"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.

"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.

"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.

"Linked Data Services for Theses and Dissertations"

Thomas Johnson and Michael Boock have self-archived "Linked Data Services for Theses and Dissertations" in ScholarsArchive at Oregon State University.

Here's an excerpt:

This paper details work at Oregon State University to create a Linked Dataset covering the University's theses and dissertations. Using data from existing MARC and Qualified Dublin Core records, we have established a process and model for crosswalking data from existing records into a variety of Semantic Web vocabularies. Our approach is to create basic services on a dedicated thesis and dissertation interface, incrementally extending those available through our institutional repository. We describe services implemented, those in progress and plans for continued work. We also address the limitations of our existing metadata and resulting challenges in crosswalking and interoperability.

Open Annotation Core Data Model

The Open Annotation Collaboration has released the draft "Open Annotation Core Data Model."

Here's an excerpt:

The Open Annotation Core Data Model specifies an interoperable framework for creating associations between related resources, annotations, using a methodology which 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.

An Annotation is considered to be a set of connected resources, including a body and target, and conveys that the body is somehow about the target. The full model supports additional functionality, enabling semantic tagging, embedding content, selecting segments of resources, choosing the appropriate representation of a resource and providing styling hints for consuming clients.

Linked Data for Libraries, Museums, and Archives: Survey and Workshop Report

The Council on Library and Information Resources has released Linked Data for Libraries, Museums, and Archives: Survey and Workshop Report.

Here's an excerpt:

In June 2011, Stanford University hosted a group of librarians and technologists to examine issues and challenges surrounding the use of linked data for library applications. This report summarizes the activities and discussions that took place during the workshop, describes what came out of the workshop, outlines next steps identified by the participants, and provides contextual and background information, including preliminary reports and biographies of workshop participants. The workshop report was produced and edited by the participants and staff at Stanford University Libraries.

As background for workshop participants, CLIR commissioned Jerry Persons, technology analyst at Knowledge Motifs and Chief Information Architect emeritus at Stanford, to produce a survey of the linked-data landscape, and the projects and individuals associated with it. The survey focuses on the practical aspects of understanding and applying linked data practices and technologies to the metadata and content of libraries, museums, and archives. There are numerous links in the report and the survey that lead readers to many other sources and examples regarding the use of linked data methods.
