HI Uma,
Just to answer your question directly about ID3v1, your proposal and
project should have an answer that is not specific to the particular
metadata format (e.g. when possible it should work with any metadata format
that taglib works with and every format that Mixxx supports -- MP3, Ogg
Vorbis, FLAC, M4A, WAV/AIFF/RIFF, etc. In some cases it just wont be
possible such as with WAV/AIFF/RIFF. You should research each one to make
sure you know what is possible).
I agree with Daniel that DJ-specific metadata can't easily be stored to
existing metadata container formats because there is no existing standard.
We have considered defining a standard in the past but we don't believe we
could get all the stakeholders (VDJ, Traktor, Serato, etc.) on board.
Hope that helps,
RJ
