Dear David,

I do not know if somebody already replied...

my answers to your questions are below.

Personally I would map TPE1, TPE2, TPE3, TPE4 to xmpDM:artist

This is a tricky thing - we are again on the FRBR level, because 
actually we have different creators (the composer/lyricist, the 
performer is also a kind of creator, the guy who made the recording, but 
also the guy who created the mp3 is a kind of creator)

I am not sure about this, to be honest, when we only have one level.

I would map TOPE (which is the original performer), the composer (TCOM) 
and the lyricist (TEXT) to to dc:creator

If this property means the person, then this is again another creator 
(see my answer above); either we map it to dc:creator or we have to 
introduce more abstraction levels for which we then should introduce a 
new line for the encoder.
If it means the encoding tool then we could map it to xmp:CreatorTool

I would map TDRL to dc:date and TDAT to xmp:CreateDate.

All of the question you posed are tricky. I am therefore looking forward 
to discuss this further.
