RDF::LDF(3) Linked Data Fragments client

SYNOPSIS


use RDF::Trine::Store::LDF;
use RDF::Trine::Store;
my $store = RDF::Trine::Store->new_with_config({
storetype => 'LDF',
url => $url
});
my $it = $store->get_statements();
while (my $st = $it->next) {
# $st is a RDF::Trine::Statement
print "$st\n";
}
# Or the low level modules themselves
use RDF::LDF;
my $client = RDF::LDF->new(url => 'http://fragments.dbpedia.org/2014/en');
my $iterator = $client->get_statements($subject, $predicate, $object);
while (my $statement = $iterator->()) {
# $model is a RDF::Trine::Statement
}

DESCRIPTION

RDF::LDF implements a basic Linked Data Fragment <http://linkeddatafragments.org/> client.

This a low level module to implement the Linked Data Fragment protocol. You probably want to use RDF::Trine::Store::LDF.

CONFIGURATION

url
URL to retrieve RDF from.

Experimental: more than one URL can be provided for federated search over many LDF endpoints.

    my $store = RDF::Trine::Store->new_with_config({
            storetype => 'LDF',
            url => [ $url1, $url2, $url3 ]
    });    
    # or
    my $client = RDF::LDF->new(url => [ $url1, $url2, $url3 ]);

METHODS

get_statements( $subject, $predicate, $object )
Return an iterator for every RDF::Trine::Statement served by the LDF server.
get_pattern( $bgp );
Returns a stream object of all bindings matching the specified graph pattern.
