Variations2: retrieving and using music in an academic setting

University music students, teachers, and researchers discover and retrieve musical works and navigate within them, then create annotations and share them with other users.

Semantics and syntax of dublin core usage in open archives initiative data providers of cultural heritage materials

This study analyzes metadata shared by cultural heritage institutions via the Open Archives Initiative Protocol for Metadata Harvesting. The syntax and semantics of metadata appearing in the Dublin Core fields creator, contributor, and date are examined. Preliminary conclusions are drawn regarding the effectiveness of Dublin Core in the Open Archives Initiative environment for cultural heritage materials

Integrating thesaurus relationships into search and browse in an online photograph collection

Purpose – Seeks to share with digital library practitioners the development process of an online image collection that integrates the syndetic structure of a controlled vocabulary to improve end‐user search and browse functionality.Design/methodology/approach – Surveys controlled vocabulary structures and their utility for catalogers and end‐users. Reviews research literature and usability findings that informed the specifications for integration of the controlled vocabulary structure into search and browse functionality. Discusses database functions facilitating query expansion using a controlled vocabulary structure, and web application handling of user queries and results display. Concludes with a discussion of open‐source alternatives and reuse of database and application components in other environments.Findings – Affirms that structured forms of browse and search can be successfully integrated into digital collections to significantly improve the users discovery experience. Establishes ways in whic...

Recommended best practices for digital image capture of musical scores

Like other complex visual articles with small details, musical scores are difficult to capture and present well in digital form. This article presents methods that can be used to reproduce detail and tone from printed scores for creating archival images, based on best practices commonly used by the library community. Capture decisions should be made with a clear idea of the purpose of the imaging project yet be flexible enough to fulfill unanticipated future uses. Options and recommendations for file formats for archival storage, Web delivery and printing of musical materials are discussed.

Promoting Shareability: Metadata Activities of the DLF Aquifer Initiative

ABSTRACT This article describes the progress of the Digital Library Federations Aquifer Metadata Working Group and demonstrates a model for the construction, application, and testing of collaboratively developed best practices for sharing metadata in the digital library environment. We set the metadata aggregation context in which the Aquifer initiative began, describe the development of a set of implementation guidelines for shareable Metadata Object Description Schema (MODS) records and their supporting documentation and tools, and discuss how this work has contributed to the understanding of what features metadata describing primary source and humanities-based resources needs in order to support scholarly use. We end with a summary of future efforts for the Aquifer initiative, and how its lessons can be applied in other metadata harvesting environments.

The CIC metadata portal: A collaborative effort in the area of digital libraries

ABSTRACT The CIC consortium includes 12 major Midwestern Universities. Their libraries have decided to share the cost of a joint project (2003-2006) aimed at better understanding the mechanisms by which emerging technologies and standards can facilitate metadata sharing and the creation of value-added services for their users. The CIC metadata portal project has performed advanced work in the area of Open Archives Initiative Protocol for Metadata Harvesting, collection-level descriptions, metadata transformation and enrichment, and practices and usability of metadata standards. It has provided an opportunity for increased collaboration between CIC academic libraries and a way to highlight the wealth of digital resources held by the participating libraries. This article describes the project and enumerates project accomplishments. The project has helped to better the way in which partner institutions share information about digital content and provide access to digital resources. Four content providers of the project highlight different aspects of the project and the practical benefits they found in the collaboration.

From Abstract to Virtual Entities: Implementation of Work-Based Searching in a Multimedia Digital Library

Libraries of digitized multimedia content provide access to virtual entities. In the case of music, where there are frequently many different performances, editions, and arrangements of a given work, the Variations2 metadata model, links all instances of a work to an abstract work record, thus yielding superior search capabilities to digital library users. This paper summarizes the motivation for addressing the music metadata problem and describes the Variations2 search user interface, which is based on our work-centric, FRBR-like metadata model.

Practical quality control procedures for digital imaging projects

Purpose – Formal quality review processes are a necessary part of any digital imaging workflow. This article illustrates a set of quality review processes implemented in the Indiana University Digital Library Programs Digital Media and Image Center.Design/methodology/approach – A methodology for automatic batch review of large numbers of images is presented, along with rationale and procedures for supplemental visual review. The initial stages of an effort to further automate and centralize image quality control at Indiana University are described.Findings – Automation of checks for objective image criteria, together with formal visual review of a sample of digitized images, is an effective means of implementing a quality review process.Originality/value – The methodologies described can be used as a model for other institutions performing digital imaging projects of any size.

Automatically Batch Loading Metadata from MARC into a Work-Based Metadata Model for Music

This article describes work done at Indiana University to “batch load” data from MARC bibliographic and authority records into the Work-based and FRBR-like Variations system. A series of experiments to iteratively refine our batch loading algorithm is described, along with details of how the algorithm identifies Works, creates relationships between entities, and maps a large amount of data from MARC into Variations records. The article closes with a discussion of the potential impact of this work on Variations project workflow and community FRBRization activities.
