Yes, I'm conflating cataloging metadata and citation metadata a bit.
Cataloging cards typically have access points such as the main entry,
subject headings which guided how the card was filed in the physical
catalog. Citations do not have these typically.
With the advent of online catalogs this distinction is blurred quite a
bit given the availability of freetext searching, and being able to
search against any metadata field, not just the main entry, subject
I'd argue that as a microformat the distinction gets blurred even
further since the artificat being processed by the machine is the
actual display of the citation metadata.

Agreed. Expecting microformatters to learn AACR2 and MARC's byzantine
tagging mechanism is a non starter. By definition MARC (Machine
Readable Cataloging) was designed for machines to read--not humans.
This is evident in the numeric tags that have no semantic content,
apart from what trained catalogers know them to be. MODS on the other
hand takes the semantics of MARC and associates the numeric tags with
pleasant human readable tags. There might actually be some potential
for MODS as a microformat.
That being said I'd love to see some MODS as microformat examples in
the wiki...and am enjoying this thread.
