What do you do for the tracks on the second or subsequent disc of a
multi-disc set?
Good question! For vinyl (double-sided), I've been using A1, A2, B1,
B2, etc., but that doesn't seem scalable. I just did a bit of
research and found this:
http://atomicparsley.sourceforge.net/mpeg-4files.html
Based on the data here, I'd propose changing "position" to
"track_number", and using "disk_number" for multi-disc sets. Do you
think that would work?
We should also be careful to distinguish /types/ of identifier
(catalogue number, UID, ISBN, Amazon-ASIN, etc.)
Since those other than catalogue number are proprietary
identification methods, i.e., identifers for external systems, the
role of
"identifier" should go to the primary source, the record
label or publisher.
ISBN is not "proprietary", neither are "International Standard
Music Number:
<http://en.wikipedia.org/wiki/International_Standard_Music_Number>
and the other, related identifiers listed at the foot of that page.
Perhaps we need type/ value pairs for them?
"Proprietary," as in "something owned, trademarked, registered, or
protected." ISO developed ISBN and ISMN, so I believe those formats
would be considered proprietary to ISO. But I don't mean to bicker
for the sake of argument -- I'm trying to differentiate between the
arbitrary primary identifier, closest to the source of creation and
publication, the catalog number, and an additional source of
identification into an external system, ISBN/ISMN. I hope that makes
sense! Might not be tremendously important, though.
Type/value would certainly be a good solution (I see you've mentioned
that before in the archives...just catching up now...I disagree that
the URL of a downloadable file would be a sufficient unique identifier)
So, having browsed http://microformats.org/wiki/uid-brainstorming,
I'd like to know if you think that the previously-proposed abbr
format would work?
<abbr class="uid" title="urn:ismn:555555">5 555 55</abbr>
<abbr class="uid" title="catalog">DTR008</abbr>
I realize I'm rehashing a conversation that already came and went in
June, but I'm new to the list.
Thanks,
Justin
