1	EVIA Digital Archive Project Jon W. Dunn and William G. Cowan Digital Library Program Indiana University DLF Fall Forum 27 October 2004
2	EVIA Digital Archive Project EVIA: Ethnomusicological Video for Instruction and Analysis Partnership between Indiana University and University of Michigan Funding support from the Andrew W. Mellon Foundation
3	Project Background Originated with ethnomusicologists Need for infrastructure to support ethnomusicology field video Two goals: Provide means for archiving video Provide access for use in teaching/learning and research
4	Project Timeline Planning Phase 2001-2002 Three meetings bringing together ethnomusicologists, archivists, librarians, IT professionals, video professionals, intellectual property experts Development Phase 2003-2005 Goal: Build tools and set up infrastructure to digitize, annotate, and provide access to total of 150 hours of video from 15 contributors
5	Focus of This Presentation Digitization, annotation process Tools for segmentation/annotation Preview of tools for access Future directions

7	Application Development Environment Video Segmentation and Annotation application Developed as Java application With Borland JBuilder Using an Oracle 9.2 database Runs in Microsoft Windows Uses QuickTime and QuickTime for Java
8	Metadata Standards and Schemas Metadata is collected by the application and stored as XML documents METS 1.3 Schema Structural metadata (METS structmap) Container for descriptive and technical metadata Pointers to digital files MODS 3.0 Schema Collection descriptive metadata Video segment descriptive metadata
9	Creating the Digital Archive Original tape from contributor Variety of formats, both analog and digital Dub to Digibeta tape Digibeta tape to 50 Mbps MPEG-2 digital file 50 Mbps digital file transcoded to MPEG-4 digital file 50 Mbps digital file stored in IU’s Massive Data Storage System Digibeta tape stored at IU Archives of Traditional Music (ATM) If collector chooses, original tape may be stored at ATM as well
10	Creating the Digital Archive: Some Statistics Size of 50 Mbps digital master file 10 - 15 gigs per hour of video 100 – 200 gigs per collection Effort to create transcoded file 8 hours per hour of video Includes: dubbing digibeta tape, MPEG-2 encoding, checksum generation, transmission and transcoding
11	EVIA Digital Archive Summer Institute 2004 June 9 – 19, 2004 at Indiana University Collaboration of ethnomusicologists, technicians, programmers, catalogers Contributions of 10 hours of video from 11 ethnomusicologists spanning 4 decades of field work Ethnomusicologists segmented and annotated digital video, participated in workshops, presented their results
12	EVIA Digital Archive Controlled Vocabulary Predefined categories chosen by ethnomusicologists and catalogers Predefined values based on authority sources chosen by catalogers Predefined values stored in tables in Oracle database and available to be selected in annotation application As needed, new values would be added by catalogers during the Summer Institute
13	EVIA Digital Archive Controlled Vocabulary Language Culture Group Geographic Location Genre Instruments Venue Theme Performance Type Participant and Participant Role
14	EVIA Digital Archive Controlled Vocabulary Authorities Library of Congress Subject Headings MARC Code Lists for Relators Getty Art and Architecture Thesaurus Getty Thesaurus of Geographic Names

16	Video Segmentation Hierarchy
17	Creating Video Segments and Annotations Creation of initial METS XML file for each ethnomusicologist Basic Data Points to Transcoded Files on file server Event segmentation Continuous video stream of all digitized video for the contributor Contributor Segments continuous video stream into significant events.
18	Creating Video Segments and Annotations Contributor now segments events into scenes and actions Open an Event Segment as Scene Descriptive text Controlled vocabulary Segment Scene into Actions
19	EVIA Digital Archive Demo EVIA Digital Archive Demo
20	EVIA Digital Archive Current Development Web access to annotated video segments EVIA Digital Archive Web Storing and Retrieving XML Documents from Oracle 9.2 XDB (native XML database) Indexing, searching and retrieving XML from the XDB
21	Lessons (Being) Learned A lot of effort to create digital video Need for clearly defined production processes and procedures Compromises on video formats Technical metadata collection and storage Evolving working relationships between scholars, librarians, archivists, technologists, video engineers
22	Possible Future Directions Tools and Technology Open Source METS/MODS Video Segmentation/Annotation Tool Field version of Segmentation/Annotation Tool Further work with native XML databases Integration into teaching/learning environments, course management systems Sustainability Examining options
