from sparqlite import SPARQLClient

with SPARQLClient("https://opencitations.net/meta/sparql") as client:
    result = client.query("""
        PREFIX fabio: <http://purl.org/spar/fabio/>
        PREFIX dcterms: <http://purl.org/dc/terms/>
        PREFIX prism: <http://prismstandard.org/namespaces/basic/2.0/>

        SELECT ?article ?title ?date WHERE {
            ?article a fabio:JournalArticle ;
                     dcterms:title ?title ;
                     prism:publicationDate ?date .
