This article, a version of which was later published in Cataloging & Classification Quarterly 48, no. 5 (June, 2010), documents the efforts of Rutgers University Libraries to extend the Audio Engineering Society’s draft “Audio Object” schema, AESX098B (later published as AES 57-2011), for moving images and incorporate it as the technical metadata component in the RUCore metadata schema. It compares several existing and emerging audiovisual technical metadata standards (including PBCore, MPEG-7 and SMPTE standards), describes and assesses the draft AES standard and concludes with a description of the AES application profile for the Rutgers Community Repository (RUcore) and NJVid (a statewide video digital collective in New Jersey).
This paper offers a concrete technical metadata schema, based on AESX098B (later published as AES57-2011), that includes the range of elements needed to successfully document the management information needed for the preservation and use of analog and digital moving images and sound files. A serious case study, it includes the rationale behind the decision making and demonstrates the work involved in adapting and integrating a complex technical metadata schema into an existing institution’s schema. It is essential reading for metadata specialists responsible for ensuring OAIS compliant digital life cycle management of moving image and sound collections.
