"get_statements ( $subject, $predicate, $object [, $context] )"

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.

"add_statement ( $statement [, $context] )"

Adds the specified $statement to the underlying model.

"remove_statement ( $statement [, $context])"

Removes the specified $statement from the underlying model.
