man RDF::Trine::Store::LDF (3): RDF Store proxy for a Linked Data Fragment endpoint

SYNOPSIS

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

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.
