NAME

       RDF::Trine::Store::LDF - RDF Store proxy for a Linked Data Fragment endpoint

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 query the store with SPAQRL

           use RDF::Query;
           my $model =  RDF::Trine::Model->new($store);

           my $rdf_query = RDF::Query->new(<<EOF);
           .
           .
           SPARQL
           .
           .
           EOF

           my $iter = $rdf_query->execute($model);

           while (my $s = $iter->next) {
               # $s is a RDF::Trine::VariableBinding
               print $s->value . "\n";
           }

DESCRIPTION

       RDF::Trine::Store::LDF provides a RDF::Trine::Store API to interact with a remote Linked
       Data Fragment endpoint. For details see: <http://linkeddatafragments.org/>.

METHODS

       Beyond the methods documented below, this class inherits methods from the
       RDF::Trine::Store class.

       new({ url => url })
           Returns a new RDF::Trine::Store object that will act as a proxy for the Linked Data
           Fragment endpoint accessible via the supplied $url.

           Expertimental: more than one url as an ARRAY reference can be provided for an
           federated query over many LDF endpoints.

       new_with_config( $hashref )
           Returns a new RDF::Trine::Store object configured by a hashref with the url as
           required key.

       get_statements( $subject, $predicate, $object )
           Returns a stream object of all statements matching the specified subject, predicate
           and objects.  Any of the arguments may be undef to match any value.

       get_pattern( $bgp )
           Returns an iterator object of all bindings matching the specified graph pattern.

       get_contexts
           Not supported.

       add_statement ( $statement [, $context] )
           Not supported.

       remove_statement ( $statement [, $context])
           Not supported.

       remove_statements ( $subject, $predicate, $object [, $context])
           Not supported.

       count_statements ( $subject, $predicate, $object )
           Returns a count of all the statements matching the specified subject, predicate and
           object.  Any of the arguments may be undef to match any value.

       size
           Returns the number of statements in the store.

       supports ( [ $feature ] )
           Not supported.
