"Supporting FAIR Data Principles with Fedora"

David Wilcox has published "Supporting FAIR Data Principles with Fedora" in LIBER Quarterly.

Here's an excerpt:

Making data findable, accessible, interoperable, and re-usable is an important but challenging goal. From an infrastructure perspective, repository technologies play a key role in supporting FAIR data principles. Fedora is a flexible, extensible, open source repository platform for managing, preserving, and providing access to digital content. Fedora is used in a wide variety of institutions including libraries, museums, archives, and government organizations. Fedora provides native linked data capabilities and a modular architecture based on well-documented APIs and ease of integration with existing applications. As both a project and a community, Fedora has been increasingly focused on research data management, making it well-suited to supporting FAIR data principles as a repository platform. Fedora provides strong support for persistent identifiers, both by minting HTTP URIs for each resource and by allowing any number of additional identifiers to be associated with resources as RDF properties. Fedora also supports rich metadata in any schema that can be indexed and disseminated using a variety of protocols and services. As a linked data server, Fedora allows resources to be semantically linked both within the repository and on the broader web. Along with these and other features supporting research data management, the Fedora community has been actively participating in related initiatives, most notably the Research Data Alliance. Fedora representatives participate in a number of interest and working groups focused on requirements and interoperability for research data repository platforms. This participation allows the Fedora project to both influence and be influenced by an international group of Research Data Alliance stakeholders. This paper will describe how Fedora supports FAIR data principles, both in terms of relevant features and community participation in related initiatives.

"Facilitating and Improving Environmental Research Data Repository Interoperability"

Corinna Gries et al. have published "Facilitating and Improving Environmental Research Data Repository Interoperability" in Data Science Journal.

Here's an excerpt:

Environmental research data repositories provide much needed services for data preservation and data dissemination to diverse communities with domain specific or programmatic data needs and standards. Due to independent development these repositories serve their communities well, but were developed with different technologies, data models and using different ontologies. Hence, the effectiveness and efficiency of these services can be vastly improved if repositories work together adhering to a shared community platform that focuses on the implementation of agreed upon standards and best practices for curation and dissemination of data. Such a community platform drives forward the convergence of technologies and practices that will advance cross-domain interoperability. It will also facilitate contributions from investigators through standardized and streamlined workflows and provide increased visibility for the role of data managers and the curation services provided by data repositories, beyond preservation infrastructure. Ten specific suggestions for such standardizations are outlined without any suggestions for priority or technical implementation. Although the recommendations are for repositories to implement, they have been chosen specifically with the data provider/data curator and synthesis scientist in mind.

"Towards Open Access Self Archiving Policies: A Case Study of COAR"

Bijan Kumar Roy et al. have published "Towards Open Access Self Archiving Policies: A Case Study of COAR" in LIBER Quarterly.

Here's an excerpt:

This paper examines Open Access (OA) self archiving policies of different Open Access Repositories (OARs) affiliated to COAR (Confederation of Open Access Repositories) as partner institutes. The process of scrutiny includes three major activities—selection of databases to consult; comparison and evaluation of Open Access policies of repositories listed in the selected databases and attached to COAR group; and critical examination of available self archiving policies of these OA repositories against a set of selected criteria. The above steps lead to reporting the following results: key findings have been identified and highlighted; common practices have been analyzed in relation to the focus of this paper; and a best practice benchmark has been suggested for popularizing and strengthening OARs as national research systems. This paper may help administrators, funding agencies, policy makers and professional librarians in devising institute-specific self archiving policies for their own organizations.

Search Results Ranking Using Machine-Learning Algorithms: "Best Match: New Relevance Search for PubMed"

Nicolas Fiorini et al. have published "Best Match: New Relevance Search for PubMed" in PLOS Biology.

Here's an excerpt:

PubMed is a free search engine for biomedical literature accessed by millions of users from around the world each day. With the rapid growth of biomedical literature—about two articles are added every minute on average—finding and retrieving the most relevant papers for a given query is increasingly challenging. We present Best Match, a new relevance search algorithm for PubMed that leverages the intelligence of our users and cutting-edge machine-learning technology as an alternative to the traditional date sort order. The Best Match algorithm is trained with past user searches with dozens of relevance-ranking signals (factors), the most important being the past usage of an article, publication date, relevance score, and type of article. This new algorithm demonstrates state-of-the-art retrieval performance in benchmarking experiments as well as an improved user experience in real-world testing (over 20% increase in user click-through rate). Since its deployment in June 2017, we have observed a significant increase (60%) in PubMed searches with relevance sort order: it now assists millions of PubMed searches each week. In this work, we hope to increase the awareness and transparency of this new relevance sort option for PubMed users, enabling them to retrieve information more effectively.

"HydraDAM2: Extending Fedora 4 and Hydra for Media Preservation"

Jon W. Dunn et al. have self-archived "HydraDAM2: Extending Fedora 4 and Hydra for Media Preservation."

Here's an excerpt:

The overarching goal of the HydraDAM2 project, funded by a grant from the National Endowment for the Humanities Preservation and Access Research and Development program, was to extend the existing HydraDAM digital asset management system, developed with prior NEH support, to be able to serve as a digital preservation repository for time-based media collections implementable at a wide range of institutions using multiple digital storage strategies. The new open source digital preservation repository system developed as part of the project by partners Indiana University (IU) and WGBH, known as Phydo, is based on the Fedora 4.x digital repository system and Samvera (formerly Hydra) repository application development framework and is intended to support storage and long-term preservation management of audio and video files and their accompanying metadata. This white paper describes the work of the HydraDAM2 project to develop the Phydo system, along with future plans.

Cornell University Library Repository Principles and Strategies Handbook

Erin Faulder et al. have self-archived the "Cornell University Library Repository Principles and Strategies Handbook."

Here's an excerpt:

The handbook provides support for both new and existing repository managers, comprising both recommended practices and specifically identified action steps that will allow them to track their progress and identify gaps. Each section of the handbook covers a different strategic area of repository management, standing largely on its own and linking to other sections when appropriate. Although there is no primary section order, we recommend starting with Defining Repository Scope and Service Planning. The handbook specifically addresses principles and practices pertaining to digital repositories, where a digital repository can be defined as: a system, the purpose of which is to store, present, and preserve a collection of data for which the library provides services. That is, the term refers specifically to the application as opposed to the content (collections, objects and metadata) within.

"The Types, Frequencies, and Findability of Disciplinary Grey Literature within Prominent Subject Databases and Academic Institutional Repositories"

Wanda R. Marsolek et al. have published "The Types, Frequencies, and Findability of Disciplinary Grey Literature within Prominent Subject Databases and Academic Institutional Repositories" in the Journal of Librarianship and Scholarly Communication.

Here's an excerpt:

INTRODUCTION In many disciplines grey literature, or works that are more ephemeral in nature and are not typically published through traditional scholarly channels, are heavily used alongside traditional materials and sources. We were interested in the type and frequency of grey literature in subject databases and in North American institutional repositories (IRs) as well as what disciplines use grey literature. METHODS Over 100 subject databases utilized by academic researchers and the IRs of over 100 academic institutions were studied. Document type, search capabilities, and level of curation were noted. RESULTS Grey literature was present in the majority (68%) of the literature databases and almost all IRs (95%) contained grey literature. DISCUSSION Grey literature was present in the subject databases across all broad disciplines including arts and humanities. In these resources the most common types of grey literature were conference papers, technical reports, and theses and dissertations. The findability of the grey literature in IRs varied widely as did evidence of active collection development. CONCLUSION Recommendations include the development of consistent metadata standards for grey literature to enhance searching within individual resources as well as supporting future interoperability. An increased level of collection development of grey literature in institutional repositories would facilitate preservation and increase the findability and reach of grey literature.
