We will probably have to increase the coverage in due course, yes.
However, we should verify that the mechanism works in principle before
investing the time to extend the vocabulary.

If such data is important, we can always add support when this becomes

| organizational and process problem: that the WHATWG and/or the
| W3C-neither of which have expertise in this domain-become the
| gate-keepers for such extensions. In either case, we have a rather
| brittle and anachronistic approach to extension.
I don't see any of this as a problem.

I don't understand this point. Could you provide an example of this
| 5. Aspects of BibTeX's core model are ambiguous/confusing. For example,
| what number does "number" refer to? Is it a document number, or an
| issue number?
What's the difference? Why does it matter?

| 1. reuse Dublin Core and vCard for the generic data: titles,
| creators/contributors, publisher, dates, part/version relations, etc.,
| and only add those properties (volume, issue, pages, editors, etc.)
| that they omit
This seems unduly heavy duty (especially the use of vCard for author
names) when all that is needed is brief bibliographic entries.

This is already possible.

The mapping to RDF is already defined; further mappings can be done using
the "sameAs" mechanism.

"url" seems widely supported and I included it. I haven't added any other
fields yet; I imagine that once this feature gets traction, we'll have
more direct data as to which fields would be most useful, and then we can
see what common practices are in the bibtex world for those cases and use

Right. That's a good thing. It makes the vocabulary more usable.

No, not at all. The point here is exclusively to address the use cases

So far based on my experience with the Workers, Storage, Web Sockets, and
Server-sent Events sections, I'm not convinced that the advantage of
getting more review is real. Those sections in particular got more review
while in the HTML5 spec proper than they have since.
