Minnesota’s Foundations Project is a multiagency collaboration to improve access to environmental and natural resources information. The Project chose the Dublin Core metadata standard for web resources. Three studies were conducted: needs assessment, Bridges web site user interface, and usability of controlled vocabulary in Dublin Core metadata. Based on these findings and information architecture, the Project published best practice guidelines. Controlled vocabulary is important to facilitate access. This is relevant to the third study on Dublin Core metadata, which tested keyword searches of web pages to determine the effectiveness of controlled vocabulary in the Dublin Core subject tag. Central to the Best Practice Guidelines is the User Guide to Dublin Core, which offers an element-by-element understanding of the metadata schema. Current bibliographies and reports show further background work that informed the decision-making process for such important choices as metadata schema, thesaurus and thesaurus management software, search engine, and RDF/XML standards. 相似文献

BACKGROUND: Using specific examples, this paper describes the tools, methods and resources used to develop Managed Knowledge Networks (MKNs) within the NHS Scotland e-Library (http://www.elib.scot.nhs.uk). MKNs help to complete the knowledge management cycle by providing a place to share the learning and discuss the evidence for practice through combining the use of the published material (explicit knowledge) with the experience and knowledge held by individuals, communities and organizations (tacit knowledge). OBJECTIVES: First of all, this paper outlines the e-Library infrastructure, which provides an inter-operable framework to manage the published knowledge using a metadata management system; and a knowledge-sharing tool to support the development of MKNs. It then covers the various stages involved in developing an MKN: gathering and analysing information needs in a variety of ways; presenting and organizing the resources and services for the users as identified in the needs analysis; managing the tacit, personal and local knowledge. CONCLUSION: The toolkit described enables the Knowledge Services Group to take the needs of users, transcribe these into Specialist e-Libraries to provide access to the published information and to support this with accessing and sharing the knowledge of colleagues via MKNs. 相似文献

在数据化的网络时代,用户需求与图书馆服务形式向深度专业的知识化和智慧化发展。面对这种新常态,第三代图书馆服务平台的元数据管理不仅需要解决图书馆集成管理系统甚或是"下一代"图书馆服务平台受困于MARC的现状,满足资源的统一管理与业务整合,更需要考虑统一的数据建模与编码方式,实现跨类型的数据流通和知识的组织与融合。这就为元数据管理提出了新的需求,包括:完整的生命周期管理,资源类型兼容,标准规范兼容,互联网环境下的书目与规范控制,知识组织与融合。这种运用平台化思维、改变图书馆运行生态的可能性可以在FOLIO项目中看到希望。FOLIO作为以微服务架构设计的图书馆服务平台,在设计之初就定义了一个核心的微服务域--Codex。一方面,Codex作为数据注册中心和数据链接中介位于FOLIO架构的顶层,通过Codex消除不同域中数据的编码、格式和存储位置的差异,以减少域之间的交互与耦合。另一方面,Codex以BIBFRAME 2模型为基础设计了"作品-实例-单件/馆藏"的抽象数据模型,并参考DC元素设计了一套最小核心元数据元素集。Codex记录不描述资源的详细信息,只起到揭示与定位的作用。专有的业务信息或更详细的记录信息都可以通过Codex链接到相应的记录层获取。Codex作为核心的元数据管理域,将被设计成为FOLIO平台的资源链接中心、规范数据中心、跨域的全媒体资源管理入口,并通过模型中的抽象实体揭示资源间的关系。虽然现阶段仅实现了不存储自身数据的Codex Search,对关联数据的支持也不够完善,但无论是其抽象的数据模型,还是最小化的元数据方案,以及"统一记录-业务记录-正式记录"的分层描述原则,Codex都有足够的灵活性支持面向实体对象的描述与组织。 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.

Abstract Internet access and use of georeferenced public health information for GIS application will be an important and exciting development for the nation's Department of Health and Human Services and other health agencies in this new millennium. Technological progress towards public health geospatial data integration, analysis, and visualization of space-time events using the Web portends eventual robust use of GIS by public health and other sectors of the economy. Increasing Web resources from distributed spatial data portals and global geospatial libraries, and a growing suite of Web integration tools, will provide new opportunities to advance disease surveillance, control and prevention, and insure public access and community empowerment in public health decision making. Emerging supercomputing, data mining, and compression and transmission technologies will play increasingly critical roles in national emergency, catastrophic planning and response, and risk management. Web-enabled public health GIS will be guided by Federal Geographic Data Committee spatial metadata, OpenGIS Web interoperability, and GML/XML geospatial Web content standards. Public health will become a responsive and integral part of rhe National Spatial Data Infrastructure. 相似文献

This study examined research and instruction services provided by academic health sciences librarians in the United States during the COVID-19 pandemic. A total of 205 respondents (N = 205) completed an anonymous online survey about academic health sciences librarian involvement in providing research and instruction services during the global pandemic. In-depth literature searching services (86%, n = 176), curated COVID-19 research through guides (66%, n = 135), and systematic review consultations (53%, n = 109) were reported as the top three research services in demand. Librarians supported online teaching and learning at their institutions by providing online instruction for a course (92%, n = 189), facilitating access to licensed resources (73%, n = 150), and identifying open access and open educational resources (62%, n = 127). Overall, this study contributes to understanding pandemic-responsive academic library services to meet the unique needs of health sciences education and research in evolving COVID-19 pandemic information environments. 相似文献

Several factors, including the return of many public policy decisions to local communities, an increased knowledge of the information needs associated with public policy decision making, and the increasing availability of electronic means of increasing access to public policy information combine to create a set of conditions which will facilitate the development of a viable public library response to the needs associated with increasing access to this information. This article draws on several studies for data on user needs and library activity. It suggests approaches which can be used by public libraries. 相似文献

The way children's cognitive states affect how they function in digital interfaces is examined through articles published between 1989 and 2010. Children have developmental limitations, such as underdeveloped motor skills, difficulties with spelling, and trouble understanding hierarchies, classification schemes, and metadata, that make it difficult for them to find information, and challenging for adult designers to accommodate their needs. From icons to metadata to hierarchies, the best research in designing digital resources for children, (OPACs such as Pejtersen's Book House, online public libraries such as the Internet Public Library, and online collections of books such as the International Children's Digital Library), places the child user at the center, and takes an interdisciplinary and intergenerational approach. The literature indicates that research in designing for children is valuable, not only because it seeks to improve children's experience with digital resources, but also because such research translates to other marginalized users and special needs populations. 相似文献

The Plantwise knowledge bank is an open access, online resource that provides information to users involved in plant health systems in the developing world. The challenge was to deliver dependable information that could serve users with widely differing needs and understanding and to get actionable knowledge to subsistence farmers in particular. This was met by bringing together resources across CABI, particularly by supplementing core publishing capabilities with the knowledge, skills and understanding of the internationally based scientific staff and their network of collaborators. An iterative development process, with scoping, wireframes and prototype delivery, was undertaken with constant feedback from global users. Content needed to be repurposed from CABI's own databases, brought in from international partners and freshly created, and then delivered to each user in a structure that was easy to navigate and had easy‐to‐use tools to add value. The product has been widely well received and ongoing development will be guided by lessons learned and new requirements as the Plantwise programme expands. 相似文献

Abstract An external user and an academic business reference librarian collaborated to identify useful Internet resources for members of the Association of School Business Officials (ASBO). The patron provided computer skills and knowledge of the information needs of school business officials. The librarian provided knowledge of resources and access to the Internet. This service commitment to an “outsider” who was not part of the primary user population directly improved the librarian' s working relationships with her primary user population and improved her ability to serve her professional association. She also gained understanding of the information needs and changing role of school business officials. This paper describes the collaborative effort and the results, and focuses on the development process used to create an Internet site. 相似文献

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice. 相似文献
