make books create ONIX records that describe the books. We then send these records to the retailers, who use this information to populate their web pages. Consumers then read about the books, and (we hope) buy them. BISAC is another similar example—bookstores wanted to know which shelves to put the books on. Publishers, who presumably have read their own books and know what they are about, assigned codes to tell the bookstores what they needed to know. 
> Who are the consumers of all the other metadata we're talking about? Many of us publishers have already implemented some kinds of semantic data, like putting epub:type="chapter" in our ebook content. But is anyone doing anything with that information? We also want metadata to drive the discovery of our books. How would that work when most of our content is not exposed to the web (due to file formats, DRM, or the need for payment)? Who is listening, besides Google's spiders?
