About the properties

id

The book id is unique to a particular "idea container". E.g. you might have multiple languages and/or editions of a book with the same id.

The id must be uri-safe. That is, no character other than letters and numbers.

For best results, use an id created from an md5 hash as follows:

use Digest::MD5 ();

my $domain = 'example.com';
my $title  = 'The Title of Your Book';
my $author = 'A.U. Thor';
my $id = 'x' . Digest::MD5::md5_hex(join('_', $domain, $title, $author));
serial

The serial number corresponds to a particular "printing" of your book. This might be a particular translation of a particular edition or whatever.

Two copies of a book with matching id+serial numbers are assumed to have identical content. Annotations and links apply to a given book id, but a different serial number tells us that they might not directly line-up in another edition/translation/etc.

If you're looking to identify a particular copy of a book (e.g. personalized to the user or whatever), this is probably not the attribute you're looking for.
