The Cariniana network, managed by IBICT, is focused on developing sustainable digital preservation solutions for Brazilian universities and research centers, utilizing the LOCKSS approach since 2013. It provides digital preservation services and has established a Dataverse repository for sharing and managing research data, integrating with various systems for long-term preservation. Currently, the repository hosts data from multiple studies and is preparing for migration to Dataverse version 4.0, with ongoing efforts to create user manuals and curate data effectively.
