[vorbis] (Classical) Request for Standardization of expanded TAGS

[Jonathan Walther]

A month or two ago I sent an email to this list proposing to expand
the list of "standard" tags for Ogg Vorbis.  No tag would be required,
but if you wanted to encode certain types of information about a file,
you could use a standard tag.

I went through the whole discussion, and revised my proposal in light
of all the comments from everyone.  Here is the updated proposal.

This document is written in the context of
     http://www.xiph.org/ogg/vorbis/doc/v-comment.html
which hasn't been updated since Feb 19, 2001.If a tag can denote
a list of items, and not just a singleton, repeat the tag for each
item, one item for each usage of the tag.  After the list of tags
and what they mean, I will give an example that attempts to use
each one, then a more "normal" example, then a minimal example, and
what the result would look like when played by ogg123.

At first, I just meant for these tags to help out the Classical music
side of things.  But I've been assured that (other than Opus
and Conductor) these tags are equally as useful in Pop music.
Although with Metallicas "Enter Sandman" you might even need the
CONDUCTOR tag, for the guy who conducted the cello players.

--------------------------------------------------------
First, a few tags are now DEPRECATED:

VERSION
        version information is typically included in the title,
        such as "Doctoring the Tardis - 12" Remix"

DESCRIPTION
        role subsumed by ADDENDUM tag

ORGANIZATION
        role fulfilled by PUBLISHER, PRODUCER, LABEL,
        and COPYRIGHT tags.

ARTIST
        role fulfilled by COMPOSER, LYRICIST, PERFORMER, ENSEMBLE,
        CONDUCTOR, AUTHOR, PRODUCER, and ARRANGER tags.

--------------------------------------------------------
We are then left with the following RECOMMENDED tags:

OPUS
        the number of the work; ie, Opus 10, BVW 81, K6
        for a regular opus, just type the number, eg "10".
        For corner cases, type in the full designation,
        such as "BVW 231".

COMPOSER
        composer of the work. ie, Gustav Mahler

ARRANGER
        the person who arranged the piece.

PRODUCER
        the person who produced the recording

PUBLISHER
        webmaster from Hyperion will explain this
        one; its necessary for radio stations. if it
        turns out to be the same as the COPYRIGHT tag,
        I'll recommend we drop it entirely.

LYRICIST
        the person who wrote the lyrics
        
AUTHOR
        author of spoken text, eg, JRR Tolkien

CONDUCTOR
        conductor of the work; ie Herbert von Karajan

PERFORMER
        individual performers singled out for mention;
        ie, Yoyo Ma (violinist)

ENSEMBLE
        the group playing the peice, whether orchestra, choir,
        quartet, or rock group. ie, Berlin Philharmonic

LABEL
        the record label or imprint of the CD.

ISBN
        if found, put ISBN or EIN of the compact disc here.

ISRC
        documentation isn't available, but if you need it...

DISCID
        since the EIN, ISBN, etc numbers aren't to be reliably found
        on the CD, nor is the catalog number reliable, the FREEDB
        index hash should go here

TRACKNUMBER
        the track number on the CD

ALBUM
        if appropriate, an album name

TITLE
        "the work", whether a symphony, or a pop song

PART
        a division within a work; movement of a symphony, eg.

TYPE
        type of work, ie, symphony, concerto, song, speech

GENRE
        id3 type classification (classical, pop, jazz, blues, etc)

DATE
        date of recording, if known

LOCATION
        location of recording, if known

COPYRIGHT
        who holds copyright to the track

ADDENDUM
        additional comments pertaining to the piece.
