Hey Jukka, So you're seeing the delineation more as:
* metadata = document level stuff * XHTML = textual representation [which can included finer-grained what I would call "metadata" too] ? If so, interesting, I wonder then if there should be some sort of rethinking then of the way that we capture or represent the XHTML because I would think that our existing Metadata object could be reused at that level too. Maybe have like a textual/XHTML metadata object as well, where the keys were things like the IDs (or some generated ID) representing each XHTML tag (where nesting is something like key=outer tag/inner tag 1/inner tag 2) and where the values were the attribute values themselves. I wonder if this would work as a representation format. Then it's easy to define "views" on top of the Metadata object like an hCard view, or an "XHTML" view [with attributes and w/o]. WDYT?

The Metadata object can only represent document-level metadata, so it's not suitable for things like: * this paragraph is written in French * the bounding box of this word is X on PDF page Y * this phrase is a hyperlink to URL X * these words denote a physical address XHTML attributes are a perfect way to represent such annotations. It would be great if we could leverage some of the applicable microformat standards like hCard to simplify downstream use of such information.
