Transitioning from the ecological fieldwork to an online repository: a digital library solution and evaluation

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.

PurposeTo make CDS/ISIS databases OAI‐compliant.Design/methodology/approachOne of the biggest obstacles for information dissemination to a user community is that many digital libraries or bibliographic databases use heterogeneous technologies that inhibit interoperability. The Open Archives Initiative (OAI) addresses interoperability by using a framework to facilitate the discovery of content stored in distributed archives or bibliographic databases through the use of the OAI Protocol for Metadata Harvesting (OAI‐PMH). Though the OAI‐PMH is becoming the de facto standard, many of the legacy databases or bibliographic systems, for various reasons, are not OAI‐compliant. CDS/ISIS is one such database system. In this paper, we discuss the static repository (SR) approach to make CDS/ISIS databases OAI‐compliant. The records from a CDS/ISIS database are exported onto a file and the exported records are then converted to the SR XML file format. The SR file is made OAI‐compliant either by ingesting it into the Kepler Archivelet or through the intermediation of a static repository gateway (SRG).FindingsThe SR is a simple approach for making bibliographic records contained in non‐OAI‐compliant systems, OAI‐compliant.Research limitations/implicationsThe SR approach is meant for records, which are relatively static. If the OAI‐compliance is achieved through the SRG, then the number of records contained in a SR file should not exceed 5,000. However, if the SR file is ingested into the Kepler Archivelet, then there is no restriction on the number of records contained in a SR file.

Motivated by preservation and resource discovery, we examine how digital resources, and not just metadata about resources, can be harvested using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We review and critique existing techniques for identifying and gathering digital resources using metadata harvested through the OAI-PMH. We introduce an alternative solution that builds on the introduction of complex object formats that provide a more accurate way to describe digital resources. We argue that the use of complex object formats as OAI-PMH metadata formats results in a reliable and attractive approach for incremental harvesting of resources using the OAI-PMH.

Having indexed much of the "surface" Web, search engines are now using various approaches to index the "deep" Web. At the same time, institutional repositories and digital libraries are adopting the open archives initiative protocol for metadata harvesting (OAI-PMH) to expose their holdings. The authors harvested nearly 10 million records from OAI-PMH repositories. From these records, they extracted 3.3 million unique resource URLs and then conducted searches on samples from this collection to determine how much of the OAI-PMH corpus the three major search engines have indexed.

Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) provides an application-independent interoperability framework based on metadata harvesting. It is an effective way of sharing metadata between gateway services. The chapter gives an overview of Open Archives Initiative and underscores development, structure, and basic working of OAIPMH for harvesting procedures. It also traces the emerging trends in the use of Open Archive Initiative-Protocol for Metadata Harvesting (OAI-PMH) by open access repositories to support interoperability among globally distributed information systems. The study was carried out by consulting the database of Directory of Open Access Repositories (OpenDOAR), which is an authoritative directory of academic open access repositories. The study observed growth in the use and application of OAI-PMH protocol by OA repositories at a global level. Growth in the number of OAI-PMH complaint repositories provides an ample justification for its distinction among varied protocols to be utilized for resource sharing in knowledge society. However, developing and underdeveloped nations need to be made aware of the benefits of utilizing the harvesting capabilities of this protocol. The study provides an opportunity to understand the astounding growing trends in the use of the protocol in different setups.

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) was first released in January 2001. Since that time, the protocol has been adopted by a broad community and become the focus of a number of research and implementation projects. We describe the various activities building on the OAI-PMH since its first release. We then describe the activities and decisions leading up to the release of a stable Version 2 of the OAI-PMH. Finally, we describe the key features of OAI-PMH Version 2.KeywordsDigital LibraryData ProviderSimple Object Access ProtocolRegistration ServiceMellon FoundationThese keywords were added by machine and not by the authors.

In this paper we study the problem of representing, managing and exchanging hierarchically structured data in the context of a Digital Library (DL). We present the NEsted SeTs for Object hieRarchies (NESTOR) framework defining two set data models that we call: the Set Model (NS-M) and the Inverse Nested Set Model (INSM) based on the organization of nested sets which enable the representation of hierarchical data structures. We present the mapping between the tree data structure to NS-M and to INS-M. Furthermore, we shall show how these set data models can be used in conjunction with Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) adding new functionalities to the protocol without any change to its basic functioning. At the end we shall present how the couple OAI-PMH and the set data models can be used to represent and exchange archival metadata in a distributed environment.

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.

We present here the research work on data mining technologies for complicated attributes relationship in digital library collections. Firstly our work and ideology is introduced as the research ba ckground of this paper. Digital library evaluation is an important topic in information systems domain. We creatively import data mining technologies into it to get an intelligent decision support. But traditional data prediction algorithm didn't work well. This is the problem which would be solved in this paper. Secondly related preliminary research is introduced. We researched on attributes of digital library collections, proposed a parallel discretization algorithm based on z-score theory, and by the discretization algorithm disc overed a complicated condition attribute relation among attributes, it is the reason why traditional data prediction algorithm didn't wor k well. At last a stratified decision tree algorithm for value prediction about digital collection is put forward as the ultimate solution to solve the problem. Stratified attribute concept is imported in this algorithm. It can expand the selection of splitting attribute in decis ion tree from flat information to stereoscopic information, eliminate the influence of complicated condition attribute relationsh ip, nested use existing decision tree algorithms, and solve the bottleneck of data mining application in digital library evaluation.

Users’ evaluation of digital libraries (DLs): Their uses, their criteria, and their assessment

Purpose This study aims to understand the technical and operational challenges encountered by multilingual digital libraries and their strategies to solve problems in sustaining multilinguality services for digital libraries. Design/methodology/approach Using the multiple-case method, this study investigated two digital libraries that have sustained multilinguality for over a decade: the World Digital Library and the Digital Library of the Caribbean. Findings This study identified eight factors that contributed to the success of the two multilingual digital libraries and eight technical and operational challenges they have faced. A framework for digital libraries to sustain multilinguality is proposed. This framework illustrates the challenges and strategies to address the challenges in 11 aspects: creation, leadership, collaboration, content, metadata, translation, funding, technology, preservation, staffing and copyright. Research limitations/implications This study focused on two multilingual digital libraries administered in the USA, though they do not fully represent multilingual digital libraries in the USA. Therefore, the findings from the study may not apply to multilingual digital libraries the USA or other countries. As on-site interviews of both digital libraries were conducted at the beginning of 2019, the timeframe of this study is up to that date. Practical implications With more users worldwide seeking information online, more digital libraries will be providing multilingual services. This study provides guidelines to digital library developers and archivists for building and sustaining their digital libraries or archives. The experience and lessons learned from these two digital libraries may also help to better understand challenges and use effective strategies in building and sustaining multilinguality. Social implications The users and communities of digital libraries will be able to learn the benefits and challenges as related to building and sustaining digital library services. These services always need support to better serve their users and communities. Originality/value As the first multiple-case research that investigates in-depth challenges and approaches of digital libraries in sustaining multilinguality, this study presents a general picture of how the two digital libraries have succeeded in sustaining multilinguality. Theoretically, the study enriches the literature by providing a more comprehensive sustainability framework for multilinguality. This framework specifies possible aspects to consider for gaining sustainability of multilingual digital libraries and offers useful guidelines and insights for the digital library community to build multilingual services.

Major factors related to the economic, social and environmental sustainability of digital libraries have been discussed. Some research in digital information systems and services in general, and digital libraries in particular, have been discussed to illustrate different issues of sustainability. Based on these discussions the paper, for the first time, proposes a conceptual model and a theoretical research framework for sustainable digital libraries. It shows that the sustainable business models to support digital libraries should also support equitable access supported by specific design and usability guidelines that facilitate easier, better and cheaper access, support the personal, institutional and social culture of users, and at the same time conform with the policy and regulatory frameworks of the respective regions, countries and institutions.

This paper presents a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital library evaluation in the Libyan context. The study is framed in the evaluation of a bilingual digital library: The National Oil Corporation (NOC) – Digital Library in Libya. It is worth mentioning in this context that this study is the first of its kind to address evaluation issues in the context of Arabic language and it is limited to evaluate the effectiveness of the design of the prototype digital library which was designed using Greenstone digital library software. This paper discusses the evaluation of the prototype and reviews the analysis of the questionnaire, which was used for gathering data pertaining to the digital library that was built. The paper intends to discuss the methodology used for evaluating the prototype digital library, the framework, and the steps implemented to reach the final goal. Users’ opinions and views on the digital library are also presented in this paper. Evaluating the prototype digital library is considered an important stage towards developing a full-scale NOC digital library

We present Opal, a light-weight framework for interactively locating missing web pages (http status code 404). Opal is an example of in vivo preservation: harnessing the collective behavior of web archives, commercial search engines, and research projects for the purpose of preservation. Opal servers learn from their experiences and are able to share their knowledge with other Opal servers by mutual harvesting using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Using cached copies that can be found on the web, Opal creates lexical signatures which are then used to search for similar versions of the web page. We present the architecture of the Opal framework, discuss a reference implementation of the framework, and present a quantitative analysis of the framework that indicates that Opal could be effectively deployed.
