NAME
       RDF::LDF - 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.
