Please keep in mind that \s-1RDF\s0 is a graph-based data structuring format with specialized technologies such as \s-1SPARQL\s0 and triple stores. Using Catmandu::RDF to transform \s-1RDF\s0 to \s-1RDF\s0 (e.g. conversion from one \&\s-1RDF\s0 serialization to another) is possible but probably less performant than decent \s-1RDF\s0 tools. Catmandu::RDF, however, is more conventient to convert between \s-1RDF\s0 and other data formats. .SH "AVAILABLE MODULES" .IX Header "AVAILABLE MODULES" .IP "Catmandu::Exporter::RDF" 4 .IX Item "Catmandu::Exporter::RDF" Serialize \s-1RDF\s0 data (as \s-1RDF/XML, RDF/JSON,\s0 Turtle, NTriples, RDFa...) .IP "Catmandu::Importer::RDF" 4 .IX Item "Catmandu::Importer::RDF" Parse \s-1RDF\s0 data (\s-1RDF/XML, RDF/JSON,\s0 Turtle, NTriples...) or import from a \s-1SPARQL\s0 endpoint .IP "Catmandu::Fix::aref_query" 4 .IX Item "Catmandu::Fix::aref_query" Copy values of \s-1RDF\s0 data in aREF format to a new field .SH "SEE ALSO" .IX Header "SEE ALSO" This module is based on Catmandu, RDF::aREF, RDF::Trine, and \&\s-1RDF::NS\s0. .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" Copyright Jakob Vo\*8, 2014\- .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself. .SH "CONTRIBUTORS" .IX Header "CONTRIBUTORS" Jakob Vo\*8, Patrick Hochstenbach
