Its probably worth noting that this was our MP3 embedding scheme for a
while, back when we only used the TCOP ID3 tag for the copyright
statement.  Assuming you make it a "specification" (i.e., this is the
text you use, these parts are optional), we were able to split out the
bits we were interested in with tools like ccLookup just fine.

It's worth noting that the EXIF 2.2 spec gives specific format
information for the copyright field, and it looks somewhat similar to
what Mike quoted above.  Perhaps using what they suggest, with the
license/metadata URI appended?  See page 29 of the spec
(http://exif.org/specifications.html).
