    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);

DESCRIPTION¶

aREF (another RDF Encoding Form <http://gbv.github.io/aREF/>) 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).

WARNING¶

aREF has been an attempt to solve problems that meanwhile have largely been solved by JSON-LD <https://json-ld.org/>. Despite aRef having its own benefits, please consider using a more established technology (JSON-LD) instead!
