The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right. 相似文献

ABSTRACTToday's learners operate in digital environments which can be largely navigated with no human intervention. At the same time, libraries spend millions and millions of dollars to provide access to content which our users may never know is available to them. Through the Open SESMO (Search Engine & Social Media Optimization) database project, Montana State University (MSU) Library applied search engine optimization and structured data with the Schema.org vocabulary, linked data models and practices, and social media optimization techniques to all the library's subscribed databases. Our research shows that Open SESMO creates significant return-on-investment with substantial increased traffic to our paid resources by our users as evidenced through analytics and metrics. In the core research of the article, we take a quantitative look at the pre/post results to assess the Open SESMO method and its impact on organic search referrals and use of the collection analyzing data from three distinct fall semesters. Returns include demonstrated library value through database recommendations, connecting researchers to subject librarians, and increased visitation to our library's paid databases with growth in organic search referrals, impressions, and click-through rates. This project offers a standard and innovative practice for other libraries to employ in surfacing their paid databases to users through the open web by applying structured and linked data methods. 相似文献

This study examines factors that account for the success of traditional media's Internet spin-offs in terms of attracted users and the page impressions they generate. Based on empirical data pertaining to the German market, we derive a model explaining online success through the reach of the parent offline medium regarded as given, and the varying degrees to which 5 key levers are employed by the Web site management. The analysis demonstrates that differences in offline reach, considered as one of the main assets of traditional media to leverage online, account for only about a third of the differences in the number of users and for about a tenth of the differences in page impressions. Although the argument for the importance of offline reach (i.e., the brand equity to be leveraged online) is theoretically convincing, this analysis illustrates that the large differences in page impressions and the number of users still are predominantly due to the considerable disparities in manageable levers, inherently independent of offline reach. By benchmarking these levers, the analysis elucidates that managers of online spin-offs are far from maximizing online success. 相似文献

The United States’ National Oceanic and Atmospheric Administration (NOAA) operates over one hundred observing systems and numerical models providing information and forecasts about the planetary environment from the bottom of the ocean to the surface of the Sun. Collected NOAA data constitute an irreplaceable resource that must be well-documented, discoverable, accessible, and preserved for future use. Good data management should therefore be part of NOAA's core business practices, and employees and leadership should be aware of their roles and responsibilities in this arena. NOAA has developed an Environmental Data Management (EDM) Framework document that discusses Principles, Governance, Resources, Standards, Architecture, Assessment, and the Data Lifecycle, and which also enumerates specific recommendations. The NOAA EDM Committee has issued Directives pertaining to data management planning, archiving, data access, metadata, and other topics. A Data Catalog has been established, and a project to assign persistent, citable identifiers to archival data is well underway. Numerous groups at NOAA are performing technical work related to data access, usability, and preservation.The purpose of this article is to describe these documents and activities in order to share our experiences and to provide guidance and encouragement for improved data management practices and processes at other organizations. 相似文献

This work analyses the perception and practice of sharing, reusing, and facilitating access to research data in the field of food science and technology. The study involved the coordination of a focus group discussion and an online survey, to understand and evince the behaviour of researchers regarding data management in that field. Both the discussion group and the survey were performed with researchers from several institutes of the Spanish National Research Council. The lack of a data sharing culture, the fear of being scooped, and confusion between the concepts of the working plan and the data management plan were some of the issues that emerged in the focus group. Respondents' previous experience with sharing their research data has been mainly in the form of appendices to peer‐reviewed publications. From the survey (101 responses), the most important motivations for publishing research data were found to be facilitating the reproducibility of the research, increasing the likelihood of citations of the article, and compliance with funding body mandates. Legal constraints, intellectual property, data ownership, data rights, potential commercial exploitation, and misuse of data were the main barriers to publishing data as open data. Citation in publications, certification, compliance with standards, and the reputation of the data providers were the most relevant factors affecting the use of other researchers' data. Being recent or recently updated, well documented, with quality metadata and ease of access were the most valued attributes of open research data. 相似文献

Points of convergence: seamless long-term access to digital publications and archival records at library and archives Canada 总被引：1，自引：0，他引：1
In 2004, Canada’s national library and national archives merged to form Library and Archives Canada (LAC). LAC has become more than the sum of its parts, creating synergies between library and archives collections and services, realizing efficiencies and satisfying user demands for seamless access to all holdings. LAC has already created and launched Fed Search, an online search tool that provides clients with single-search access to library, archives and online collections. LAC is in the process of building a Trusted Digital Repository that will combine ingest, preservation, management and dissemination services for archives and library collections. 相似文献

Open data is information that is provided by public entities to be accessed and reused. Publishing open data is an excellent way to improve an organization’s transparency and provide insight into the value of the organization. Libraries are uniquely positioned to assist their patrons in the use of open data by making them aware of it and helping them access and use it. This article provides a short history of open data and explores ways that library trailblazers are already using open data as well as contributing open data for others to use. Getting started with open data involves identifying key open data resources such as data.gov, identifying library information that would be beneficial to publish, and creating programs that provide digital literacy training and create opportunities for patrons to engage with open data in new and creative ways. 相似文献

This article presents a multifarious examination of natural resources and environmental scientists' adventures navigating the policy change toward open access and cultural shift in data management, sharing, and reuse. Situated in the institutional context of Virginia Tech, a focus group and multiple individual interviews were conducted exploring the domain scientists' all-around experiences, performances, and perspectives on their collection, adoption, integration, preservation, and management of data. The results reveal the scientists' struggles, concerns, and barriers encountered, as well as their shared values, beliefs, passions, and aspirations when working with data. Based on these findings, this study provides suggestions on data modeling and knowledge representation strategies to support the long-term viability, stewardship, accessibility, and sustainability of scientific data. It also discusses the art of curation as creative scholarship and new opportunities for data librarians and information professionals to mobilize the data revolution. 相似文献

Students and scholars can take full advantage of Open Access journals only if libraries make them available through mechanisms that are familiar to patrons. This study examines the extent to which American liberal arts colleges have provided access to Open Access journals through their journal title lists (Serials Solutions, Ex Libris, etc.) and their online public access catalogs (OPACs). While 57 percent of the colleges provide access to at least 90 percent of the journals in our sample, 20 percent of the colleges provide access to fewer than 20 percent of the journals. Large and high-impact journals are especially likely to appear in libraries' catalogs and journal lists. There is no systematic trend by publication fee status or country of publication, however. The study concludes with a discussion of the strategies libraries can use to select Open Access journals and add them to their collections. 相似文献

Abstract With the transformation of the card catalog into the online public access catalog came the expectation of its increased functionality. For the most part, today's online catalogs perform an expanded list of tasks quite effectively. Bibliographic utilities, system vendors, and individual libraries continue to improve bibliographic retrieval by providing new and better services through the catalog. In spite of these improvements, many observers believe that online catalogs have reached their maturity. Today's information environment includes a wealth of material to which online catalogs cannot provide universal and up-to-date access. Increasingly, librarians are turning to federated searching portal applications to find a means of managing the flood of digital information that threatens to engulf users. This chapter describes essential functionality of such tools, suggesting directions and strategies for improving them. The author concludes that, while the online catalog will continue to function as the principal tool for access control of the library's physical collections, the federated searching portal will ultimately serve as the library's principal Web gateway to digital resources. 相似文献

This paper presents a benchmark proposal for the Open Government and its application from the open data perspective using data available on the U.S. government's open data portal (data.gov). The benchmark is developed over the adopted Open Government conceptual model, which describes Open Government through data openness, transparency, participation and collaboration. Resulting in two measures, that is, one known as the e-government openness index (eGovOI) and the other Maturity, the benchmark indicates the progress of government over time, the efficiency of recognizing and implementing new concepts and the willingness of the government to recognize and embrace innovative ideas. 相似文献

Scans of journal articles originally published in print, otherwise known as digital journal backfiles, benefit library patrons by providing near instantaneous access to important older information and full-text searchability. Digital backfiles can serve as a reliable surrogate for their corresponding print journals which could be removed from the library, freeing up space for other patron services. Both benefits are realized when the scanned articles are of sufficient clarity to replace the print versions. Several studies have analyzed small and subject-narrow sections of Elsevier's digital backfile. This article contains a scan-quality analysis from 1578 journals that contain nearly four million articles and represents a significant portion of Elsevier's entire digital journal backfile. We divided journals into three categories and five discipline-specific classifications and compared them by logistic regression for differences in scan quality. Approximately 4.2 % of the articles analyzed contained illegible text, tables, or figures. This data may inform a library's acquisition, retention and space-planning decisions that in turn will affect a patron's access to and use of electronic journal articles. 相似文献

Nearly every major publisher offers open access content of some sort, but open access metadata standards are non‐existent amongst content providers. Users, librarians, content providers, and technology vendors who offer OpenURL resolvers and discovery services all stand to benefit from standardized ways to indicate what content is open access and what is not. Additionally, all stakeholders would benefit from a standardized method by which one can ascertain what form of open access any content may be; indeed, there are many definitions of open access. There is ample evidence that every publisher handles their content metadata differently and this creates inefficiencies in the scholarly information supply chain and leads to user confusion. Many initiatives are currently working on solutions to these problems including the NISO KBART workgroup, NISO's Open Discovery Initiative, and NISO's very recently created Open Access Initiative. There are also pre‐existing concepts based on services, such as CrossRef's CrossMark service and discovery systems that hold promise with respect to open access content and metadata. 相似文献
