Metadata harvesting for digital library integration in Ukraine: a comparative study of the OAI-PMH protocol and VuFind’s efficacy

Purpose This paper aims to the problem of building an environment to support scientific research in connection with the development of Open Science in Ukraine. Design/methodology/approach An overview of modern portals for aggregating scientific data was conducted. Analysis of available tools and identifying problems that arise when collecting data from digital libraries and journals was conducted. The validity of choosing VuFind as a tool that allows building an extraction–transformation–loading (ETL) approach for data aggregation and bringing the format and values of metadata fields to one view was experimentally verified. Findings During the experimental verification, problems related to the fact that the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) protocol does not have strict requirements for the data structure, which lead to the complexity of integration, despite the fact that this protocol occupied a leading position, were noted. To simplify these problems, an ETL approach that allowed for the use of ontological methods (e.g. data mapping, linked data and dictionaries to improve the semantics of data for integration processes) was considered. A review of the possibilities of modern tools for OAI-PMH integration, which were actively supported and developed, was conducted. Originality/value This paper was an attempt to outline the problems that arose in integrating resources, with the aim of developing future integration protocols that would have simple means of semantic data validation and built-in ETL mechanism.

Global status of dataset repositories at a glance: study based on OpenDOAR

PurposeThe study aims to shed light on the current state of “Dataset repositories” indexed in Directory of Open Access Repositories (OpenDOAR).Design/methodology/approachFrom each repository/record information, the Open-Access Policies, Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), year of creation and the number of data sets archived in the repositories were manually searched, documented and analyzed.FindingsDeveloped countries like the United Kingdom and the USA are primarily involved in the development of institutional open-access repositories comprising significant components of OpenDOAR. The most extensively used software is DSpace. Most data set archives are OAI-PMH compliant but do not follow open-access rules. The study also highlights the sites’ embrace of Web 2.0 capabilities and discovers really simple syndication feeds and Atom integration. The use of social media has made its presence known. Furthermore, the study concludes that the number of data sets kept in repositories is insufficient, although the expansion of such repositories has been consistent over the years.Practical implicationsThe work has the potential to benefit both researchers in general and policymakers in particular. Scholars interested in research data, data sharing and data reuse can learn about the present state of repositories that preserve data sets in OpenDOAR. At the same time, policymakers can develop recommendations and policies to assist in the construction and maintenance of repositories for data sets.Originality/valueAccording to the literature, there have been numerous studies on open-access repositories and OpenDOAR internationally, but no research has focused on repositories preserving content-type data sets. As a result, the study attempts to uncover various characteristics of OpenDOAR Data set repositories.

Peculiarities of Europeana Metadata as a Set of Information for Describing Digital Cultural Heritage

The relevance of the research. European integration is the main and unchanging foreign policy priority of Ukraine. Further development and deepening of relations between Ukraine and the EU are the main direction of its development. A new stage in the development of EU-Ukraine treaty relations, which began with Ukraine’s accession to the EU candidate status in June 2022, requires further raising awareness of Ukraine’s European integration among all members of society. Libraries can contribute to the formation of objective motivations among the population by understanding the practical benefits of cooperation with the EU. One of the ways of such integration for Ukrainian libraries is to become part of the European library network.
 The purpose of research is to identify the features of Europeana metadata for further digitization of library collections in Ukraine in order to preserve cultural heritage.
 The methodology. To achieve this goal, theoretical and general scientific research methods, such as analysis, synthesis, induction, and deduction, were used. The data visualization method and the method of generalization were used to present the Europeana data models.
 The results. The article defines the types of the Europeana operational model, provides a general overview of the classes defined in the Europeana data model and the process of interaction between Europeana data and wikidata.
 The scientific topicality. The article summarizes previous, primarily foreign, research on the peculiarities of the development of the Europeana funds. The article presents the data models of the Europeana that function to fill the web portal.
 The practical significance. The results of the research are presented in the form of Europeana data models and the definition of Europeana metadata types (descriptive, structural, administrative, markup language).
 The conclusion. The current operating model of Europeana uses the Open Archives Initiative’s Metadata Collection Protocol (OAI-PMH) and the Europeana Data Model (EDM) to import data through Metis, Europeana’s data collection and aggregation service. However, OAI-PMH is an outdated technology that is not web-oriented, resulting in high maintenance costs, especially for smaller institutions. Metadata can be divided into several categories, or types, for different data management purposes. Traditional library cataloging focuses, for example, on the identification and description of resources, but there are obviously other types of metadata that carry valuable information (structural, administrative, markup language).

The Implementation of Semantic Annotation Recognizing Technique in the Scraper Engine on the E-Publishing Website of the National Research and Innovation Agency (BRIN) Indonesia

The increasing need for swift information dissemination in line with modern technological advancements has emphasized the importance and significant impact of data analysis and processing as relevant academic disciplines. These processes encompass data acquisition from various sources, either through direct collection or extraction methods. Among the most crucial and widely utilized techniques for extracting data from the internet is web scraping, particularly when gathering data for research maintenance during the consolidation of multiple institutions into BRIN (National Research and Innovation Agency). Challenges emerge in effectively integrating existing research into a unified system without proper upkeep, as neglecting maintenance can lead to system degradation and hinder access to stored research. Successful maintenance necessitates centralized repositories for researchers' work data. The implementation of semantic annotation recognizing techniques within the web scraping feature of the E-Publishing website holds the potential to expedite this process. The use of web scraping promises to significantly simplify research data collection, while semantic annotation recognizing techniques are poised to streamline implementation, particularly due to the XML data foundation within the Open Archives Initiative (OAI) system. In the context of institution merging and research sustainability, technologies like web scraping and semantic annotation recognizing play pivotal roles in addressing these challenges.

A comparative study of India and Australia open access repositories in open DOAR

An open access repository or open archive is a digital platform that holds research output and provides free, immediate and permanent access to research results for anyone to use, download and distribute. To facilitate open access such repositories must be interoperable according to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Search engines harvest the content of open access repositories, constructing a database of worldwide, free of charge available research. OpenDOAR is the quality-assured, global Directory of Open Access Repositories. Its repositories provide free, open access to academic outputs and resources. This paper deals with Comparative analysis of India and Australia repositories listed in OpenDOAR in terms of their growth, type, operational status, content type, software, subject coverage, language and policies regarding content, submission, and preservation. Keywords: Digital Repositories, Institutional Repositories, Open Access, OpenDOAR.

Developed DICOM standard schema with DSpace

PurposeThis paper aims to present a novel DSpace-based medical image repository system planned explicitly for storing and retrieving clinical images using digital imaging and communication in medicine (DICOM) metadata standards. DSpace institutional repository software is widely used in an academic environment for accessing and mainly storing text-related files. DICOM images are particular types of images embedded with much system-generated metadata and organised using DICOM metadata standards.Design/methodology/approachThe present paper talks about institutional repository software (DSpace) in archiving DICOM images. In the current study, the authors have tried to integrate the DICOM metadata standard with DSpace, which was compatible with Dublin Core (DC) and open archives initiative – protocol for metadata harvesting (OAI-PMH). After combining the DICOM standard with DSpace and the repository tested with a sample of 5,000 images, the retrieval results using various DICOM tags was very satisfactory. This study paves for the use of open source software (OSS) in storing and retrieving medical images.FindingsThe author has provided the DSpace software to recognised DICOM (.dcm) files in the first stage. In the second stage, a patch was developed to identify the DICOM metadata standard in Dspace, which has inbuilt DC metadata standards. Finally, in the third stage, retrieval efficiency was tested with a 5,000 .dcm image using the DICOM tag and the results were very fruitful.Research limitations/implicationsA major limitation of this study was the size of the data (5,000 DICOM images) with which the authors have tested the system. The system scalability has to be tested on various fronts like on cloud and local servers with different configurations, for which a separate study has to be done.Practical implicationsOnce this system is in place, DICOM users can stock, retrieve and access the image from the Web platform. Furthermore, this proposed repository will be the warehouse of various DICOM images with reasonable storage costs.Originality/valueIn addition to exploring the opportunities of free open source software (FOSS) implementation in medical science, this study includes issues related to the performance of an open-source repository for retrieving and preserving medical images. It created and developed Open Source DICOM Medical Image Library with DICOM metadata standard with the help of DSpace. Thus, the study will generate value for library professionals and medical professionals and FOSS vendors to understand the medical market in the context of FOSS.

Index development with the keyword in context method in the online library catalog

Academic libraries have an essential role in the academic community. As a reference center, libraries provide access to online reference sources or book collections. One of the facilities provided is the library automation which facilitate users to access library resources. With an online catalog that is easy to operate, it will be easier for users to get information. However, libraries generally only provide interface search facilities which make it difficult for users to find information. This study aims to produce an index on the online library catalog using the KWIC (KeyWord in Context) method. The data was collected from the Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) on the Library server. In the data harvesting process, around 50,000 data were found to be processed. The finding in this study indicates that the library’s online catalog metadata index makes it easier for users to retrieve information.

DATA CURATION DAN RESEARCH DATA MANAGEMENT UNTUK TERWUJUDNYA INTEGRASI DATA RISET DI INDONESIA

Indonesia is actively supporting the research process that is conducted in their research institutions, by providing research funds for them. Many research institutions in Indonesia work in the similar field and their funding could also come from the same source. Based on that reason, there is a need to evaluate the data curation and research data management processes at Indonesian research institutions. The purposes of this research are to evaluate the existing research data conditions at several research institutions, issues associated with research data management, standards and tools to support the implementation of research data management, also finding a way to achieve research data integration for research institutions in Indonesia. Interviews were used as the method to gain data from several research institutions in Indonesia then it was analysed with the qualitative data analysis. Ultimately, the result shows that data access problem, data collection and awareness of researcher are the main complexities of the research data management process. While policies and regulations on research data management are considered important by research institutions to guide them along the process. The result also shows that integration between research institutions could be achieved by using supporting tools and protocols such as OAI-PMH (The Open Archives Initiative Protocol for Metadata Harvesting) and API (Application Programming Interface), integrated system and standard data format.

Using the Harvesting Method to Submit ETDs into ProQuest

The following case study describes an academic library’s recent experience implementing the harvesting method to submit electronic theses and dissertations (ETDs) into the ProQuest Dissertations & Theses Global database (PQDT). In this lesser-known approach, ETDs are deposited first in the institutional repository (IR), where they get processed, to be later harvested for free by ProQuest through the IR’s Open Archives Initiative (OAI) feed. The method provides a series of advantages over some of the alternative methods, including students’ choice to opt-in or out from ProQuest, better control over the embargo restrictions, and more customization power without having to rely on overly complicated workflows. Institutions interested in adopting a simple, automated, post-IR method to submit ETDs into ProQuest, while keeping the local workflow, should benefit from this method.

Data Science Tools for Monitoring the Global Repository Eco-System and its Lines of Evolution

The global network of scholarly repositories for the publication and dissemination of scientific publications and related materials can already look back on a history of more than twenty years. During this period, there have been many developments in terms of technical optimization and the increase of content. It is crucial to observe and analyze this evolution in order to draw conclusions for the further development of repositories. The basis for such an analysis is data. The Open Archives Initiative (OAI) service provider Bielefeld Academic Search Engine (BASE) started indexing repositories in 2004 and has collected metadata also on repositories. This paper presents the main features of a planned repository monitoring system. Data have been collected since 2004 and includes basic repository metadata as well as publication metadata of a repository. This information allows an in-depth analysis of many indicators in different logical combinations. This paper outlines the systems approach and the integration of data science techniques. It describes the intended monitoring system and shows the first results.

Development of Web Services: A Practical Approach for Libraries

Integrated library system is a part of institutional digital repository in modern library environment. Some popular open source software has been used in this regard. Development of an integrated institutional digital repository system is possible on the basis of global recommendations and local requirements of all libraries. OAI-PMH in Koha can be displayed in two ways such as sets and metadata with multilingual documents. The benefits of this study is harvest the records from the other library and it can make the union catalogue for anybody can be accessed from this integrated OAI-PMH harvesting framework available in Koha OPAC. This is the web 2.0 concept to achieve the multiple tasks of different library resources such as books, journals, magazines, reference books etc. for the better management and retrieval of resources among the library users. Digital resources are increasing in this modern age due to exponential growth of technological impact and its peripherals. IDRs will additionally include digital materials that subsist outside the physical and administrative bounds of any one digital library. IDRs will include all the processes and accommodations that are the backbone and nervous system of libraries. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a very high performance mechanism for client server architecture in repository interoperability. Broadly it can be classified in two ways such as data provider and service provider. Data Provider can access the structured standards global metadata by using OAI-PMH tool. Development of web services through Koha can be achieved in four ways such as OAI-PMH, ILS-DI, Z39.50, and OPAC tag cloud. On the other hand service providers then easily harvest the metadata through a set of six verbs of OAI-PMH based URL. Requests for data can be based on a timestamp range, and can be restricted to named sets defined by the provider. Data providers can only manage the XML based Dublin Core metadata format. It is possible to design and develop an integrated institutional digital repository in different ways. In this research paper highlights and displays the important interface such as OAI-PMH, ILS-DI, Z39.50, and tag cloud and all the interfaces have been displayed in Koha OPAC. The whole tasks have been developed and performed in Ubuntu operating system for easy installation, configuration, and retrieving of library resources among the users.

Journal Programs and Cross-Disciplinary Research

In order for innovative cross-disciplinary research to find its audience, it must be easily discovered by scholars, professional practitioners, and the public. Journal publishing programs in libraries operate under the principle that investment in open access publishing of quality peer-reviewed research is the best way to make that research visible to a global audience and to shift control of publishing from commercial entities to the academy. Library publishers are therefore not constrained, as commercial publishers are, by the need to publish only research that will ensure a profit. This means that library publishing programs can provide a home for cross-disciplinary journals that break new ground and that may take time to find an audience.
 The lack of a profit imperative for library publishing programs also means that the platform for hosting journals is provided to journals at little or no cost, which makes library publishing very attractive to editors looking for a place to publish a new journal. Once the infrastructure is operational, the cost to add a new journal to the system is negligible because the costs of maintaining the technology are already covered. This lowers the financial barriers to starting new journals, allowing editors to focus on the task of finding and publishing excellent peer-reviewed research instead of fundraising.
 Journal platforms used by library publishers are designed so that journals published on those systems automatically follow best practices and standards, such as those outlined by the Open Archives Initiative Protocol for Metadata Harvesting (OAI-MPH) that make the content readily discoverable by internet search engines. These platforms also integrate the use of machine-readable licenses that clearly indicate how the content can be used. In addition to infrastructure that ensures visibility, library publishing programs benefit from existing library expertise in collaboration, technology, copyright, data management, scholarly publishing, information literacy, digital preservation, and the effective promotion of online research.

NaturalHeritage: Bridging Belgian natural history collections

The Royal Belgian Institute of Natural Sciences (RBINS), the Royal Museum for Central Africa (RMCA) and Meise Botanic Garden house more than 50 million specimens covering all fields of natural history. While many different research topics have their own specificities, throughout the years it became apparent that with regards to collection data management, data publication and exchange via community standards, collection holding institutions face similar challenges (James et al. 2018, Rocha et al. 2014). In the past, these have been tackled in different ways by Belgian natural history institutions. In addition to local and national collaborations, there is a great need for a joint structure to share data between scientific institutions in Europe and beyond. It is the aim of large networks and infrastructures such as the Global Biodiversity Information Facility (GBIF), the Biodiversity Information Standards (TDWG), the Distributed System of Scientific collections (DiSSCo) and the Consortium of European Taxonomic Facilities (CETAF) to further implement and improve these efforts, thereby gaining ever increasing efficiencies. In this context, the three institutions mentioned above, submitted the NaturalHeritage project (http://www.belspo.be/belspo/brain-be/themes_3_HebrHistoScien_en.stm) granted in 2017 by the Belgian Science Policy Service, which runs from 2017 to 2020. The project provides links among databases and services. The unique qualities of each database are maintained, while the information can be concentrated and exposed in a structured way via one access point. This approach aims also to link data that are unconnected at present (e.g. relationship between soil/substrate, vegetation and associated fauna) and to improve the cross-validation of data. (1) The NaturalHeritage prototype (http://www.naturalheritage.be) is a shared research portal with an open access infrastructure, which is still in the development phase. Its backbone is an ElasticSearch catalogue, with Kibana, and a Python aggregator gathering several types of (re)sources: relational databases, REpresentational State Transfer (REST) services of objects databases and bibliographical data, collections metadata and the GBIF Internet Publishing Toolkit (IPT) for observational and taxonomical data. Semi-structured data in English are semantically analysed and linked to a rich autocomplete mechanism. Keywords and identifiers are indexed and grouped in four categories (“what”, “who”, “where”, “when”). The portal can act also as an Open Archives Initiatives Protocol for Metadata Harvesting (OAI-PMH) service and ease indexing of the original webpage on the internet with microdata enrichment. (2) The collection data management system of DaRWIN (Data Research Warehouse Information Network) of RBINS and RMCA has been improved as well. External (meta)data requirements, i.e. foremost publication into or according to the practices and standards of GBIF and OBIS (Ocean Biogeographic Information System: https://obis.org) for biodiversity data, and INSPIRE (https://inspire.ec.europa.eu) for geological data, have been identified and evaluated. New and extended data structures have been created to be compliant with these standards, as well as the necessary procedures developed to expose the data. Quality control tools for taxonomic and geographic names have been developed. Geographic names can be hard to confirm as their lack of context often requires human validation. To address this a similarity measure is used to help map the result. Species, locations, sampling devices and other properties have been mapped to the World Register of Marine Species and DarwinCore (http://www.marinespecies.org), Marine Regions and GeoNames, the AGRO Agronomy and Vertebrate trait ontologies and the British Oceanographic Data Centre (BODC) vocabularies (http://www.obofoundry.org/ontology/agro.html). Extensive mapping is necessary to make use of the ExtendedMeasurementOrFact Extension of DarwinCore (https://tools.gbif.org/dwca-validator/extensions.do).

Towards Identifying Author Confidence in Biomedical Articles

In an era where the volume of medical literature is increasing daily, researchers in the biomedical and clinical areas have joined efforts with language engineers to analyze the large amount of biomedical and molecular biology literature (such as PubMed), patient data, or health records. With such a huge amount of reports, evaluating their impact has long stopped being a trivial task. In this context, this paper intended to introduce a non-scientific factor that represents an important element in gaining acceptance of claims. We postulated that the confidence that an author has in expressing their work plays an important role in shaping the first impression that influences the reader’s perception of the paper. The results discussed in this paper were based on a series of experiments that were ran using data from the open archives initiative (OAI) corpus, which provides interoperability standards to facilitate effective dissemination of the content. This method may be useful to the direct beneficiaries (i.e., authors, who are engaged in medical or academic research), but also, to the researchers in the fields of biomedical text mining (BioNLP) and NLP, etc.

The Observation of Bahasa Indonesia Official Computer Terms Implementation in Scientific Publication

The government of the Republic of Indonesia had issued a regulation to substitute computer terms in foreign language that have been used earlier into official computer terms in Bahasa Indonesia. This regulation was stipulated in Presidential Decree No. 2 of 2001 concerning the introduction of official computer terms in Bahasa Indonesia (known as Senarai Padanan Istilah/SPI). After sixteen years, people of Indonesia, particularly for academics, should have implemented the official computer terms in their official publications. This observation is conducted to discover the implementation of official computer terms usage in scientific publications which are written in Bahasa Indonesia. The data source used in this observation are the publications by the academics, particularly in computer science field. The method used in the observation is divided into four stages. The first stage is metadata harvesting by using Open Archive Initiative - Protocol for Metadata Harvesting (OAI-PMH). Second, converting the harvested document (in pdf format) to plain text. The third stage is text-preprocessing as the preparation of string matching. Then the final stage is searching the official computer terms based on 629 SPI terms by using Boyer-Moore algorithm. We observed that there are 240,781 foreign computer terms in 1,156 scientific publications from six universities. This result shows that the foreign computer terms are still widely used by the academics.

Science Metadata Management, Interoperability and Data Citations of the National Institute of Polar Research, Japan

The Polar Data Centre (PDC) of the National Institute of Polar Research (NIPR) has a responsibility to manage polar science data as part of the National Antarctic Data Centre and the Science Committee on Antarctic Research. During the International Polar Year (IPY 2007–2008), a remarkable number of data/metadata involving multi-disciplinary science activities were compiled. Although the long-term stewardship of the accumulation of metadata falls to the data center of NIPR, the work has been in collaboration with the Global Change Master Directory, the Polar Information Commons, the World Data System and other data science bodies/communities under the International Council for Science. In addition, links with other data centers, such as the Data Integration and Analysis System Program of the Global Earth Observation System of Systems and the Polar Data Catalogue of Canada were initiated in 2014 using the Open Archives Initiative Protocol for Metadata Harvesting. The metadata compiled by the PDC were recently modified using an automatic attributing system and DataCite through the Japan Link Center.
