On wikipedia I read the articles about:
- cddb
- freedb
- Gracenote
- MusicBrainz
Description of the cddb file format.
Java example to calculate the id.
MusicBrainz Homepage
Calculation of the MusicBrainz DiscID.
Don't use the old RDF based libs for new projects. There is a new RSET WebService and the used XML meta format.
On cpan exists a perl module, but it is in a very early development state.
With the libdisci (see the example usage) I'm able to convert the cd-discid into the MusicBrainz DiscID.
