    Abstract
    Metadata quality of digital resources in a repository is an issue directly associated with the repository's efficiency and value. In this paper, the subject of metadata quality is approached by introducing a new conceptual framework that defines it in terms of its fundamental components. Additionally, a method for assessing these components by exploiting structural and semantic relations among the resources is presented. These relations can be used to generate implied logic rules, which include, impose or prohibit certain values in the fields of a metadata record. The use of such rules can serve as a tool for conducting quality control in the records, in order to diagnose deficiencies and errors.

    Abstract
    Collection-level metadata has the potential to provide important information about the features and purpose of individual collections. This paper reports on a content analysis of collection records in an aggregation of cultural heritage collections. The findings show that the free-text Description field often provides more accurate and complete representation of subjects and object types than the specified fields. Properties such as importance, uniqueness, comprehensiveness, provenance, and creator are articulated, as well as other vital contextual information about the intentions of a collector and the value of a collection, as a whole, for scholarly users. The results demonstrate that the semantically rich free-text Description field is essential to understanding the context of collections in large aggregations and can serve as a source of data for enhancing and customizing controlled vocabularies.

    Abstract
    Cornell University Library (CUL) has developed a largely automated method for providing title-level catalog access to electronic journals made available through aggregator packages. CUL's technique for automated e-journal record creation and maintenance relies largely on the conversion of externally supplied metadata into streamlined, abbreviated-level MARC records. Unlike the Cooperative Online Serials Cataloging Program's recently implemented aggregator-neutral approach to e-journal cataloging, CUL's method involves the creation of a separate bibliographic record for each version of an e-journal title in order to facilitate automated record maintenance. An indexed local field indicates the aggregation to which each title belongs and enables machine manipulation of all the records associated with a specific aggregation. Information encoded in another locally defined field facilitates the identification of all of the library's e-journal titles and allows for the automatic generation of a Web-based title list of e-journals. CUL's approach to providing title-level catalog access to its e-journal aggregations involves a number of tradeoffs in which some elements of traditional bibliographic description (such as subject headings and linking fields) are sacrificed in the interest of timeliness and affordability. URLs (Uniform Resource Locators) and holdings information are updated on a regular basis by use of automated methods that save on staff costs.

    Abstract
    This article describes a pilot study undertaken to test the benefits of the digitized Content and Index pages of books and content pages of journal Issues in providing subject access to documents in a collection. A partial digitization strategy is used to fossick specific information using the alternative subject access fields in bibliographic records. A pilot study was carried out to search for books and journal articles containing information on "Leadership., "Women Entrepreneurs., "Disinvestment. and "Digital preservation. through normal procedu re and based on information stored in MARC 21 fields 653, 505 and 520 of the bibliographic records in the University of Mumbai Library. The results are compared to draw the conclusions.

    Abstract
    Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

    Abstract
    Completeness of metadata is one of the most essential characteristics of their quality. An incomplete metadata record is a record of degraded quality. Existing approaches to measure metadata completeness limit their scope in counting the existence of values in fields, regardless of the metadata hierarchy as defined in international standards. Such a traditional approach overlooks several issues that need to be taken into account. This paper presents a fine-grained metrics system for measuring metadata completeness, based on field completeness. A metadata field is considered to be a container of multiple pieces of information. In this regard, the proposed system is capable of following the hierarchy of metadata as it is set by the metadata schema and admeasuring the effect of multiple values of multivalued fields. An application of the proposed metrics system, after being configured according to specific user requirements, to measure completeness of a real-world set of metadata is demonstrated. The results prove its ability to assess the sufficiency of metadata to describe a resource and provide targeted measures of completeness throughout the metadata hierarchy.

    Abstract
    With the transition from cartographic materials to spatial information the nature and amount of access data for the library field is changing. Besides bibliographic data there exists now a range of metadata, each kind for specific purposes within specific user fields. To define their relation to each other they have been put into a diagram. Through the Resource Description Framework these should all be available through a common interface for Internet-searching. To prevent confusion spatial metadata is defined. Spatial metadata introduces new elements to descriptions with new application possibilities.

    Abstract
    Describes an approach to retrieving environmental sciences information on the Internet using metadatabases. an inf-sheet is created in a flat file system for each resource. The contents of theses sheets are structured by different fields which hold different types of information. 2 classes of information can be distinguished: information describing the content of a resource, which is searchable, and information which links to the resources (URL). A rough automated selection is performed, humans analyze the pre selected resources, and a final selection and indexing is carried out. An algorithm which controle the validity of the meta information is implemented. Describes 2 implemented examples, the Register of Ecological Models and the Metadatabase of Internet Resources

    Abstract
    The historical interweaving of evolving trends and applications in metadata and bibliographic control seems largely absent from the literature. To address this apparent gap in perspective, we trace some historic and more recent developments related to each, and speculate on future directions. Cataloguing rules are ancestors to the current lineage of bibliographic standards. Metadata schemas have been developed to meet the needs of particular fields or domains and to support a variety of functions related to resource discovery. While differences between the tools of bibliographic control and of metadata application still remain, the similarities have become sufficient to warrant a confluence in terminology and definition. While internationally determined codes and standards have fostered the goal of universal bibliographic control, syntactic structures, semantic element sets, transmission protocols, cross-schema mappings, and metadata harvesting tools have been instrumental to realizing the concept of interoperability.

    Abstract
    This study examines subject and genre representation in metadata that describes information resources created for children and young adult audiences. Both quantitative and limited qualitative analyses were applied to the analysis of WorldCat records collected in 2021 and contributed by the Children's and Young Adults' Cataloging Program at the US Library of Congress. This dataset contains records created several years prior to the data collection point and edited by various OCLC member institutions. Findings provide information on the level and patterns of application of these kinds of metadata important for information access, with a focus on the fields, subfields, and controlled vocabularies used. The discussion of results includes a detailed evaluation of genre and subject metadata quality (accuracy, completeness, and consistency).
