"Linked Data Editors: Where Are We Now, Challenges and Considerations"


With the growing recognition of the advantages offered by linked data within the library community, libraries have made a lot of effort to support cataloging and metadata professionals in transitioning to linked data, which has led to the development of linked data editors. Although the available editors facilitate linked data-based input templates and output formats, these tools nonetheless have room for improvement. In this Communication on Practice, the authors compare two notable linked data editors based on their supported features and functions. They then delve into considerations when designing user-friendly and ontology-agnostic linked data editors. Finally, the authors address the challenges encountered by libraries during the transition to linked data production and examine the broader implications of this transition for information organization professionals.

"Using Linked Data for Discovery and Preservation"

Sayeed Choudhury has published "Using Linked Data for Discovery and Preservation" in EDUCAUSE Review.

Here's an excerpt:

Linked data has been discussed since the beginning of the World Wide Web 30 years ago (i.e., the so-called semantic web). For something potentially so important, this begs the question: Why hasn't linked data more directly affected galleries, libraries, archives, and museums (aka GLAM)?

"An Overview of the Current State of Linked and Open Data in Cataloging"

Irfan Ullah et al. have published "An Overview of the Current State of Linked and Open Data in Cataloging" in Information Technology and Libraries.

Here's an excerpt:

Although several reviews and survey articles on the application of Linked Data principles to cataloging have appeared in literature, a generic yet holistic review of the current state of Linked and Open Data in cataloging is missing. To fill the gap, the authors have collected recent literature (2014–18) on the current state of Linked Open Data in cataloging to identify research trends, challenges, and opportunities in this area and, in addition, to understand the potential of socially curated metadata in cataloging mainly in the realm of the Web of Data. . . . Some of the findings of the review are: Linked and Open Data is becoming the mainstream trend in library cataloging especially in the major libraries and research projects of the world; with the emergence of Linked Open Vocabularies (LOV), the bibliographic metadata is becoming more meaningful and reusable; and, finally, enriching bibliographic metadata with user-generated content is gaining momentum.

"Creating Structured Linked Data to Generate Scholarly Profiles: A Pilot Project using Wikidata and Scholia"

Mairelys Lemus-Rojas and Jere D. Odell have published "Creating Structured Linked Data to Generate Scholarly Profiles: A Pilot Project using Wikidata and Scholia" in the Journal of Librarianship and Scholarly Communication.

Here's an excerpt:

INTRODUCTION Wikidata, a knowledge base for structured linked data, provides an open platform for curating scholarly communication data. Because all elements in a Wikidata entry are linked to defining elements and metadata, other web systems can harvest and display the data in meaningful ways. Thus, Wikidata has the capacity to serve as the data source for faculty profiles. Scholia is an example of how third-party tools can leverage the power of Wikidata to provisde faculty profiles and bibliographic, data-driven visualizations. DESCRIPTION OF PROGRAM In this article, we share our methods for contributing to Wikidata and displaying the data with Scholia. We deployed these methods as part of a pilot project in which we contributed data about a small but unique school on the Indiana University-Purdue University Indianapolis (IUPUI) campus, the IU Lilly Family School of Philanthropy. NEXT STEPS Following the completion of our pilot project, we aim to find additional methods for contributing large data collections to Wikidata. Specifically, we seek to contribute scholarly communication data that the library already maintains in other systems. We are also facilitating Wikidata edit-a-thons to increase the library’s familiarity with the knowledge base and our capacity to contribute to the site.

"Analysis of 2018 International Linked Data Survey for Implementers"

has published "Analysis of 2018 International Linked Data Survey for Implementers" in the Code4Lib Journal.

Here's an excerpt:

A total of 143 institutions in 23 countries responded to one or more of the surveys. This analysis covers the 104 linked data projects or services described by the 81 institutions which responded to the 2018 survey—those that publish linked data, consume linked data, or both. This article provides an overview of the linked data projects or services institutions have implemented or are implementing; what data they publish and consume; the reasons given for implementing linked data and the barriers encountered; and some advice given by respondents to those considering implementing a linked data project or service. Differences with previous survey responses are noted, but as the majority of linked projects and services described are either not yet in production or implemented within the last two years, these differences may reflect new trends rather than changes in implementations.

"Stanford Libraries Awarded $4 Million Grant to Implement Linked Data Metadata Environment"

The Stanford Libraries have released "Stanford Libraries Awarded $4 Million Grant to Implement Linked Data Metadata Environment."

Here's an excerpt:

A proposal to dramatically shift how libraries create metadata and greatly improve how users discover library holdings has been accepted and awarded to Stanford Libraries by The Andrew W. Mellon Foundation. In partnership with the libraries of Cornell, Harvard and the University of Iowa, Stanford will lead the effort to integrate library data into the Web, in a semantic way, so it can be discovered intelligently in Web searches as well as in a library’s catalogue.

"DIY DOI: Leveraging the DOI Infrastructure to Simplify Digital Preservation and Repository Management"

Kyle Banerjee and David Forero have published "DIY DOI: Leveraging the DOI Infrastructure to Simplify Digital Preservation and Repository Management" in Code4Lib Journal.

Here's an excerpt:

This article describes methods for how staff with modest technical expertise can leverage the DOI (Digital Object Identifier) infrastructure in combination with third party storage and preservation solutions to build safer, more useful, and easier to manage repositories at much lower cost than is normally possible with standalone systems. It also demonstrates how understanding the underlying mechanisms and questioning the assumptions of technology metaphors such as filesystems can lead to seeing and using tools in new and more powerful ways.

"Reminiscing About 15 Years of Interoperability Efforts"

Herbert Van de Sompel and Michael L. Nelson have published "Reminiscing About 15 Years of Interoperability Efforts" in D-Lib Magazine.

Here's an excerpt:

Over the past fifteen years, our perspective on tackling information interoperability problems for web-based scholarship has evolved significantly. In this opinion piece, we look back at three efforts that we have been involved in that aptly illustrate this evolution: OAI-PMH, OAI-ORE, and Memento. Understanding that no interoperability specification is neutral, we attempt to characterize the perspectives and technical toolkits that provided the basis for these endeavors. With that regard, we consider repository-centric and web-centric interoperability perspectives, and the use of a Linked Data or a REST/HATEAOS technology stack, respectively. We also lament the lack of interoperability across nodes that play a role in web-based scholarship, but end on a constructive note with some ideas regarding a possible path forward.

Linked Archival Metadata: A Guidebook (Version 0.99)

Eric Lease Morgan and LiAM have released Linked Archival Metadata: A Guidebook (Version 0.99).

Here's an excerpt:

Linked data is a process for embedding the descriptive information of archives into the very fabric of the Web. By transforming archival description into linked data, an archivist will enable other people as well as computers to read and use their archival description, even if the others are not a part of the archival community. The process goes both ways. Linked data also empowers archivists to use and incorporate the information of other linked data providers into their local description. This enables archivists to make their descriptions more thorough, more complete, and more value-added. For example, archival collections could be automatically supplemented with geographic coordinates in order to make maps, images of people or additional biographic descriptions to make collections come alive, or bibliographies for further reading.

"Crafting Linked Open Data for Cultural Heritage: Mapping and Curation Tools for the Linked Jazz Project"

M. Cristina Pattuelli, Matt Miller, Leanora Lange, Sean Fitzell, and Carolyn Li-Madeo have published "Crafting Linked Open Data for Cultural Heritage: Mapping and Curation Tools for the Linked Jazz Project" in the latest issue of Code4Lib Journal.

Here's an excerpt:

This paper describes tools and methods developed as part of Linked Jazz, a project that uses Linked Open Data (LOD) to reveal personal and professional relationships among jazz musicians based on interviews from jazz archives. The overarching aim of Linked Jazz is to explore the possibilities offered by LOD to enhance the visibility of cultural heritage materials and enrich the semantics that describe them. While the full Linked Jazz dataset is still under development, this paper presents two applications that have laid the foundation for the creation of this dataset: the Mapping and Curator Tool, and the Transcript Analyzer. These applications have served primarily for data preparation, analysis, and curation and are representative of the types of tools and methods needed to craft linked data from digital content available on the web. This paper discusses these two domain-agnostic tools developed to create LOD from digital textual documents and offers insight into the process behind the creation of LOD in general.

"Linking Things on the Web: A Pragmatic Examination of Linked Data for Libraries, Archives and Museums"

Ed Summers and Dorothea Salo have self-archived "Linking Things on the Web: A Pragmatic Examination of Linked Data for Libraries, Archives and Museums" in arXiv.org.

Here's an excerpt:

The Web publishing paradigm of Linked Data has been gaining traction in the cultural heritage sector: libraries, archives and museums. At first glance, the principles of Linked Data seem simple enough. However experienced Web developers, designers and architects who attempt to put these ideas into practice often find themselves having to digest and understand debates about Web architecture, the semantic web, artificial intelligence and the philosophical nature of identity. In this paper I will discuss some of the reasons why Linked Data is of interest to the cultural heritage community, what some of the pain points are for deploying it, and characterize some pragmatic ways for cultural heritage organizations to realize the goals of Linked Data with examples from the Web we have today.

"Twenty-Five Shades of Greycite: Semantics for Referencing and Preservation"

Phillip Lord and Lindsay Marshall have self-archived "Twenty-Five Shades of Greycite: Semantics for Referencing and Preservation" in arXiv.org .

Here's an excerpt:

Semantic publishing can enable richer documents with clearer, computationally interpretable properties. For this vision to become reality, however, authors must benefit from this process, so that they are incentivised to add these semantics. Moreover, the publication process that generates final content must allow and enable this semantic content. Here we focus on author-led or "grey" literature, which uses a convenient and simple publication pipeline. We describe how we have used metadata in articles to enable richer referencing of these articles and how we have customised the addition of these semantics to articles. Finally, we describe how we use the same semantics to aid in digital preservation and non-repudiability of research articles

"Designing the W3C Open Annotation Data Model"

Robert Sanderson, Paolo Ciccarese, and Herbert Van de Sompel have self-archived "Designing the W3C Open Annotation Data Model" in arXiv.org.

Here's an excerpt:

The Open Annotation Core Data Model specifies an interoperable framework for creating associations between related resources, called annotations, using a methodology that conforms to the Architecture of the World Wide Web. Open Annotations can easily be shared between platforms, with sufficient richness of expression to satisfy complex requirements while remaining simple enough to also allow for the most common use cases, such as attaching a piece of text to a single web resource. This paper presents the W3C Open Annotation Community Group specification and the rationale behind the scoping and technical decisions that were made. It also motivates interoperable Annotations via use cases, and provides a brief analysis of the advantages over previous specifications.
