Sounding It Out: Sharing and Disseminating Audio-Visual Data

Presenter 1
Mus Ahmet and Louise Corti

Increasingly data archives are confronting new kinds of media. Qualitative data is traditionally captured as an audio source, and increasingly visually, yet the sharing of that data can be problemetic. Format standards, storage capacity and consent to share have been the main barrier. The UKDA currently delivers audio in MP3 format via authenticated web-based downloads, but has been investigating enhanced delivery solutions and long term open storage formats. The goal being to deliver a flexible open-source streaming media format with rich metadata content. The precise description and representation of audio/visual data is also challenge. UKDA has been working on metadata schema for complex multi-media collections – including using METS and those for relating text and audio-visual. Item level description for complex multi media collections adds power to the data. UKDA has been leading some exciting developments in: minimising data storage requirements whilst simultaneously maximising audio quality; and representing audio-visual sources using hypermedia and FEDORA-based systems. This paper will provide an overview and discussion of these developments and consider future best practice and guidance.
