    ->withEndpoint('http://collection.britishmuseum.org/sparql')

    ->withPrefix('crm', 'http://erlangen-crm.org/current/')

    ->withPrefix('fts', 'http://www.ontotext.com/owlim/fts#');

    ->query('

        SELECT DISTINCT ?obj

        {

            ?obj crm:P102_has_title ?title .

            ?title rdfs:label ?label .

            FILTER(STR(?label) = "Hoa Hakananai\'a")
