Example author:

  http://purl.org/NET/cpan-uri/person/gwilliams

Example distribution:

  http://purl.org/NET/cpan-uri/dist/RDF-Trine/project

Example version:

  http://purl.org/NET/cpan-uri/dist/RDF-Trine/v_0-118

If you visit the page of a version that cannot be found on CPAN, then the
wrapper naively assumes that it does/will/did exist, so serves up a page
anyway:

  http://purl.org/NET/cpan-uri/dist/RDF-Trine/v_9-999

Note that the final segment of version URIs always begins 'v_' and
is followed by the version number with dots replaced by dashes. This
token is a valid qname local part in Turtle.

If module authors use Module::Install::DOAPChangeSets and include a
Changes.ttl file in their distribution, then the project data will
automatically pick up data from Changes.ttl:

  http://purl.org/NET/cpan-uri/dist/RDF-TrineShortcuts/project

The Changes.ttl files for RDF-TrineShortcuts v0.06 and for
Module-Install-DOAPChangeSets v0.04 itself are considered good examples of
how to write Changes.ttl files.

Distribution maintainers are free to use any other URIs beginning
with <http://purl.org/NET/cpan-uri/dist/{Their-Distribution-Name}/>
to identify whatever they like, though this service cannot be
guaranteed to serve up any data for them.
