About the Webinar
The library and cultural institution communities have generally accepted the vision of moving to a Linked Data environment that will align and integrate their resources with those of the greater Semantic Web. But moving from vision to implementation is not easy or well-understood. A number of institutions have begun the needed infrastructure and tools development with pilot projects to provide structured data in support of discovery and navigation services for their collections and resources.
Join NISO for this webinar where speakers will highlight actual Linked Data projects within their institutions—from envisioning the model to implementation and lessons learned—and present their thoughts on how linked data benefits research, scholarly communications, and publishing.

TPDL2013 tutorial linked data for digital libraries 2013-10-22jodischneider
Tutorial on Linked Data for Digital Libraries, given by me, Uldis Bojars, and Nuno Lopes in Valletta, Malta at TPDL2013 on 2013-10-22.
http://tpdl2013.upatras.gr/tut-lddl.php
This half-day tutorial is aimed at academics and practitioners interested in creating and using Library Linked Data. Linked Data has been embraced as the way to bring complex information onto the Web, enabling discoverability while maintaining the richness of the original data. This tutorial will offer participants an overview of how digital libraries are already using Linked Data, followed by a more detailed exploration of how to publish, discover and consume Linked Data. The practical part of the tutorial will include hands-on exercises in working with Linked Data and will be based on two main case studies: (1) linked authority data and VIAF; (2) place name information as Linked Data.
For practitioners, this tutorial provides a greater understanding of what Linked Data is, and how to prepare digital library materials for conversion to Linked Data. For researchers, this tutorial updates the state of the art in digital libraries, while remaining accessible to those learning Linked
Data principles for the first time. For library and iSchool instructors, the tutorial provides a valuable introduction to an area of growing interest for information organization curricula. For digital library project managers, this tutorial provides a deeper understanding of the principles of Linked Data, which is needed for bespoke projects that involve data mapping and the reuse of existing metadata models.

Libraries around the world have a long tradition of maintaining authority files to assure the consistent presentation and indexing of names. As library authority files have become available online, the authority data has become accessible -- and many have been published as Linked Open Data (LOD) -- but names in one library authority file typically had no link to corresponding records for persons and organizations in other library authority files. After a successful experiment in matching the Library of Congress/NACO authority file with the German National Library's authority file, an online system called the Virtual International Authority File was developed to facilitate sharing by ingesting, matching, and displaying the relations between records in multiple authority files.
The Virtual International Authority File (VIAF) has grown from three source files in 2007 to more than two dozen files today. The system harvests authority records, enhances them with bibliographic information and brings them together into clusters when it is confident the records describe the same identity. Although the most visible part of VIAF is a HTML interface, the API beneath it supports a linked data view of VIAF with URIs representing the identities themselves, not just URIs for the clusters. It supports names for person, corporations, geographic entities, works, and expressions. With English, French, German, Spanish interfaces (and a Japanese in process), the system is used around the world, with over a million queries per day.
Speaker
Thomas Hickey is Chief Scientist at OCLC where he helped found OCLC Research. Current interests include metadata creation and editing systems, authority control, parallel systems for bibliographic processing, and information retrieval and display. In addition to implementing VIAF, his group looks into exploring Web access to metadata, identification of FRBR works and expressions in WorldCat, the algorithmic creation of authorities, and the characterization of collections. He has an undergraduate degree in Physics and a Ph.D. in Library and Information Science.
As described in the April NISO/DCMI webinar by Dan Brickley, schema.org is a search-engine initiative aimed at helping webmasters use structured data markup to improve the discovery and display of search results. Drupal 7 makes it easy to markup HTML pages with schema.org terms, allowing users to quickly build websites with structured data that can be understood by Google and displayed as Rich Snippets.
Improved search results are only part of the story, however. Data-bearing documents become machine-processable once you find them. The subject matter, important facts, calendar events, authorship, licensing, and whatever else you might like to share become there for the taking. Sales reports, RSS feeds, industry analysis, maps, diagrams and process artifacts can now connect back to other data sets to provide linkage to context and related content. The key to this is the adoption standards for both the data model (RDF) and the means of weaving it into documents (RDFa). Drupal 7 has become the leading content platform to adopt these standards.
This webinar will describe how RDFa and Drupal 7 can improve how organizations publish information and data on the Web for both internal and external consumption. It will discuss what is required to use these features and how they impact publication workflow. The talk will focus on high-level and accessible demonstrations of what is possible. Technical people should learn how to proceed while non-technical people will learn what is possible.

Librarian use of authority files dates back to Callimachus and the Great Library of Alexandria around 300 BC. With the evolution of powerful computerized searching and retrieval systems, authority data appears to some to have outlived its usefulness. However, the Semantic Web provides an opportunity to use authority data to enable computers to search, aggregate, and combine information on the Web. Join this webinar to learn about the amazing services that can result when the rich data included in name authority files, and other standardized vocabularies are linked via the Semantic Web.
About the Webinar
In May 2012, the Library of Congress announced a new modeling initiative focused on reflecting the MARC 21 library standard as a Linked Data model for the Web, with an initial model to be proposed by the consulting company Zepheira. The goal of the initiative is to translate the MARC 21 format to a Linked Data model while retaining the richness and benefits of existing data in the historical format.
In this webinar, Eric Miller of Zepheira will report on progress towards this important goal, starting with an analysis of the translation problem and concluding with potential migration scenarios for a broad-based transition from MARC to a new bibliographic framework.
The Impact of Linked Data in Digital Curation and Application to the Catalogu...Hong (Jenny) Jing
(Full version of the presentation: https://www.youtube.com/watch?v=WS9Svbmp-YY)
Information organization and systems in libraries are in a state of significant flux. In systems there is a shift to XML and RDF-based schemas and ontologies while resource description content standards have changed from AACR2 to RDA. A move from MARC to BIBFRAME and other linked data applications is on the horizon. Linked data and the semantic web have become buzzwords, but what is linked data and why it is important for librarians? How can we use it in digital curation? What can libraries do now to “prepare” for this change in their current practice?
In light of these questions, the panel presentation will discuss two projects. First, there will be coverage of a sample project using the Fedora-based open source framework, Islandora to demonstrate the concepts of connecting related data across the Web with URIs, HTTP and RDF. The second half of the presentation will describe how a consortia has taken a holistic approach to writing an RDA workflow to help front-line cataloguers develop a wider perspective when it comes to resource description (creating more structured, future compatible metadata). Up for discussion: the current state and future possibilities of library metadata with a focus on the implications of linked data.

This paper surveys the landscape of linked open data projects in cultural heritage, exam- ining the work of groups from around the world. Traditionally, linked open data has been ranked using the five star method proposed by Tim Berners-Lee. We found this ranking to be lacking when evaluating how cultural heritage groups not merely develop linked open datasets, but find ways to used linked data to augment user experience. Building on the five-star method, we developed a six-stage life cycle describing both dataset development and dataset usage. We use this framework to describe and evaluate fifteen linked open data projects in the realm of cultural heritage.
The explosion in growth of the Web of Linked Data has provided, for the first time, a plethora of information in disparate locations, yet bound together by machine-readable, semantically typed relations. Utilisation of the Web of Data has been, until now, restricted to the members of the community, eating their own dogfood, so to speak. To the regular web user browsing Facebook and watching YouTube, this utility is yet to be realised. The primary factor inhibiting uptake is the usability of the Web of Data, where users are required to have prior knowledge of elements from the Semantic Web technology stack. Our solution to this problem is to hide the stack, allowing end users to browse the Web of Data, explore the information it contains, discover knowledge, and use Linked Data. We propose a template-based visualisation approach where information attributed to a given resource is rendered according to the rdf:type of the instance.
The Canadian Linked Data Initiative: Charting a Path to a Linked Data FutureNASIG
As libraries prepare to shift away from MARC to a linked data framework, new convergences in the metadata production activities of our libraries' technical services units, special collections, and digital libraries are becoming possible. In September 2015, the Canadian Linked Data Initiative (CLDI) was formed to leverage the existing collaboration between the Technical Services departments of Canada’s top 5 research libraries and the Library and Archives of Canada. Working cooperatively, our objective is to provide a path to linked data readiness for our institutions and leadership for the adoption of linked data by libraries across Canada. To achieve this goal, partner libraries are working across departments and institutions to create new workflows and tools and adapt to a new conceptual understanding of descriptive metadata. This presentation is a preliminary report on the progress made in five key areas of interest: digital collections, education and training, MARC record enhancement, evaluation of linked data tools and vendor supplied metadata. Building on existing initiatives, the CLDI is investigating the potential of integrating linked data elements into digitized collections, as well as MARC-based bibliographic and authority records, with the aim of fostering new and interesting pathways for resource discovery. To strengthen and expand the professional knowledge of staff, partner institutions are collaborating in the production of educational and training materials related to linked data principles and practices. The evaluation and potential development of linked data tools is another area of concentration. Finally, with the goal of changing workflows upstream, the CLDI is working to engage publishers and vendors in the linked data conversation. In addition to reporting on the work undertaken in the first year of the project, this presentation will also cover lessons learned and outline some of the new opportunities gained from working on a collaborative project that spans across multiple boundaries.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

81. Project Overview
• Investigating the application of Linked Open Data
to enhance the discovery and visibility of digital
cultural heritage materials.
• Build new methods of connecting cultural data.
• Uncover meaningful connections between
documents and data related to the personal and
professional lives of musicians who often practice
in rich and diverse social networks.
Professor Cristina Pattuelli at the Pratt Institute School of Library Information Science is the
director of the project which began in 2011.
82. Linked Data Now!
Why?
• Bootstrap your project with existing data.
• Highlights knowledge you have created and
knowledge that is missing.
• Facilitates sharing, but also growing your own
project.
83. Bootstrapping – Identifying
Research Question
How can we discover and analyze
the rich and diverse network of
relationships between jazz
musicians?
Primary Sources
Oral history interview transcripts
of jazz musicians.
84. Bootstrapping – Identifying
Research Question
How can we discover and analyze
the rich and diverse network of
relationships between jazz
musicians?
Primary Sources
Oral history interview transcripts
of jazz musicians.
We need to know the names
(and variants) of jazz
musicians in a structured
controlled vocabulary.
85. Bootstrapping – Identifying
Charlie Parker
Many different LOD datasets contain this
information. We need to access, query and link it
for only jazz related individuals.
87. Bootstrapping – Querying
• Processing the DBpedia dataset resulted in around
9,000 URIs.
– DBpedia is fluid! After each release (currently 3.9) we
reprocess the files resulting in the addition of 500-700
URIs.
• We now have a name directory, but we want
additional forms of personal names. To accomplish
this we try mapping to Library of Congress.
• Matching DBpedia and LC URIs is not automatic.
88. Bootstrapping – Mapping
• We matched identities based on:
• Name
• Life Dates
• White listed words found in sources
(http://www.loc.gov/mads/rdf/v1#Source)
• Reconciling authorities is difficult!
• Use others work: http://viaf.org/viaf/data/
• But don’t discount your own processes.
• Using our relatively simple process we
were able to match about 1500 more URIs
than VIAF.org.
• This is due to a smaller domain (jazz).
Our name directory creation and authority
matching is documented:
https://github.com/thisismattmiller/linkedjazz-name-directory
90. Bootstrapping – Review
• Start small, think big.
– Specific subject domain.
– Large infrastructure not required (triple stores, etc.)
• Can get started with extract files and python scripting.
• Reuse as much as possible, but try new processes
leveraging domain specificity.
• Always be curating, use tools to facilitate process but
a human hand is often required.
91. Applying the Data
• Use the name directory to locate individuals in
the interview transcript.
• This project phase involves 50 transcripts.
• Because the names are tied to URIs we can
infer a relationship triple between two
individuals.
<foaf:Person> <rel:knowsOf> <foaf:Person>
94. Transcript Analyzer
• An interface to curate the transcripts and verify
detected names.
• Implements off the shelf NLP (NLTK) to attempt
to locate additional names not in our directory as
well as corporate names and locations.
• Global rule system, as we process more
transcripts the system is being trained.
• Using URIs to represent entities we can quickly
see where we are discovering new material.
– 50 Transcripts
• 1800 person entities tagged.
• 250 names tagged without authoritative URI.
– Knowledge Creation
95. New Dataset
• We have created a new LOD dataset now of
jazz musician’s relationships.
• Our next steps are:
– Visualize.
– Further qualify the rel:knowsOf relationships.
– Provide access to the data created.
97. Qualify Relationships – 52nd St.
• Recruit jazz experts and enthusiasts to help
categorize relationships based on transcript
text.
• We use existing vocabularies to build the data
set: Foaf, Relationship Vocabulary, Music
Ontology
• The interface is critical for crowdsourcing tools,
we work with user experience experts and
conduct user studies to refine our public facing
tools
99. Provide Access
• We provide a SPARQL endpoint.
• But also a traditional API:
– http://linkedjazz.org/api/
– Can return:
• JSON
• N-Triples
• Gephi graph files (GXEF)
100. Learn and Grow as a Team
• Experience through doing.
• Empower graduate
students with skills and
practical experience
working with a LOD
project.
• Use the project as a
vehicle to make intra- and
inter-intuitional
collaborations.
Linked Jazz Team July 2013
101. Next Steps
• Refactor our prototype tools into sustainable open
source projects.
• Redesign 52nd St. based on user study groups.
• Work on emerging collaborations with Jazz Centers.

105. How it Started
•
•
•
•
Conferences and “buzz”
Curiousity and professional development
Exploration and pilot project
Compelling results; sharing impact of what
we’ve learned
• Assessment
• Much more to do...
106. Current Practice
• Data (or metadata) encapsulated in records
• Records contained in collections
• Very few links are created within and/or across
collections
• Links have to be manually created
• Existing links do not specify the nature of the
relationships among records
This structure hides potential links within and
across collections
107. What we can do with linked data
•
•
•
•
•
•
Free data from silos
Expose relationships
Powerful, seamless, interlinking of our data
Users interact or query data in new ways
Search results would be more precise
Data can be easily repurposed
108. Making the Case for Linked Data in
Academic Library Digital Collections
– Problem: Rich metadata is being lost in dumbed down
DC records
– Issue: Investment and resource allocation (Item-level
philosophy)
– Goal: Increased: exposure, collaboration, and
openness
– Outcome: Increased discovery and user-focus
109. Gaining Buy In
Administration
• Innovative project, high impact
• Pilot, experiment, learn by doing, share results
Staff
• We already have the metadata; We need to
transform them into triples
• Managing change
113. Implications (Internal)
• Cross-unit collaboration is necessary
• Staff expertise will evolve
• Staff roles will change to accommodate new /
parallel workflow
• Data clean-up will be an investment
• Management of data becomes critical
• Discovery issues = user interfaces still need
development
114. Implications (External)
• Publish data from our collections in the Linked
Data Cloud to improve discoverability and
connections with other related data sets on
the Web
• Sharing data in new ways with new partners
may raise new issues
• Need to engage with linked data community
for technologies, tools, best practices, and to
demand library vendor support for LOD.
115. UNLV Linked Data Project
Goals:
• Study the feasibility of developing a common
process that would allow the conversion of our
collection records into linked data preserving
their original expressivity and richness
• Publish data from our collections in the Linked
Data Cloud to improve discoverability and
connections with other related data sets on the
Web

118. Prepare / Export Data
Technology: CONTENTdm
• Increase consistency across collections:
– metadata element labels
– use of CV, share local CVs
– etc.
• Export data as spreadsheet
Create mapping between metadata elements and
EDM model predicates
119. OpenRefine
• Open source
• It is a server – can communicate with other
datasets via http
• Open Refine and its RDF extension should be
installed
Screenshots to show some of the functions we have
used

148. Next steps for the UNLV project
• Transform all digital collections into linked data
(parallel structure)
• Increase linkage with other datasets
• Design interfaces to access and display our data
and related data from other datasets
• Evaluate alternative interfaces from user’s
perspective
• Produce a cost benefit analysis to inform future
plans for the development of digital collections
