Digital Archival Objects (DAOs) are electronic representations of archival materials like files, images, and audiovisual content. The Archives Hub uses standard tags like <dao> and <daogrp> to display DAOs within finding aid descriptions. Institutions maintain DAOs on their own servers and provide persistent URLs, while the Archives Hub follows standard practices for embedding and linking content. DAOs should have descriptive captions and institutions should consider file sizes and formats that are appropriate for online access.
