The BITSPS can't be changed because it is already being used. However, the
BEATS_PER_MINUTE could be changed to either BPM or BEATSPM if you think one or
the other makes more sense.

Despite what I wrote in the email, I actually put this in the specs:
These should cover both the TRCK and TPOS tags in ID3.

No, but I am guessing that her name is in the booklet under that song. I'm sure
that if you did a poll, you would find that there are a lot of people that would
store this information under different places. We really need examples to say
what is appropriate.

This field is already used so it can't be changed. However, we need to clarify
how to use it.

They have the same meaning in my mind so I don't see a reason to change it.

Perhaps, given the description, it should be INTENDED_PRODUCT? This tag comes
from the RIFF specs and I couldn't find a very good description of it.

This change might induce somebody to store more than one instrument in a tag,
which is a no-no. From the specs, "Multiple items should never be stored as a
list in a single TagString."

Is that really better with DATE_RELEASE just above it? To my eyes it looks
better this way, but I am not sure. I asked in IRC and one person responded
that they prefer DRO. "don't you like french word order?"

Makes sense, changed.

I originally started with DATE_START but changed it. It makes little sense for
most items where you only tag a single date, and not a start and end date.

Should a difference be made between lead performer and other performers?

I assumed it was the same as the ID3v2 TPE1 tag, the Vorbis PERFORMER tag, the
CD CDROM_CD_TEXT_PACK_PERFORMER tag, and the RIFF ISTR tag? Should there be a
difference between a lead performer and any other artist?

In some cases the "ORIGINAL" title is used for remakes (ORIGINAL_ARTIST). In
others it is used to denote the source (ORIGINAL_FILE). I would hate for these
two to get confused. Is there something that you could recommend?

I think that CREDITS sounds better and would probably be more intuitive, but it
would probably induce people to store a list in a single tag instead of multiple
> - EDITION -> VERSION
For DVDs, this is always referred to as the Edition. For instance, I have DVDs
that are "Directors Cut", "Collector's", "Ultimate", and various other editions.
Is this done differently with CDs?
One other thing, where should we store if a source was widescreen or fullscreen?
And I mean in a generic sense. The dimensional proportions could always go in
ORIGINAL_DIMENSIONS. Should there be a different place where someone could just
write "Widescreen" or "Fullscreen"? Maybe "Anamorphic Widescreen" (1.66:1 to
2.35:1) and "Full Frame" (1.33:1)?
How would you store this DVD of mine?
Bruce Campbell vs. Army Of Darkness
The Director' Cut
Official Bootleg Edition
Photos available here:
And yes, the DVD actually says "DVD-R4x Not Really Recordable 96 MIN" and
"Un-Recordable 1x-4x Compatible"
