RDF::LDF - Linked Data Fragments client
use RDF::Trine::Store::LDF; use RDF::Trine::Store; # To use a HTTP cache: use LWP::UserAgent::CHICaching; my $cache = CHI->new( driver => 'Memory', global => 1 ); my $ua = LWP::UserAgent::CHICaching->new(cache => $cache); RDF::Trine->default_useragent($ua); 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 }
RDF::LDF implements a basic Linked Data Fragment client.
This a low level module to implement the Linked Data Fragment protocol. You probably want to use RDF::Trine::Store::LDF.
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 ]);
Return an iterator for every RDF::Trine::Statement served by the LDF server.
Returns a stream object of all bindings matching the specified graph pattern.
