    Abstract
    Nearly everyone who has searched YouTube for a favorite show, movie, news cast, or other known item, has retrieved multiple videos clips (or segments) that appear to duplicate, overlap, and relate. The work presented in this paper considers this challenge and reports on a study examining the applicability of the Functional Requirements for Bibliographic Records (FRBR) for relating varying renderings of YouTube videos. The paper also introduces the Multiple Description Coding Compression (MDC2) to extend FRBR and address YouTube preservation/storage challenges. The study sample included 20 video segments from YouTube; 10 connected with the event, Small Step for Man (US Astronaut Neil Armstrong's first step on the moon), and 10 with the 1966 classic movie, "Batman: The Movie." The FRBR analysis used a qualitative content analysis, and the MDC2 exploration was pursued via high-level approach of protocol modeling. Results indicate that FRBR is applicable to YouTube, although the analyses required a localization of the Work, Expression, Manifestation, and Item (WEMI) FRBR elements. The MDC2 exploration illustrates an approach for exploring FRBR in the context of other models, and identifies a potential means for addressing YouTube-related preservation/storage challenges.

    Abstract
    The proliferation of discipline-specific metadata schemes contributes to artificial barriers that can impede interdisciplinary and transdisciplinary research. The authors considered this problem by examining the domains, objectives, and architectures of nine metadata schemes used to document scientific data in the physical, life, and social sciences. They used a mixed-methods content analysis and Greenberg's () metadata objectives, principles, domains, and architectural layout (MODAL) framework, and derived 22 metadata-related goals from textual content describing each metadata scheme. Relationships are identified between the domains (e.g., scientific discipline and type of data) and the categories of scheme objectives. For each strong correlation (>0.6), a Fisher's exact test for nonparametric data was used to determine significance (p < .05). Significant relationships were found between the domains and objectives of the schemes. Schemes describing observational data are more likely to have "scheme harmonization" (compatibility and interoperability with related schemes) as an objective; schemes with the objective "abstraction" (a conceptual model exists separate from the technical implementation) also have the objective "sufficiency" (the scheme defines a minimal amount of information to meet the needs of the community); and schemes with the objective "data publication" do not have the objective "element refinement." The analysis indicates that many metadata-driven goals expressed by communities are independent of scientific discipline or the type of data, although they are constrained by historical community practices and workflows as well as the technological environment at the time of scheme creation. The analysis reveals 11 fundamental metadata goals for metadata documenting scientific data in support of sharing research data across disciplines and domains. The authors report these results and highlight the need for more metadata-related research, particularly in the context of recent funding agency policy changes.

    Abstract
    Assesses the current state of reference structures in OPACs in a framework defined by stagnation, progress, and future challenges. 'Stagnation' referes to the limited and inconsistent reference structure access provided in current OPACs. 'Progress' refers to improved OPAC reference structure access and reference structure possibilities that extend beyond those commonly represented in existing subject autgority control tools. The progress discussion is supported by a look at professional committee work, data modelling ideas, ontological theory, and one area of linguistic research. The discussion ends with a list of 6 areas needing attention if reference structure access is to be improved in the future OPAC environment

    Abstract
    The following investigation is a comparison between the Art and Architecture Thesaurus (AAT) and the LC Thesaurus for Graphic Materials (LCTGM), two popular sources for providing subject access to visual archives. The analysis begins with a discussion on the nature of visual archives and the employment of archival control theory to graphic materials. The major difference observed is that the AAT is a faceted structure geared towards a specialized audience of art and architecture researchers, while LCTGM is similar to LCSH in structure and aims to service the wide-spread archival community. The conclusion recognizes the need to understand the differences between subject thesauri and subject heading lists, and the pressing need to investigate and understand intellectual control of visual archives in today's automated environment.

    Abstract
    Purpose - The purpose of this paper is to examine the effect of the Helping Interdisciplinary Vocabulary Engineering (HIVE) system on the inter-indexer consistency of information professionals when assigning keywords to a scientific abstract. This study examined first, the inter-indexer consistency of potential HIVE users; second, the impact HIVE had on consistency; and third, challenges associated with using HIVE. Design/methodology/approach - A within-subjects quasi-experimental research design was used for this study. Data were collected using a task-scenario based questionnaire. Analysis was performed on consistency results using Hooper's and Rolling's inter-indexer consistency measures. A series of t-tests was used to judge the significance between consistency measure results. Findings - Results suggest that HIVE improves inter-indexing consistency. Working with HIVE increased consistency rates by 22 percent (Rolling's) and 25 percent (Hooper's) when selecting relevant terms from all vocabularies. A statistically significant difference exists between the assignment of free-text keywords and machine-aided keywords. Issues with homographs, disambiguation, vocabulary choice, and document structure were all identified as potential challenges. Research limitations/implications - Research limitations for this study can be found in the small number of vocabularies used for the study. Future research will include implementing HIVE into the Dryad Repository and studying its application in a repository system. Originality/value - This paper showcases several features used in HIVE system. By using traditional consistency measures to evaluate a semantic web technology, this paper emphasizes the link between traditional indexing and next generation machine-aided indexing (MAI) tools.
