Hi Tzviya,

This is information about the content, but it is also information that should be displayed to the user.  We encounter this at the publication level, the sub-publication (chapter or article) level, and at a more granular level in some cases.

I must admit I do not really understand the question. Do you ask whether this type of information can be put into HTML using microdata or RDF (well, encoded in RDFa)? The answer is yes, provided that there is an agreement in the vocabulary. But, say,

<span property="some_vocabulary_term_for_chapter_number">Chapter X</span>

in RDFa is possible, and it would provide a statement roughly of the form

<> URI_for_some_vocabulary_term_for_chapter_number "Chapter X"

when turned into RDF, where <> here stands for the URI or some sort of a reference (DOI?) for the book as a whole. Similar can be done in microdata. Of course, property (or itemprop in microdata) can be used by CSS for styling, too.

But I am not sure this is what you ask...

Similarly as above, both microdata or RDFa can be used for this.

I see two issues:

- what is the reference to the book? Does each ebook has such thing? A DOI or anything similar?
- encoding in RDFa/microdata is possible. But who does what with this information? Extracting, say, RDF from that information is possible but then so what? What is the usage?
