Transcript of Music Digital Libraries Jon Dunn IU Digital Library Program April 9, 2002.
What is a digital library? DL as collection/information system
“a collection of information that is both digitized and organized” -- Mike Lesk, NSF
“networked collections of digital text, documents, images, sounds, scientific data, and software”-- PITAC report
DL as organization: “an organization that provides the resources, including the
specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities”-- Digital Library Federation
What is a digital library? DLs extend beyond traditional libraries
Corporate documents Software/component libraries Commercial publishers Scientific datasets Geospatial datasets
IU Digital Library Program Collaborative program begun in 1998
Libraries UITS SLIS Informatics
“Dedicated to the selection, production, and maintenance of a wide range of high-quality networked resources for scholars and students at Indiana University and elsewhere”

Digital Music Library (DML) Four-year project: started October 1, 2000 Funding from Digital Libraries Initiative –
Phase 2 (DLI2) program: NSF, NEH Interdisciplinary team
Faculty: Music, Information Science, Law, Computer Science
Librarians and technologists: IU Libraries, University IT Services
IUB and IUPUI campuses
DML Project Goals Establish a digital library testbed system
for music Develop user interface applications:
music library, music instruction Conduct research: usability, metadata,
intellectual property
DML: Users and Satellite Sites University User Groups
Faculty: teaching, course design, research Students: coursework, independent study Music librarians Other library users
Satellite Sites USA, UK, and Japan Remote access Evaluation…potential for co-development
DML System Features New content formats
Sound, score image, score notation, MIDI, video Improved search capabilities
New descriptive metadata Links between objects
Easily navigate from score to sound Synchronized playback/navigation
Customization Bookmarking, annotation
DML System Features Network
Support for wide range of network technologies and bandwidths: LAN, Internet, Internet2, remote access
Access control To be determined by copyright
DML System Features Component-based architecture
Support development of applications via reusable components:

DML Version One Scheduled for Spring 2002 Features
Low level “plumbing”: data/metadata repositories
New (improved?) search and retrieval Based on new data model
Presentation/navigation of audio and scanned scores
Bookmarking
DML V1 Technical Environment Java client application / RMI servers Windows and Mac OS X client platforms Unix server QuickTime for Java, Darwin Streaming
Server IBM DB2 AT&T DjVu image compression
Features for future versions Notation Additional image, audio formats Synchronization Instructional authoring, presentation,
and lesson interface Refined, enhanced bibliographic search Integration of content-based information
retrieval tools
DML: Improving music search Traditional OPACs, integrated library
systems, cataloging practices not ideal for music Large number of works by single author Multiple works in single container Multiple roles of “authors” Importance of work: uniform titles
Many variant forms of titles Problems with Library of Congress subject
headings e.g. “Songs (High voice) with orchestra, Arranged”
Isolating / sorting by format
DML: Improving music search New data model
Better represents musical relationships Faceted classification, music thesaurus Support for structural linking
New search interface Supports disambiguation
Data Model Objects Work
Musical composition Instantiation
Recording or score of individual work Container
Entire recording, score Media Object
Sound file, image file set, notation file, etc. Contributor
Performer, conductor, composer
