FWIW, Dublin Core started out *as* the short version. :)  If you
ignore most of the cruft,
http://www.dublincore.org/documents/dcmi-terms/ has the gist of it --
DC is just a relatively small set of elements for a metadata record
describing a resource.

More like a mapping from id3v2 to DC, like one found at
http://age.hobba.nl/audio/tag_frame_reference.html.  I'm not vouching
for that specific mapping, by the way, but it is an example.

Once you map from id3v2, you can express DC as XML, then have Zebra
index the DC natively.  Throw in some XSLT to display the DC in the
OPAC, and you can search and display this metadata without necessarily
having to map to MARC.  But if you want something to play with now,
you can map your DC to MARC per LC's crosswalk
(http://www.loc.gov/marc/marc2dc.html) and generate MARC records to
load into Koha.
