Ethnomusicological Video for Instruction and Analysis Digital Archive
Jon W. Dunn and William G. Cowan
The Ethnomusicological Video for Instruction and Analysis Digital Archive (EVIADA) is a multi-year collaborative project between Indiana University and the University of Michigan, partially funded by a grant from the Andrew W. Mellon Foundation, to create a digital archive for field video recordings captured by ethnomusicology researchers. This digital archive will serve both to preserve this content for future generations of scholars and also to provide a resource to support teaching and learning in ethnomusicology and related disciplines.
The creation of EVIADA has involved a unique collaboration between ethnomusicologists, librarians, archivists, and technologists in carrying out all stages of the project, including video digitization (Figure 1), metadata creation, and system and user interface design.
It allows an ethnomusicologist who is contributing a video collection to the archive to divide that video into a hierarchy of segments (Figure 4), attach descriptions and controlled vocabulary terms to each segment, and output this information as a METS XML document incorporating MODS descriptive metadata. This METS document can then be ingested into downstream archival and delivery systems. We hope to evolve this software into a more general-purpose tool for the creation of METS documents for video objects.
We are also building a web-based user interface (Figure 5, Figure 6) on top of the Fedora digital repository system (Figure 7) and Lucene search engine (Figure 8) to allow users to search and browse video content in the collection via the descriptive metadata and annotations, making appropriate use of controlled vocabulary thesauri to improve search recall.
