VERSION

SYNOPSIS
Command Line Tools
% jsonld-expand input.jsonld
Prints the JSON-LD 1.1 expansion of the data in input.jsonld to standard out.
% jsonld-compact input.jsonld
Prints the JSON-LD 1.1 compaction of the data in input.jsonld to standard out.
% jsonld-nq input.jsonld
Prints the JSON-LD 1.1 deserialization of the data in input.jsonld to standard out in the N-Quads format.
JSON-LD Perl API
use v5.14;
use JSON qw(decode_json);
use JSONLD;
my $infile = 'test.jsonld';
open(my $fh, '<:utf8', $infile) or die $!;
my $content = do { local($/); <$fh> };
my $data = decode_json($content);
my $jld = JSONLD->new();
my $expanded = $jld->expand($data);
DESCRIPTION
This module implements part of the JSON-LD 1.1 standard for manipulating JSON data as linked data.
This version provides full support for the JSON-LD 1.1 "Expansion" and "toRdf" transformations (the latter primarily being useful through a subclass of JSON-LD, such as that provided by LAtteanX::Parser::JSONLD). Partial support for the "Compaction" transformation is provided, but it contains many known deficiencies. Full support for "Compaction" may be forthcoming in a future release. No other JSON-LD transformation are supported at this time.
METHODS
expand( $data )
Returns the JSON-LD expansion of $data.
to_rdf( $data )
Returns the dataset generated by turning the JSON-LD expansion of
$data into RDF.
Note: this method must be called on a JSONLD subclass which
implements the RDF-related methods listed below.
See AtteanX::Parser::JSONLD
for an implementation of such a subclass.
