Abstract

Purpose

The purpose of this paper is to propose a Resource Description Framework (RDF)-based approach to transform metadata crosswalking from equivalent lexical element mapping into semantic mapping with various contextual relationships. RDF is used as a crosswalk model to represent the contextual relationships implicitly embedded between described objects and their elements, including semantic, hierarchical, granular, syntactic and multiple object relationships to achieve semantic metadata interoperability at the data element level.

Design/methodology/approach

This paper uses RDF to translate metadata elements and their relationships into semantic expressions, and also as a data model to define the syntax for element mapping. The feasibility of the proposed approach for semantic metadata crosswalking is examined based on two use cases – the Archives of Navy Ships Project and the Digital Artifacts Project of National Palace Museum in Taipei – both from the Taiwan e-Learning and Digital Archives Program.

Findings

As the model developed is based on RDF-based expressions, unsolved issues related to crosswalking, such as sets of shared terms, and contextual relationships embedded between described objects and their metadata elements could be manifested into a semantic representation. Corresponding element mapping and mapping rules can be specified without ambiguity to achieve semantic metadata interoperability.

Research limitations/implications

Five steps were developed to clarify the details of the RDF-based crosswalk. The RDF-based expressions can also serve as a basis from which to develop linked data and Semantic Web applications. More use cases including biodiversity artifacts of natural history museums and literary works of libraries, and conditions, constraints and cardinality of metadata data elements will be required to make revisions to fine tune the proposed RDF-based metadata crosswalk.

Originality/value

In addition to reviving contextual relationships embedded between described objects and their metadata elements, nine types of mapping rules were developed to achieve a semantic metadata crosswalk which will facilitate the design of related mapping software. Furthermore, the proposed approach complements existing crosswalking documents provided by authoritative organizations, and enriches mapping language developed by the CIDOC community.

Abstract

Purpose

Information from Current Research Information Systems (CRIS) is stored in different formats, in platforms that are not compatible, or even in independent networks. It would be helpful to have a well-defined methodology to allow for management data processing from a single site, so as to take advantage of the capacity to link disperse data found in different systems, platforms, sources and/or formats. Based on functionalities and materials of the VLIR project, the purpose of this paper is to present a model that provides for interoperability by means of semantic alignment techniques and metadata crosswalks, and facilitates the fusion of information stored in diverse sources.

Design/methodology/approach

After reviewing the state of the art regarding the diverse mechanisms for achieving semantic interoperability, the paper analyzes the following: the specific coverage of the data sets (type of data, thematic coverage and geographic coverage); the technical specifications needed to retrieve and analyze a distribution of the data set (format, protocol, etc.); the conditions of re-utilization (copyright and licenses); and the “dimensions” included in the data set as well as the semantics of these dimensions (the syntax and the taxonomies of reference). The semantic interoperability framework here presented implements semantic alignment and metadata crosswalk to convert information from three different systems (ABCD, Moodle and DSpace) to integrate all the databases in a single RDF file.

Findings

The paper also includes an evaluation based on the comparison – by means of calculations of recall and precision – of the proposed model and identical consultations made on Open Archives Initiative and SQL, in order to estimate its efficiency. The results have been satisfactory enough, due to the fact that the semantic interoperability facilitates the exact retrieval of information.

Originality/value

The proposed model enhances management of the syntactic and semantic interoperability of the CRIS system designed. In a real setting of use it achieves very positive results.

Abstract

Purpose

The purpose of this paper is to investigate what metadata elements for access points currently exist to represent diverse library reading materials, either in libraries or from external sources, as well as what metadata elements for access points are currently not present but are necessary to represent diverse library reading materials.

Design/methodology/approach

A field scan of thirteen contemporary metadata schemas identified elements that might serve as potential access points regarding the diversity status of resource creators as well as topical or thematic content. Elements were semantically mapped using a metadata crosswalk to understand the intellectual and conceptual space of the elements. Element definitions and application of controlled vocabularies were also examined where possible to offer an additional context.

Findings

Metadata elements describing gender, occupation, geographic region, audience and age currently exist in many schemas and could potentially be used to offer access to diverse library materials. However, metadata elements necessary to represent racial, ethnic, national and cultural identity are currently not present in specific forms necessary for enabling resource access and collection assessment. The lack of distinct elements contributes to the implicit erasure of marginalized identities.

Originality/value

The search for metadata describing diversity is a first step toward enabling more systematic access to diverse library materials. The need for systematic description of diversity to make visible and promote diverse materials is highlighted in this paper. Though the subject of this paper is library organization systems and, for clarity, uses terms specific to the library profession, the issues present are relevant to all information professionals and knowledge organization systems.

Abstract

Purpose

The purpose of this paper is to describe the Electronic Theses and Dissertations program implemented and managed by the Indiana State University since 2009. The paper illustrates issues relating to the background, policies, platform, workflow and cataloging, as well as the publication and preservation of graduate scholarship.

Design/methodology/approach

The authors examined many aspects of the Electronic Theses and Dissertations program and addressed issues dealt before, during and after the publication of the electronic theses and dissertations collection. The approaches the authors utilized are literature review and personal management experience from working on the program.

Findings

Implementing an Electronic Theses and Dissertations program involves providing a series of management services. These services include developing relevant policies, implementing an archiving and publication platform and creating submission and publishing workflows, as well as cataloging, disseminating and preserving the student collection. Openly publishing the collection through a range of access points significantly increases its visibility and accessibility. Adopting several archival and preservation strategies ensures the long-term readiness of the collection.

Originality/value

This paper will provide useful practices for implementing an ETD program to those institutions new to the ETD initiative process. It also contributes to the current body of literature and to the overall improvement of ETD programs globally.

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

This study aims to explore how metadata have been applied in GLAM (galleries, libraries, archives and museums) institutions in New Zealand (NZ) and to analyse its overall quality with the interoperability of the metadata element set especially in mind.

Design/methodology/approach

The first stage of data collection involved an analysis of the metadata records from 16 institutions from the NZ GLAM sector to examine the types and extent of metadata used. However, by looking at publicly accessible metadata records, it was impossible to determine the full extent of metadata created, especially when there could be metadata that were kept in‐house. This was complemented with interviewing of staff from the institutions concerned.

Findings

The study found that metadata records for digital images in four types of institutions have different emphases on metadata functions and a variety of metadata are not applied on a consistent basis. The lack of technical data in metadata records means that digital visual images are not always well protected. There is a consensus among those interviewed that metadata sharing is important. However, the wide use of a proprietary system which comes with pre‐existing metadata fields could result in a lack of flexibility and a risk that institutions adopt cataloguing practices to accommodating their collection management systems rather than to the requirements for interoperability and long‐term preservation.

Originality/value

In addition to studying metadata quality in GLAM digital image repositories, the study also examined the rationale and factors affecting the current practice via interviews with representatives from the institutions concerned. This shed light on potential barriers to interoperability that warranted further examination.

Abstract

Purpose

To research a resource description framework (RDF) based digital library system that facilitates digital resource management and supports knowledge management for an interoperable information environment.

Design/methodology/approach

The paper first introduces some of issues with metadata management and knowledge management and describes the needs for a true interoperable environment for information transferring across domains. A journal delivery application has been implemented as a concept‐proof project to demonstrate the usefulness of RDF in digital library systems.

Findings

The RDF‐based digital library system at the University of Arizona Libraries provides an easy way for digital resource management by integrating other applications regardless of metadata formats and web presence.

Practical implications

A journal delivery application has been running in the RDF‐based digital library system since April 2005. An electronic theses and dissertation application will be handled by the same system.

Originality/value

The paper suggests to use RDF, the semantic web technology, as a new approach to facilitate knowledge management and metadata management. Using RDF technology brings new ways to manage and discover information for libraries.
