METRICA, l’archivio istituzionale della produzione scientifica dell’Istituto Nazionale di Ricerca Metrologica, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ente. METRICA utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
