    63 Another pure Perl RDF framework. [http://search.cpan.org/~dpokorny/RDF-Core/ CPAN]. Last release: 0.51, 2007-02-19, which probably means that it's not very

    75  * Greg Williams of RDF::Trine, the other, more complete and up-to-date 
    76   RDF framework, tried to contribute to RDF::Core but was
