    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.
