In order to not get completely ignored in the technology and sciences
sectors, a bibliography microdata format needs to be able to plug into
the network effects of BibTeX. Having a non-flat microdata format
while BibTeX remains flat would seriously hinder conversions from
microdata to BibTeX.
How are non-flat bibliographies (beyond an article being in a book /
journal / Web site) presented?

More to the point, allow to be extracted and used as bibliography
source data for another publication to avoid repetitive data entry.

OK. The styles that I've observed make a difference that isn't
traceable to the availability of fields on an item have mainly made a
distinction between atomic publications and compilations.

On the surface, it seems that it would possible to mint more field
types and publications for BibTeX to support those cases, but what is
the publication type information used for? Are there as many different
entry presentations as there are entry types? Or are the type tokens
supposed to be mapped to localized human-readable label strings?
Also, the non-flatness I see is an item being part of a compilation
which is already supported by BibTeX without allowing the whole model
to generalize into a graph.

It seems relatively straight-forward technically to extend BibTeX with
the field types from OOXML that BibTeX doesn't cover. The main issue
seems to be the bikeshed of what names to use.

I don't see a fundamental reason why the BibTeX vocabulary couldn't be
extended with stuff from there.

What formats/software do people use for cases like that in practice?

But vCard required both N and FN, so if you only have FN, you can't
get an N without a lot of dictionary-based domain knowledge and
special rules. (Or you can make a GIGO N...)

Maybe there are different needs for humanities and law. I don't know,
though I'm skeptical. Is there one dominant format for humanities and
one dominant format for law? (I notice that ACM and Google have
EndNote in common in addition to BibTeX.)
It doesn't make sense to adopt something less established in order to
avoid favoring sciences. That is, it may turn out that some fields
need a format that is less flat that BibTeX, but offering that kind of
generality where the flatness of BibTeX works seems to be the kind of
complication that only makes people stick to the simpler thing they
already have, i.e. BibTeX.

Is conversion from DC to BibTeX well-defined? Wouldn't it open all the
same issues that extending BibTeX vocabulary involves? What
bibliography generators support DC as source data?
