Building a Sustainable Metadata Workflow for Audio-visual Resources: University of Illinois Library’s Medusa Digital Preservation Repository
Abstract:
When the University of Illinois Library began development of its digital preservation
repository system, Medusa, the library found that there were many audio-visual resources
that had yet to be cataloged, i.e. inaccessible to users. In order to make resources available
to end-users and comply with Open Archival Information System (OAIS) reference model, the
library developed an ingestion package that includes descriptive metadata. The Preservation
program’s OAIS Modeling for Media Files Working Group carefully examined the currently
available best practice documents and recommendations for the cataloging of audio-visual
resources to draft levels of compliance for audio Submission Information Packages (SIPs)
and descriptive metadata. The paper introduces the detailed decision process for the
Library’s descriptive metadata standard and element set included within audio SIPs along
with their designated file formats, file specifications, and directory structures. The paper also
discusses the element-by-element comparison between PBCore and MODS, and the XMLbased
descriptive metadata creation workflow as it was applied in a recent pilot project.
