SYNOPSIS

  foaf_age  => '42^xsd:integer',

        ...

DESCRIPTION

aREF (another RDF Encoding Form) is an encoding of RDF graphs in form of arrays, hashes, and Unicode strings. This module implements methods for decoding from aREF data to RDF triples (RDF::aREF::Decoder) and for encoding RDF data in aREF (RDF::aREF::Encoder).

EXPORTED FUNCTIONS

decode_aref( $aref, [ %options ] )

Decodes an aREF document given as hash reference with RDF::aREF::Decoder. Shortcut for RDF::aREF::Decoder->new(%options)->decode($aref).

aref_query( $aref, [ $subject ], $query )

Experimental query function to access parts of an aREF data structure.
