DESCRIPTION

This module generates metadata about CPAN modules (and BACKPAN) modules in RDF format.

It requires a local CPAN mirror (for example, mirrored using "/usr/bin/rsync -av --delete ftp ftp.nic.funet.fi::CPAN /path/to/local/cpan/") as well as a local BACKPAN mirror (for example, mirrored using "/usr/bin/rsync -av --delete pause.perl.org::backpan /path/to/local/backpan/").

It currently uses an SQLite database as a temporary datastore. It takes about two hours to generate the RDF file from scratch. I don't expect many people to run this module. I run it occasionally, and you should be able to fetch the latest version from: http://www.cpan.org/authors/id/L/LB/LBROCARD/cpan.rdf.gz
