NAME

Test::RDF - Test RDF data for content, validity and equality

VERSION

Version 0.20

SYNOPSIS

use Test::RDF;

is_valid_rdf $rdf_string, $syntax,  'RDF string is valid according to selected syntax';
is_rdf       $rdf_string, $syntax1, $expected_rdf_string, $syntax2, 'The two strings have the same triples';
isomorph_graphs $model, $expected_model, 'The two models have the same triples'
has_subject($uri_string, $model, 'Subject URI is found');
has_predicate($uri_string, $model, 'Predicate URI is found');
has_object_uri($uri_string, $model, 'Object URI is found');
has_literal($string, $language, $datatype, $model, 'Literal is found');

EXPORT

is_valid_rdf

Use to check if the input RDF string is valid in the chosen syntax

is_rdf

Use to check if the input RDF strings are isomorphic (i.e. the same)

isomorph_graphs

Use to check if the input RDF::Trine::Models have isomorphic graphs

has_subject

Check if the string URI passed as first argument is a subject in any of the statements given in the model given as second argument.

has_predicate

Check if the string URI passed as first argument is a predicate in any of the statements given in the model given as second argument.

has_object_uri

Check if the string URI passed as first argument is a object in any of the statements given in the model given as second argument.

has_literal

Check if the string passed as first argument, with corresponding optional language and datatype as second and third respectively, is a literal in any of the statements given in the model given as fourth argument.

language and datatype may not occur in the same statement, so the test fails if they are both set. If none are used, use undef, like e.g.

has_literal('A test', undef, undef, $model, 'Simple literal');

A test for a typed literal may be done like

has_literal('42', undef, 'http://www.w3.org/2001/XMLSchema#integer', $model, 'Just an integer');

and a language literal like

has_literal('This is a Another test', 'en', undef, $model, 'Language literal');

has_uri

Check if the string URI passed as first argument is present in any of the statements given in the model given as second argument.
