=head1 NAME
Catmandu::RDF - Modules for handling RDF data within the Catmandu framework
=begin markdown

=head1 SYNOPSIS
Command line client C<catmandu>:
catmandu convert RDF --url http://dx.doi.org/10.2474/trol.7.147
--fix 'aref_query(dct_title,title)' to YAML
catmandu convert RDF --file rdfdump.nt to RDF --type turtle
See documentation of modules for more examples.
=head1 DESCRIPTION
Catmandu::RDF contains modules for handling RDF data within the L<Catmandu>
framework. RDF data is encoded/decoded in L<aREF|http://gbv.github.io/aREF/> as
implemented with L<RDF::aREF>. Please keep in mind that RDF is a graph-based
data structuring format with specialized technologies such as SPARQL and triple
stores. Using Catmandu::RDF to transform RDF to RDF (e.g. conversion from one
RDF serialization to another) is possible but probably less performant than
decent RDF tools. Catmandu::RDF, however, is more conventient to convert
between RDF and other data formats.
=head1 AVAILABLE MODULES
=over
=item L<Catmandu::Exporter::RDF>
Serialize RDF data (as RDF/XML, RDF/JSON, Turtle, NTriples, RDFa...)
=item L<Catmandu::Importer::RDF>
Parse RDF data (RDF/XML, RDF/JSON, Turtle, NTriples...) or import from a SPARQL
endpoint
=item L<Catmandu::Fix::aref_query>
Copy values of RDF data in aREF format to a new field
=back
=head1 SEE ALSO
This module is based on L<Catmandu>, L<RDF::aREF>, L<RDF::Trine>, and
L<RDF::NS>.
