# JSONLD ## A Perl toolkit for interacting with JSON-LD data. ## VERSION This document describes JSONLD version 0.004_01. ## 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 L). 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](https://metacpan.org/pod/AtteanX::Parser::JSONLD) for an implementation of such a subclass. * `default_graph()` * `new_dataset()` * `new_triple($s, $p, $o)` * `new_quad($s, $p, $o, $g)` * `new_iri($value)` * `new_graphname($value)` * `new_blank( [$id] )` * `new_lang_literal($value, $lang)` * `new_dt_literal($value, $datatype)` * `add_quad($quad, $dataset)` ## BUGS Please report any bugs or feature requests to through the GitHub web interface at . ## SEE ALSO * * [AtteanX::Parser::JSONLD](https://metacpan.org/pod/AtteanX::Parser::JSONLD) * * * ## AUTHOR Gregory Todd Williams ## COPYRIGHT Copyright (c) 2019--2020 Gregory Todd Williams.
