K-OAr, the CLARIN Knowledge Centre for Oral Archives, intends to offer consultancy on the preservation, study, use, and reuse of oral archives. Hosted at the University of Siena’s Arezzo Campus within the Department of Philology and Literary Criticism (DFCLAM), K-OAr aims to support researchers, archivists, historians, documentalists, and ethnomusicologists by providing expert advice on digitization processes, ethical management, GDPR-compliant privacy frameworks, informed consent, metadata description, and cataloging strategies. The centre will guide professionals in adopting sustainable practices for managing and reusing oral archives.
