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).

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)".

 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 <http://github.com/gbv/aREF>.

   *   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   *   See RDF::YAML for a similar (outdated) RDF encoding in YAML.
