NAME RDF::aREF - Another RDF Encoding Form SYNOPSIS use RDF::aREF; my $rdf = { _id => 'http://example.com/people#alice', foaf_name => 'Alice Smith', foaf_age => '42^xsd_integer', foaf_homepage => [ { _id => 'http://personal.example.org/', dct_modified => '2010-05-29^xsd_date', }, 'http://work.example.com/asmith/', ], foaf_knows => { dct_description => 'a nice guy@en', }, }; decode_aref( $rdf, callback => sub { my ($subject, $predicate, $object, $language, $datatype) = @_; ... } ); my @lastmod = aref_query( $rdf, 'foaf_homepage.dct_modified^' ); my $model = RDF::Trine::Model->new; decode_aref( $rdf, callback => $model ); print RDF::Trine::Serializer->new('Turtle')->serialize_model_to_string($model); my $model = RDF::Trine::Model->new; RDF::Trine::Parser->parse_url_into_model($url, $model); my $aref = encode_aref $model; DESCRIPTION aREF (another RDF Encoding Form ) is an encoding of RDF graphs in form of arrays, hashes, and Unicode strings. This module provides methods for decoding from aREF data to RDF triples (RDF::aREF::Decoder), for encoding RDF data in aREF (RDF::aREF::Encoder), and for querying parts of an RDF graph (RDF::aREF::Query). EXPORTED FUNCTIONS The following functions are exported by default. decode_aref( $aref [, %options ] ) Decodes an aREF document given as hash reference with RDF::aREF::Decoder. Equivalent to "RDF::aREF::Decoder->new(%options)->decode($aref)". encode_aref( $rdf [, %options ] ) Create a new RDF::aREF::Encoder and construct an aREF subject map with RDF triples given as RDF::Trine::Model, as RDF::Trine::Model::Iterator or as hash reference with RDF/JSON format, as returned by method "as_hashref" in RDF::Trine::Model. *experimental* aref_query( $graph, [ $origin ], $query ) Query parts of an aREF data structure. See RDF::aREF::Query for details. aref_query_map( $graph, [ $origin ], $query_map ) Map parts of an aREF data structure to a flat key-value structure. SEE ALSO * aREF is specified at . * See Catmandu::RDF for an application of this module. * Usee RDF::Trine for more elaborated handling of RDF data in Perl. * See RDF::YAML for a similar (outdated) RDF encoding in YAML.
