 Resource Description Framework (RDF) is a standard model for data
 interchange on the Web.
 .
 Test::RDF::DOAP::Version reads all RDF in a distribution's "meta"
 directory and checks the distribution metadata matches the pattern:
 .
  ?uri doap:release ?rel .
  ?rel doap:revision ?ver .
 .
 Where ?uri is the URI
 "http://purl.org/NET/cpan-uri/dist/$dist/project" and ?ver is
 "$module->VERSION", as an xsd:string or plain literal.
