Have no idea what CDDB is. Always best to define acronyms and abbreviations
that might not be clear to all. At
least that way, we all may learn something.
CDDB = CD Database (OK, Compact Disk Database to be pedantic :-). See <http://www.gracenote.com/music/corporate/FAQs.html/faqset=what/page=1>. CDDB used to be a collective database effort to tag CD contents (on insertion of a CD, a checksum would be generated which, in turn, interrogated the collective database to get the contents out. It isn't 100% proof because the checksum method wasn't sufficiently granular to prevent repeats (more or less akin to the problem that plagues biometric identification of individuals). It's been superceded by a free version (www.freeddb.org) as the commercialisation appeared to have taken the work of many and made money for a few, creating the sort of money based unhappiness Douglas Adams reported on in his Hitchhiker's Guide to the Galaxy :-). I think it was mentioned as an example of a database where an identifier (the checksum) would pull out complete details, and as far as I know a similar idea exists for ISBN codes. But I'm not a librarian, just someone who's trying to find a decent solution for a home library :-). -P-
