You fail to explain why you think DC's class (sic) names are a problem.

On the contrary: DC is based on a deep understanding of the metadata
published by the type of organisations for which (and by whom) it was

DC is not only for citations.

Before you can assert that, you should, at the least, state which
question you think applies.
My above comments not withstanding, more effort towards completing the
'citation' work (and that for several other of the much-needed, pending,
microformats) would be a good thing. If this community does not do it,
some other group probably will.

If so, a facility for using it on "visible" metadata would be an
improvement, would it not?

There *is* support and there *are* tools, not least in the fields for
which it was intended. It is even government-mandated in some quarters.

That's not necessarily a bad thing (after all, HTML was first designed
for academic projects!).

There is a requirement on the wiki that opinions are marked up as such -
see point 4 on:
Folks new to DC might like to read:
and note in particular the distinctions between "simple" and "qualified"
DC, and that the former has just 12 properties:
(By way of illustration, Qualified DC takes a property, such as "date",
from Simple DC and makes properties like "date.created" and
A method of applying DC using HTML class names on published data would
be 'A Good Thing', and could be used alongside existing microformats.
<span class="audio-title">DigitalPlanet Podcast</span>
<abbr class="published" title="20071029">29 Oct 07</abbr>
could, using a wrapper class to encompass the item to which the DC
metadata applies, become:
<div class="haudio dc-wrapper">
<span class="audio-title dc-title">
DigitalPlanet <span class="dc-type">Podcast</span>
<abbr class="published dc-date-created" title="2007-10-29">
29 Oct 07
which could then be parsed by DC consumers, without the need for such
consumers to be updated each time a new microformat emerges.
Note, for example, the use of:
in an hAudio; whereas an hReview would have:
and an hListing might use:
Whether such usage is called a microformat, "POSH" or some other term is
really a matter of bike-shed colouration.
