AtteanX::Store::SPARQL - Attean SPARQL store
my $store = Attean->get_store('SPARQL')->new(endpoint_url => $url);
This implements a simple immutable triple store, which simply allows programmers
to use Attean facilities to query remote SPARQL endpoints.
This distribution also brings a corresponding AtteanX::Model::SPARQL, which
allows query plans to be made, and a AtteanX::Plan::SPARQLBGP plan class,
which contains a rudimentary cost estimate that attempts to avoid sending
Cartesian joins to remote endpoints if possible.
- The URL of a remote SPARQL endpoint. Will be coerced into a
URI object, so it may be set as a string or whatever. Required
- An LWP::UserAgent object to use for remote queries. Will be
set to a reasonable default if not supplied.
- Method to query the remote endpoint, as required by
- Reimplemented using an aggregate query for greater
- "get_sparql($sparql, [ $ua ])"
- Will submit the given $sparql query to the above
"endpoint_url" attribute. Optionally, you may pass an
LWP::UserAgent, if not it will use the user agent set using the
"ua" method. Will return an iterator with the results if the
request is successful.
