Abstract
Purpose
The purpose of this paper is to focus on the quality of the connections (linkset) among thesauri published as Linked Data on the Web. It extends the cross-walking measures with two new measures able to evaluate the enrichment brought by the information reached through the linkset (lexical enrichment, browsing space enrichment). It fosters the adoption of cross-walking linkset quality measures besides the well-known and deployed cardinality-based measures (linkset cardinality and linkset coverage).
Design/methodology/approach
The paper applies the linkset measures to the Linked Thesaurus fRamework for Environment (LusTRE). LusTRE is selected as testbed as it is encoded using a Simple Knowledge Organisation System (SKOS) published as Linked Data, and it explicitly exploits the cross-walking measures on its validated linksets.
Findings
The application on LusTRE offers an insight of the complementarities among the considered linkset measures. In particular, it shows that the cross-walking measures deepen the cardinality-based measures analysing quality facets that were not previously considered. The actual value of LusTRE’s linksets regarding the improvement of multilingualism and concept spaces is assessed.
Research limitations/implications
The paper considers skos:exactMatch linksets, which belong to a rather specific but a quite common kind of linkset. The cross-walking measures explicitly assume correctness and completeness of linksets. Third party approaches and tools can help to meet the above assumptions.
Originality/value
This paper fulfils an identified need to study the quality of linksets. Several approaches formalise and evaluate Linked Data quality focusing on data set quality but disregarding the other essential component: the connection among data.

Abstract
Purpose
The purpose of this paper is to present methods for customized mapping and metadata transfer from DSpace to Online Computer Library Center (OCLC), which aims to improve Electronic Theses and Dissertations (ETD) work flow at libraries using DSpace to store theses and dissertations by automating the process of generating MARC records from Dublin Core (DC) metadata in DSpace and exporting them to OCLC.
Design/methodology/approach
This paper discusses how the Shocker Open Access Repository (SOAR) at Wichita State University (WSU) Libraries and ScholarsArchive at Oregon State University (OSU) Libraries harvest theses data from the DSpace platform using the Metadata Harvester in MarcEdit developed by Terry Reese at OSU Libraries. It analyzes certain challenges in transformation of harvested data including handling of authorized data, dealing with data ambiguity and string processing. It addresses how these two institutions customize Library of Congress's XSLT (eXtensible Stylesheet Language Transformations) mapping to transfer DC metadata to MarcXML metadata and how they export MARC data to OCLC and Voyager.
Findings
The customized mapping and data transformation for ETD data can be standardized while also requiring a case‐by‐case analysis. By offering two institutions' experiences, it provides information on the benefits and limitations for those institutions that are interested in using MarcEdit and customized XSLT to transform their ETDs from DSpace to OCLC and Voyager.
Originality/value
The new method described in the paper can eliminate the need for double entry in DSpace and OCLC, meet local needs and significantly improve ETD work flow. It offers perspectives on repurposing and managing metadata in a standard and customizable way.

Abstract
Purpose
With the aim of developing a conceptual framework which aims to facilitate semantic metadata interoperability, this paper explores overarching conceptual issues on how traditional library information organisation schemes such as online public access catalogues (OPACs), taxonomies, thesauri, and ontologies on the one hand versus Web 2.0 technologies such as social tagging (folksonomies) can be harnessed to provide users with satisfying experiences.
Design/methodology/approach
This paper reviews works in relation to current metadata creation, utilisation and interoperability approaches, focusing on how a social constructivist philosophical perspective can be employed to underpin metadata decisions in digital libraries. Articles are retrieved from databases such as EBSCO host and Emerald and online magazines such as D‐Lib and Ariadne. Books, news articles and blog posts that are deemed relevant are also used to support the arguments put forward in this paper.
Findings
Current metadata approaches are deeply authoritative and metadata deployments in digital libraries tend to favour an objectivist approach with focus on metadata simplicity. It is argued that unless information objects are enriched with metadata generated through a collaborative and user‐driven approach, achieving semantic metadata interoperability in digital libraries will remain difficult.
Practical implications
In this paper, it is indicated that the number of metadata elements (fields) constituting a standard has a direct bearing on metadata richness, which in turn directly affects semantic interoperability. It is expected that this paper will contribute towards a better understanding of harnessing user‐driven metadata.
Originality/value
As suggested in this paper, a conceptual metadata framework underpinned by a social constructivist approach substantially contributes to semantic interoperability in digital libraries.

Abstract
Purpose
The purpose of this paper is to examine how archaeological document collections are layered entities and, thus, consist of documents that may be in discordance with one another. Implications of this scenario for scientific study are discussed. Tensions arise between archaeological and Information and Library Science practices. Curators become primary agents in reconstructing the appropriate representational continuity of these documents.
Design/methodology/approach
This paper is an in-depth examination of documentation in the Glenn Black Laboratory of Archaeology. It assesses how representations between documents are maintained as part of the collection management process. A document archaeological analysis of the Angel Mounds Collection shows how discordant data between documents is reconciled.
Findings
The study shows how documentary institutions are central to maintaining the chain of reference necessary to maintain the veracity of scientific data. Documents are embedded within a professional network of classification control that has implications for the conceptualization of documents. The study can help scholars gain a more nuanced view of the role of documents in scientific knowledge creation.
Social implications
Curatorial intervention plays a central role in maintaining the veracity of scientific data. In this way, the narrative shows how social and professional scientific discourses are impacted by curatorial intervention and that this process is inextricable from how we understand “knowledge” broadly construed.
Originality/value
This study examines how documents are embedded within a broader collection context and further studies should acknowledge this. It shows how documents within the domain of archaeology pose specific issues of concern for document curators and scholars, especially in relation to the documentation of spatial data, which is central to this work.

Abstract
Purpose
The purpose of the paper is to address the following question: What can novels reveal about what leadership nonfiction sources miss or obscure?
Design/methodology/approach
The paper reviews the benefits that are derived from the use of literature in the examination of leadership, compares and contrasts three novel experiments in the examination of literature and leadership, and examines the impact of one approach as reflected in student assignments and exit interviews.
Findings
Student reflection papers morphed from descriptive reviews to reflections expressed through poetry, artwork and personal experiences. Students also deepened their views on what leadership is and means. Exit interviews revealed student significant reflection on personal views in a number of areas. The longitudinal follow up of students expanded their flexibility and ability to listen and understand how and why people approach leadership in different ways. They also felt it increased their openness to new or different approaches and encouraged them to think more independently.
Practical implications
One implication of the approach of this class is how the authors embraced questions to guide the students and faculty. Instead of listing topics and assigning categorical meaning, the approach of the class was organized around questions, such as, “is leadership real or imagined? Am I ready to take responsibility?
Social implications
The power of storytelling is unmistakable. The value of storytelling is that it allows the reader to escape from the day-to-day challenges we face to find how others are facing challenges sometimes very similar to our own.
Originality/value
The article compares and contracts three experiments in the examination of literature and leadership. The paper then examines one approach to literature and leadership in terms of the impact on students (papers, exit interview and longitudinal follow-up). Findings are assessed with the works of Gardner, Bennis and Hartley stressing the possibilities of storytelling as a unique approach to studying and practicing leadership.

Abstract
In the fall of 2002, the University of Illinois Library at Urbana‐Champaign received a grant from the Institute of Museum and Library Services (IMLS) to implement a collection registry and item‐level metadata repository for digital collections and content created by or associated with projects funded under the IMLS National Leadership Grant (NLG) program. When built, the registry and metadata repository will facilitate retrieval of information about digital content related to past and present NLG projects. The process of creating these services also is allowing us to research and gain insight into the many issues associated with implementing such services and the magnitude of the potential benefit and utility of such services as a way to connect, bring together, and make more visible a broad range of heterogeneous digital content. This paper describes the genesis of the project, the rationale for architectural design decisions, challenges faced, and our progress to date.

Abstract
Purpose
The purpose of this paper is to examine the characteristics of managing records in a cloud computing environment and compare these with existing archiving models, exemplified by the open archival information system (OAIS) reference model.
Design/methodology/approach
The authors compare the functional entities in OAIS with a layered model of cloud computing, in which services are abstracted and shared between layers.
Findings
It is concluded that there are a number of areas where OAIS does not integrate well with cloud computing systems. Based on the findings, a new layered model for a cloud archiving system is defined using the concepts and information types from the OAIS reference model. The proposed model allows the sharing of functionality and information objects by making them available as services to higher layers. The model covers the entire document lifecycle, making archive functionality such as preservation planning possible at an early stage and helping to simplify records transfer.
Research limitations/implications
The model provides a simple, OAIS compatible approach to representing how digital objects and necessary metadata can be transferred from content creation systems to archives systems.
Originality/value
Whereas a lot of research has been done on the technical aspects of cloud storage, there is a lack of focus on how to comprehensively integrate records transfer and preservation in cloud systems. This paper fills in some of the gaps.

Abstract
Purpose
The purpose of this paper is to examine affordable access and digital preservation solutions for digital collections developed by under-resourced small- and mid-sized cultural heritage organizations.
Design/methodology/approach
The paper presents a case study of Jeffco Stories, a collection of digitized oral histories created by the Jefferson County Public Library in Colorado.
Findings
This paper describes how the Jefferson County Public Library undertook a migration project of its oral history digital collection into an open-access platform, Omeka, and selected DuraCloud as a hosted digital preservation service.
Research limitations/implications
As a case study, this paper is limited to one institution’s experience with selecting access and digital preservation solutions.
Practical/implications
This paper is relevant to librarians and archivists who are exploring access and preservation solutions for digital collections and to those who are considering migrating to open-access content management systems and cloud-based digital preservation solutions.
Originality/value
This paper presents a case of a public library and the challenges in finding affordable access and digital preservation solutions for small digital collections.

Abstract
This chapter provides “viewpoints” on the education of learners with extensive and pervasive support needs. That is, students who require the most support to learn, often categorized as having intellectual disability, multiple disabilities, autism spectrum disorder, or related disabilities. The lenses through which we provide these viewpoints are historical and future-oriented; we begin with historic perspectives on the education of students with extensive and pervasive support needs, and then provide 21st century viewpoints for these learners. We interpret the notion of viewpoints in two ways: first, consistent with a viewpoint as indicating an examination of objects (in this case, practices and interventions) from a distance so as to be able to compare and judge; and, second, viewpoint as indicating our perspective on said interventions and practice.
