This document summarizes the highs and lows of library linked data projects. It discusses two UK projects that exposed library catalog and archive data as linked open data (LOD), including modeling the data as RDF, transforming it, and loading it into a triplestore. It highlights the benefits of LOD like easier data integration and discovery. However, it also notes challenges like steep learning curves, complexity of archival data, issues of scalability, provenance and licensing.

This presentation looks back at several efforts, conducted in the past fifteen years, aimed at establishing interoperability for web-based scholarly communication. It tries to characterize the perspectives/approaches taken by these efforts and, based upon that, proposes an HATEOS-based approach to interlink scholarly nodes on the web. This was first presented at the Research Data Alliance meeting in Paris, France, September 22 2015.

Linked Data Implementations—Who, What and Why?OCLC
Presented at the CNI Spring Membership Meeting in San Antonio, Texas 4 April 2016. OCLC Research conducted an International Linked Data Survey for Implementers in 2014 and 2015, receiving responses from a total of 90 institutions in 20 countries. In the 2015 survey, 112 projects or services that consumed or published linked data were described (compared to 76 in 2014). This presentation summarizes the 2015 survey results: 1) which institutions have implemented or are implementing linked data; 2) what linked data sources institutions are consuming, and why; 3) what institutions are publishing, and why; 4) barriers and advice from the implementers.

Do the LOCAH-Motion: How to Make Bibliographic and Archival Linked DataAdrian Stevenson
Presentation given at the Dev8d Developer Days event at the University of London Students Union, London, UK on 15th February 2011.
The talk was primarily aimed at developers with the assumption that they knew a bit about RDF and Linked Data, so it doesn’t discuss these except in passing. I was mainly trying to give some specifics on the technicalities involved, and what platforms and tools we’re using, so people can follow the same path if they wanted.

Overview of resource discovery in libraries today. Presented at the CIG Scotland seminar 'Resource Discovery : from catalogues to discovery services' at the National Library of Scotland, Edinburgh, 21st March 2018
Repositories are systems to safely store and publish digital objects and their descriptive metadata. Repositories mainly serve their data by using web interfaces which are primarily oriented towards human consumption. They either hide their data behind non-generic interfaces or do not publish them at all in a way a computer can process easily. At the same time the data stored in repositories are particularly suited to be used in the Semantic Web as metadata are already available. They do not have to be generated or entered manually for publication as Linked Data. In my talk I will present a concept of how metadata and digital objects stored in repositories can be woven into the Linked (Open) Data Cloud and which characteristics of repositories have to be considered while doing so. One problem it targets is the use of existing metadata to present Linked Data. The concept can be applied to almost every repository software. At the end of my talk I will present an implementation for DSpace, one of the software solutions for repositories most widely used. With this implementation every institution using DSpace should become able to export their repository content as Linked Data.
Expanded presentation from 2012 Charleston Conference on how to complete missing metadata in certain EDS records by obtaining it from WorldCat to ensure linking to desired item held by local library.
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.

IFLA LIDASIG Open Session 2017: Introduction to Linked DataLars G. Svensson
At the IFLA Linked Data Special Interest Group open session in Wroclaw we briefly introduced the mission of the SIG and then went on to a brief introduction to what linked data is and why that topic is important to libraries.
The presentation was held jointly by Astrid Verheusen (general introduction to the SIG) and Lars G. Svensson (introduction to Linked Data)
Delivered by Peter Burnhill, Director of EDINA, at the PRELIDA Consolidation and Dissemination workshop on 17/18 October 2014 (http://prelida.eu/consolidation-workshop).
Summary: The web changes over time, and significant reference rot inevitably occurs. Web archiving delivers only a 50% chance of success. So in addition to the original URI, the link should be augmented with temporal context to increase robustness.

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

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter 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.

2. LOCAH and Linking Lives Projects
• Linked Open Copac and Archives Hub
– Funded by #JiscEXPO 2/10 ‘Expose’ call
• 1 year project. Started August 2010
– Partners & Consultants:
• UKOLN, Mimas, Eduserv, Talis, OCLC, Ed Summers
– http://blogs.ukoln.ac.uk/locah/
• Linking Lives
– JISC funded for ‘Mimas Enhancements’
– 11 month project. Started Sept 2011
– http://archiveshub.ac.uk/linkinglives/
3. Archives Hub and Copac
• UK National Data Services based at Mimas
• Copac provides access to the merged library
catalogues of libraries throughout the
UK, including all national libraries
– http://copac.ac.uk
• Archives Hub is an aggregation of archival
descriptions from archive repositories
across the UK
– http://archiveshub.ac.uk
4. LOCAH Outputs
• Expose Archives Hub &Copac
data as Linked Data
• Create a prototype visualisation
• Report on opportunities and
barriers
5. How do we expose the Linked Data?
1. Model our ‘things’ into RDF
2. Transform the existing data into RDF/XML
3. Enhance the data
4. Load the RDF/XML into a triple store
5. Create Linked Data Views
6. Document the process, opportunities and
barriers on LOCAH Blog
6. Modelling ‘things’ into RDF
• Copac data in ‘Metadata Object Description
Schema’ MODS XML form
– http://www.loc.gov/standards/mods/
• Take a step back from the data format
– What is MODS document “saying” about
“things”?
– What questions do we want to answer about
those “things”?
7. Aggregated Data
• Copac MODS record = an aggregated book
record
– e.g. ‘Bleak House’ held at 10 different libraries
– Copac ‘merges’ the descriptions from 8 of them
– 2 are not consistent with the rest, so they remain
as stand-alone descriptions
– End result: have 3 records for ‘Bleak House’
– Not talking about ‘a book’
8. URI Patterns
• Need to decide on patterns for URIs we generate
• Following guidance from W3C ‘Cool URIs for the Semantic
Web’ and UK Cabinet Office ‘Designing URI Sets for the UK
Public Sector’
http://data.archiveshub.ac.uk/id/findingaid/gb1086skinner
‘thing’ URI
redirects to …
http://data.archiveshub.ac.uk/doc/findingaid/gb1086skinner
document URI
http://www.w3.org/TR/cooluris/
http://www.cabinetoffice.gov.uk/resource-library/designing-uri-sets-uk-public-sector
9. Vocabularies
• Using existing RDF vocabularies:
– DC, SKOS, FOAF, BIBO, WGS84
Geo, Lexvo, ORE, LODE, Event and Time
Ontologies
• Define additional RDF terms where required,
– copac:BibiographicResource
– copac:Creator
• It can be hard to know where to look for
vocabs and ontologies
11. Transforming into RDF/XML
• Transform EAD and MODS to RDF/XML based
on our models
– Copac: created in-house Java transformation
program
– Hub: XSLT Stylesheet
• Load RDF/XML into a triple store
12. We’re Linking Data!
• If something is identified, it can be linked to
• We take items from our datasets and link them
to items from other datasets
BBC
Copac
VIAF
DBPedia
GeoNames
Archives Hub
13. Enhancing our data
• Already have some links:
– Time - reference.data.gov.ukURIs
– Location - UK Postcodes URIs and Ordnance
Survey URIs
– Names - Virtual International Authority File
• VIAF matches and links widely-used authority
files - http://viaf.org/
– Names - DBPedia
• Also looking at:
– Subjects - Library Congress Subject Headings
and DBPedia
17. Visualisation Prototype
Using Timemap –
– Googlemaps and
Simile
– http://code.google.com/p/time
map/
Early stages with this
Will give location and
‘extent’ of archive.
Will link through to
Archives Hub
20. Highs of Linked Data
• API based mashupswork against a fixed
set of data sources
• Hand crafted by humans
• Don’t integrate well
• Linked Data promises an unbound global
data space
• Easy dataset integration
• Generic ‘mesh-up’ tools
25. Scalability / Provenance
• Same issue with attribution
• Solutions: Named graphs? Quads?
Example by Bradley Allen, Elsevier at
• Best Practice LOD LAM Summit, SF, USA, June 2011
26. Licensing
• Ownership of data often not clear
• Difficult to track attribution and
provenance
• CC0 for Archives Hub and
Copacdata test sets
27. Sustainability
• Can you rely on data sources long-term?
• Ed Summers at the Library of Congress
created http://lcsh.info
• Linked Data interface for LOC subject
headings
• People started using it
29. Linked Data the Future for Libraries?
• Enables ‘straightforward’ integration of
wide variety of data sources
• Library data can ‘work harder’
• New channels into your data
• Researchers are more likely to discover
sources
• ‘Hidden' collections become of the Web

In hypertext web sites it is considered generally rather bad etiquette not to link to related external material. The value of your own information is very much a function of what it links to, as well as the inherent value of the information within the web page. So it is also in the Semantic Web.Remember, this is about machines linking – machines need identifiers; humans generally know when something is a place or when it is a person. BBC + DBPedia + GeoNames + Archives Hub + Copac + VIAF = the Web as an exploratory spaceUsers very interested in related materials acc to Terry Catapano at SAA 2011. LD can really help with this.

Steep learning curve: - RDF Linked Data modelingterminology - Lack of archive domain examples – though you now have LOCAH! - Certain level of expertise neededDirty Data - Joe Bloggs and others’ rather than just a name, or where the access points do not have rules or a source associated with them. - Extent data highly variableComplexity - “lower level” units interpreted in context of the higher levels of description - Arguably “incomplete” without the contextual data.Relations are asserted, e.g. member-of/component-ofBut there is no requirement or expectation that data consumers will follow the links describing the relations
