The Variations2 project aims to establish a digital music library testbed system containing music in a variety of formats, involving research and development in the areas of system architecture, metadata standards, component-based application architecture, and network services. Funding for this project was provided in part by the Digital Libraries Initiative - Phase 2 program, with support from the National Science Foundation and the National Endowment for the Humanities.

    The Anatomy of a Bibliographic Search System for Music
    (2004-10) Scherle, Ryan; Byrd, Donald
    Traditional library catalog systems have been extremely effective in providing access to collections of books, films, and other material. However, they have many limitations when it comes to finding musical information, which has significantly different, and in many ways more complex, structure. The Variations2 search system is an alternative system, designed specifically to aid users in searching for music. It leverages a rich set of bibliographic data records, expressing relationships between creators of music and their creations. These records enable musicians to search for music using familiar terms and relationships, rather than trying to decipher the methods libraries typically use to organize musical items. This paper describes the design and implementation of the system that makes these searches possible.

    DLI-2: Creating the Digital Music Library: Final Report to the National Science Foundation
    (2006-09-27) Digital Library Program
    Indiana University’s Variations2 Digital Music Library project focused on three chief areas of research and development: system architecture, including content representation and metadata standards; component-based application architecture; and network services. We tested and evaluated commercial technologies, primarily for multimedia and storage management; developed custom software solutions for the needs of the music library community; integrated commercial and custom software products; and tested and evaluated prototype systems for music instruction and library services, locally at Indiana University, and at a number of satellite sites, in the U.S. and overseas. This document is the project's final report to the National Science Foundation.

    Integrating Human-Centered Design Methods from Different Disciplines: Contextual Design and PRInCiPleS
    (2004-11) Notess, Mark; Blevis, Eli
    The human-computer interaction (HCI) community has developed primarily among those trained in computer science and psychology. Design methodologies within HCI tend to address the needs and interests of those who have been trained in cognitive science, human factors, or software engineering. This paper illuminates the similarities, distinctions and opportunities existing between one of the better known HCI methodologies, Contextual Design, and an encapsulation of the oral tradition of studio-based design methods that we call PRInCiPleS. PRInCiPleS forms part of the curriculum in HCI design at the Indiana University School of Informatics. We present a case study wherein both methods were used, and we draw from that experience and our own analysis to compare and contrast HCI approaches and studio-based design approaches generally, suggesting how each may benefit from the strengths of the other and postulating a coherent integration.

    Music Learning Online: Evaluating the Promise
    (2001-11) Isaacson, Eric
    A summary of some new technologies for distance learning is provided, with illustrations of possible applications of these technologies in schools of music. Two examples of distance learning technologies under development at Indiana University are presented. Finally, a number of issues that need to be considered before adopting a distance learning approach are discussed.

    Music Representation in a Digital Music Library
    (IEEE, 2003-05) Byrd, Donald; Isaacson, Eric
    The Variations2 digital music library currently supports music in audio and score-image formats. In a future version, we plan to add music in a symbolic form. This paper describes our work defining a music representation suitable for the needs of our users.

    Predicting User Satisfaction from Subject Satisfaction
    (2003-04) Notess, Mark; Swan, Margaret B.
    In this paper, we describe work-in-progress in comparing user satisfaction ratings after user tests with ratings obtained following actual use of a digital music library software. We identify some of the variables that hamper prediction, and we reflect on the utility of surveys for predicting user/subject gaps in satisfaction.

    Three looks at users: a comparison of methods for studying digital library use
    (2003-09) Notess, Mark
    The Variations and Variations2 digital music library projects at Indiana University provide a valuable test-bed for user studies. We have used user satisfaction questionnaires, session logging, and contextual inquiry to study digital music library usage by music students. This paper describes our approach with each method and offers a comparison of cost, advantages, and disadvantages of each methods. The comparison can help digital library practitioners choose amongst or combine field-study methods based on their objectives and constraints.

    Timeliner: Building a Learning Tool into a Digital Music Library
    (2004-06) Notess, Mark; Swan, Margaret B.
    Timeliner is a pedagogical tool integrated into Variations2, the Indiana University digital music library. Timeliner enables students and instructors to create visual representations of the formal structure of musical works contained within the digital library. The tool incorporates content visualization and annotation features drawn from traditional multimedia design principles. This paper describes the Timeliner tool and its integration within Variations2. We then describe results from multi-method user studies that have informed the tool’s design. Finally, we describe our plans for improving Timeliner and integrating other pedagogical tools in Variations2. The application of these ideas is not limited to music: pedagogical tools can be integrated into digital libraries for other disciplines as well.

    Understanding and Representing Learning Activity to Support Design: A Contextual Design Example
    (2005-10) Notess, Mark
    Contextual Design is a well-defined method for gathering and representing user understanding within a coherent design process. This paper illustrates the value of Contextual Design to educational system design by describing a case study involving 14 contextual inquiry sessions that were carried out in and around the Indiana University music library, in support of designing technology for student learning. Findings are presented as diagrammatic work models, an affinity diagram, and a list of insights and design ideas. The utility of Contextual Design work modeling is assessed, and some limitations in its ability to represent learning are considered.

    V2V: A Second Variation on Query-by-Humming
    (IEEE, 2003-05) Birmingham, William P.; O'Malley, Kevin; Dunn, Jon W.; Scherle, Ryan
    Music information retrieval (MIR) systems tend to fall into two camps: that camp developing cataloging and providing advanced access systems for large collections of music and that camp developing specific query or access mechanisms. By and large, the former camp concentrates its efforts on developing large collections and integrating with existing library systems, while the latter experiments with relatively small collections that are stand alone. We have started to merge these camps by integrating Variations2, which provides access to a digitized portion of Indiana University’s vast music library, with Michigan’s VocalSearch, which provides a query-by-humming (QBH) search engine. The joint system, V2V, demonstrates how QBH can be used in connection with a large number of holdings in a real-world environment
