Abstract

The Program for Cooperative Cataloging's 2018–21 strategic plan includes as one of its goals to “expand [the] use of linked data value vocabularies to augment, and where feasible to replace, existing metadata practices”. This paper sets out the reasons for pursuing this goal and considers some of the implications for MARC cataloging practice.  相似文献

ABSTRACT. Institutional repositories (IRs) provide storage and access to digitally produced scholarship. In order to improve storage and access to these materials, it is important for the creators to describe the contents adequately. Following generally accepted best practices in terms of file formats is encouraged, as is providing basic metadata about the content of the items. Some of the benefits of utilizing IRs include the provision of unique identifiers for digital projects and files, institutional commitment to preserving the files, and increased access through metadata protocols. Collaboration between creators and librarians is encouraged to ensure that standards are followed when appropriate, and that metadata is of the highest quality to ensure good preservation and access to the content.  相似文献

An institutional repository is a system for dissemination and stewardship of the intellectual life and scholarship of an institution. It has become a new way for the institutions to contribute to the broader world of scholarship (Giesecke, 2011 Giesecke, J. (2011). Institutional repositories: Keys to success. Journal of Library Administration, 51(5–6), 529542. Retrieved January 3, 2013, from http://digitalcommons.unl.edu/libraryscience/255[Taylor & Francis Online] [Google Scholar]). In spite of the global recognition of institutional repositories as an open access scholarly communication channel, institutional repositories are still struggling with the problem of non-participation from contributors in developing countries like India. This study conveys the results of a survey conducted at a minority university of India. The study is an expression of the opinion of 542 faculty members and research scholars pertaining to the possible implications of institutional repositories on their professional and publishing practices. The study is undertaken to: Determine the level of awareness of institutional repository among contributors; identify the reasons for participation and non-participation of contributors; examine the implications of institutional repository on contributors professional and publishing practices; analyze the major obstacles/hindrances in the growth of an institutional repository; and suggest measures for better implementation and development of an institutional repository in future. With the help of the statistical techniques such as chi-square test and weighted mean the study resulted that the majority of the contributors are well aware about the concept of institutional repository, the majority of contributors have not deposited in an institutional repository so far, long term preservation of research materials is the first ranked reason for participation in an institutional repository, copyright and plagiarism concern is the main reason behind contributors’ non-participation in institutional repository, increased accessibility of research output is the major implication of the institutional repository on contributors professional practices, saved cost of publishing in a journal is the biggest implication of institutional repository on contributors publishing practices, and contributors demand more control on ownership, access and security in future for an institutional repository. This article is aimed at the institutions that report low-use and low-deposit repositories. It may be used to convince the contributors about the value of institutional repositories, importance of participating in an institutional repository and possible implications on their professional and publishing practices. The study is also intended at the management of the institutions to take notice of the contributors’ demands for future participation and develop policies accordingly for removing major barriers in the growth of institutional repositories and improving contributions and quality of content in the institutional repositories.  相似文献

ABSTRACT

The University of South Florida Libraries house and provide access to a collection of cultural heritage and 3D digital models. In an effort to provide greater access to these collections, a linked data project has been implemented. A metadata schema for the 3D cultural heritage objects which uses linked data is an excellent way to share these collections with other repositories, thus gaining global exposure and access to these valuable resources. This article will share the process of building the 3D cultural heritage metadata model as well as an assessment of the model and recommendations for future linked data projects.  相似文献

ABSTRACT. This article looks at selected digital library projects in the Czech Republic, with a focus on two main domains of activity: digital preservation of cultural heritage, and providing digital access to scholarship through institutional repositories. With regard to digitization of national cultural heritage, the Czech Republic, largely through the leadership of the National Library, has established itself as one of the most active countries in the region. With regard to providing access to Czech research and scholarship, although there is quite a bit of interest among research institutions and universities, institutional repositories are currently in the exploratory stage and have not yet been widely implemented. Copyright laws are repeatedly cited by Czech librarians as one obstacle to improving access to digital resources in both spheres of activity.  相似文献

In this rejoinder, I argue that explanations made in Croucher (2015) [Further development of integrated threat theory and intergroup contact: A reply to Aberson (2015). Communication Monographs] for odd results are not theoretically relevant, represent highly unlikely outcomes inconsistent with the reporting in Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62], and are likely not the result of a unique sample or target. First, I demonstrate that arguments regarding negative contact are not applicable to the present work as Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62] measured positive contact. Next, I note that arguments regarding use of pairwise deletion are theoretically possible, but practically would represent extreme situations that suggest substantial issue with the dataset. I also note that Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62] made no mention of the amount of missing data or approaches used to deal with missing values. Finally, I highlight that the use of an adult sample and Muslim targets is by no means unique within the integrated threat literature and that findings from studies using similar samples and targets remain at odds with Croucher (2013) [Integrated threat theory and acceptance of immigrant assimilation: An analysis of Muslim immigration in Western Europe. Communication Monographs, 80, 46–62].  相似文献

Digital repositories require good metadata, created according to community-based principles that include provisions for interoperability. When metadata is of high quality, digital objects become sharable and metadata can be harvested and reused outside of the local system. A sample of U.S.-based repository administrators from the OpenDOAR initiative were surveyed to understand aspects of the quality and creation of their metadata, and how their metadata could improve. Most respondents (65%) thought their metadata was of average quality; none thought their metadata was high quality or poor quality. The discussion argues that increased strategic staffing will alleviate many perceived issues with metadata quality.  相似文献

Previous papers on grey literature by the authors have described (1) the need for formal metadata to allow machine understanding and therefore scalable operations; (2) the enhancement of repositories of grey (and other) e-publications by linking with CRIS (Current Research Information Systems); (3) the use of the research process to collect metadata incrementally reducing the threshold barrier for end-users and improving quality in an ambient GRIDs environment. This paper takes the development one step further and proposes “intelligent” grey objects. The hypothesis is in 2 parts: (1) that the use of passive catalogs of metadata does not scale (a) in a highly distributed environment with millions of nodes and (b) with vastly increased volumes of R&D output grey publications with associated metadata; (2) that a new paradigm is required that (a) integrates grey with white literature and other R&D outputs such as software, data, products and patents (b) in a self-managing, self-optimizing way and that this paradigm manages automatically curation, provenance digital rights, trust, security and privacy. Concerning (1) existing repositories provide catalogs; harvesting takes increasing time ensuring non-currency. The end-user expends much manual effort/intelligence to utilize the results. The elapsed time of (1) the network (2) the centralized (or centrally controlled distributed) catalog server searches (3) end-user intervention becomes unacceptable. Concerning (2) there is no paradigm currently known to the authors that satisfies the requirement. Our proposal is outlined below. Hyperactive combines both hyperlinking and active properties of a (grey) object. Hyperlinking implies multimedia components linked to form the object and also external links to other resources. The term active implies that objects do not lie passively in a repository to be retrieved by end-users. They “get a life” and the object moves through the network knowing where it is going. A hyperactive grey object is wrapped by its (incrementally recorded) formal metadata and an associated (software) agent. It moves through process steps such as initial concept, authoring, reviewing and depositing in a repository. The workflow is based on the rules and information in the corporate data repository with which the agent interacts. Once the object is deposited, the agent associated with it actively pushes the object to the end-users (or systems) whose metadata indicate interest or an obligation in a workflowed process. The agents check the object and user (or system) metadata for rights, privacy, security parameters, and for any charges and assure compatibility. Alternatively the object can be found passively by end-user or system agents. The object can also associate itself with other objects forming relationships utilising metadata or content. Declared relationships include references and citations; workflowed relationships include versions and also links to corporate information and research datasets and software; inferenced relationships are discovered relationships such as between documents by different authors developed from an earlier idea of a third author. Components of this paradigm have been implemented to some extent. The challenge is implementing—respecting part two of the hypothesis—the integration architecture. This surely is harnessing the power of grey.

Analysis of a survey of the types and extent of tools and techniques related to semi-automatic metadata generation applied in real-world library settings indicates that practical applications in libraries seem to be at an incipient stage. More than half (n  = 149, 52.5%) of the survey participants (n  = 285) specify that semi-automatic metadata generation has not been utilized for metadata creation and management in their libraries. This figure becomes even higher when adding the response “don't know,” constituting an additional 13.7%. The results of the survey also show that the semi-automatic metadata generation tools described by participants mostly concern metadata format conversion (38.6%) and metadata templates and forms (27%) for populating certain metadata values. Complex tools and the generation and extraction of metadata directly from the content and context of the digital objects are rarely applied in libraries. This indicates that more research is needed on the development of automatic metadata generation for semantic metadata in usable and practical settings.  相似文献

Crowdsourced metadata available in iTunes is too often insufficient or even incorrect for classical music recordings. Listeners find themselves frustrated when the only options iTunes provides are illogical. What we need is a group of professionals who are experts in music and information organization to clean things up. Enter the Music Library Association. The author proposes that this national group with ten regional chapters divide the work of providing improved metadata for classical recordings, using an open source program such as freedb. Working with Gracenote, individual music librarians could also correct existing data and reduce instances of a user encountering poor information.  相似文献
