[Vorbis] Indices and totals

[Ross Levis]

This was discussed a couple of years ago and a few of us decided to use
TRACKTOTAL for storing the total number of tracks in an album.  It's not
an official tag but I implemented this in WinVorbis.

Hi all!

I've read http://reactor-core.org/ogg-tagging.html and
http://www.vorbis.com/ot/20030303.html#id2726753 about the goals and
non-goals of vorbis comments, but I'm still unsure:

1) Is it by purpose to forget about CDA's index feature because it's so
rarely used or did nobody here ever thought about it?
-> Add an INDEXNUMER field?

2) If "Vorbis comments are the equivalent of a quick note scribbled on
the bottom of a CDR", it would be nice to know the total number of items
in a series to be shure to have all parts together (at least I note the
total number of disks on the bottom of a CDR). So what about the
conceptually same:
-> Add a TRACKTOTAL, DISKTOTAL and INDEXMAX (not INDEXTOTAL for
disambiguation, since indeces count from zero in the red book standard)

3) Or would you consider it wiser reusing (abusing) existing standard
vorbis fields and note the total number of disks/tracks/indeces inside
the very same field like TRACKNUMBER=3/15 or would this break more
things since apps expect a number in there? Or even stuff the indices in
there too, like TRACKNUMBER=3/15.2/5? Or maybe also the disk number
TRACKNUMBER=1/3-3/15.2/5?!

I personally dislike 3) and have currently coded it with seperate new
fields. But since I'm free to change the application in any way I want,
some guidance on this topic would be really appreciated!

Thanks in advance,

Mark.
