Building more complete and linked GLAM datasets: The Smithsonian’s (In)Visible Women’s Project
Monday September 28, 2026 10:15am - 10:45am EDT
TBA
The Smithsonian’s (In)Visible Women Project, based at the National Museum of the American Indian, is developing pan-institutional data practices within Wikidata to support the disambiguation of artists, designers, scientists, etc. documented across fourteen Smithsonian repositories. This work seeks to connect siloed internal collections information systems (ArchivesSpace, TMS, EMu, etc.), an issue that has compounded with gaps in existing authority identifier sources (LCNAF, ULAN, etc.) and historical Smithsonian information practices to obscure the achievements of women.

Our lightning talk will focus on our work to date and reflect on our successes, but also lessons learned from managing a collaborative, pan-institutional, linked data project. Specifically, we will discuss: 1) the process of developing our collaborative, Smithsonian-specific Wikidata data model; 2) the challenges we have encountered in existing Wikidata structures; 3) our approach to managing the privacy of those represented in Smithsonian datasets; and 4) the uptake of Wikidata editing by Smithsonian staff and our strategies to build Wikidata editing skillsets.

JCricket as an Operational Entity Editor for Shared Cataloguing
Monday September 28, 2026 10:45am - 11:15am EDT
TBA
The transition toward linked data environments, entity-based models, and interoperable metadata ecosystems is reshaping cataloguing into a dynamic, collaborative, and distributed practice based on shared cataloguing. To respond to this change, the Share Family community has developed JCricket, the Linked Data Entity Editor designed for collaboratively curating entities in a multi-institutional, shared space.
Drawing on over ten years of developments within the Share Family Ecosystem, this presentation will show the concrete implementation of JCricket and how it streamlines libraries’ operational workflows and real-world cataloguing practices. Through granular cataloguing, Provenance-based data management, and integrations with FOLIO and Alma library services platforms (and others to come), data entered in libraries’ ILS/LSP is reflected in the central Cluster Knowledge Base underlying JCricket and vice-versa. These new copy cataloguing features allow for a full roundtrip of data transitioning from record transfer workflows to collaborative, entity-based data management.
In JCricket, bibliographic entities are no longer isolated local records or static imported copies, but interconnected data objects continuously enriched, synchronised, corrected, and reused across institutions.
Since JCricket operates on a multi-Provenance dataset, its inherent complexity requires guidelines: a set of best practices is being elaborated to consolidate shared cataloguing workflows and ensure consistent data integration with external systems.

Once-in-an-Instance in BIBFRAME: Describing Manuscripts
Monday September 28, 2026 11:45am - 12:15pm EDT
TBA
Part of the task force for the second revision cycle of the Art and Rare Materials (ARM) BIBFRAME ontology extension, the Manuscripts Subteam has been working to define the role of unique items, such as manuscripts, within the conceptual framework BIBFRAME is built from. Describing manuscripts poses challenges as it requires sets of definitions that can be adapted to objects that, by definition, do not always fit in standardized categories. These unique works and the relationships they may have to other works must be described in such a way that their metadata remains unique but also serves discovery to other resources. Our goal is to extend the ontology to create a system that is flexible enough to be collapsed in on itself when the boundaries between work-instance-item are less distinct but also supports these distinctions where valuable.
This presentation will explore the meaning and ontological implications of "uniqueness," the overlapping definitions of manuscripts, and how some of the distinctive characteristics of manuscripts can be expressed within the BIBFRAME ontology.

Building the Bridge: How WorldCat is Evolving to Support MARC and BIBFRAME
Monday September 28, 2026 1:30pm - 2:00pm EDT
TBA
Libraries around the world are at various stages in their transition to BIBFRAME. Some are learning the impact and benefits of leveraging BIBFRAME data; many are experimenting with BIBFRAME data in their cataloging and discovery workflows; and others are ready to fully productionize BIBFRAME data across their metadata management ecosystems.

When it comes to widespread adoption and implementation, the need for scalable, consistent, and quality data becomes the cornerstone. And while the data formats and workflows evolve, the global infrastructure to support such an important transition already exists. For nearly 60 years, WorldCat has provided the foundation upon which the global library community creates, manages, and shares knowledge—evolving every step of the way as library collections and needs of the communities they serve change.

Building on OCLC’s history of collaboration with the library community on metadata management and linked data innovation, we’re excited to share the next phase of WorldCat’s evolution. In this presentation, we’ll share updates on WorldCat BIBFRAME interoperability, workflows for managing data in both MARC and BIBFRAME, and feedback from our latest library partnership on cataloging in BIBFRAME.

The Blue Core project successfully completed its prototype development in 2025, establishing a community-operated and owned BIBFRAME data store. This prototype has served as a critical testing environment for integration with two open-source linked data editors: Sinopia and Marva. Following comprehensive scalability testing, metadata operations validation, and integration assessments with local Library Services Platforms, the project has advanced to its second MVP (Minimum Viable Product) work cycle. The current MVP incorporates agentic AI capabilities designed to enhance cataloger workflows. The project team is now preparing for a phased BIBFRAME implementation scheduled to begin in early 2027. This session will provide an overview of the project's background, current development status, and planned future activities.

EMCO 101: Entity Management for Everyone
Monday September 28, 2026 2:30pm - 3:00pm EDT
TBA
The Program for Cooperative Cataloging (PCC) aims to reduce costs associated with producing bibliographic and authority records to support discovery within public catalogs. The PCC meets this aim by developing metadata application profiles and implementing an apprenticeship-style training scheme within its global membership. The PCC launched a new program in spring 2025, the Entity Management Cooperative (EMCO). The EMCO program aims to empower library staff to manage linked data entities from any source for use in descriptive metadata practices, thereby significantly lowering barriers for participating in the PCC, while fostering the development of the technical expertise needed to forge new paths for linked data adoption within the PCC as a whole. Working in communities of practice, participants have learned to create and describe linked data entities in ISNI, WorldCat Entities, and Wikidata. This panel brings together EMCO participants and organizers to explain why and how the EMCO program was created, explore its work and impact, and discuss what we have learned in our attempts during EMCO’s inaugural year to corral over 250 data enthusiasts into an organized program.

From Wikidata to Our Collection Management System: Automating GIS Import for Cultural Heritage Data
Monday September 28, 2026 3:10pm - 3:20pm EDT
TBA
Linking a place authority record to a usable geographic shape is often a manual, time-consuming step in collection management systems — yet the linked data is frequently already there. This lightning talk demos a small, open, dependency-free (Python standard library only) pipeline built for Axiell Collections at the Rijksmuseum, which takes a Wikidata QID, follows its OpenStreetMap relation (P402) or point coordinate (P625), fetches the geometry via Overpass, and converts it into a ready-to-import Axiell record — with no manual GIS work required.
The real value is in the edge cases: real OpenStreetMap and Wikidata data rarely behaves as cleanly as the happy path suggests, and this talk walks through a few concrete examples of how the pipeline handles them without silently producing a wrong result. It also processes hundreds of records in a single batch, with a clear audit trail of what needs human review. These are exactly the kinds of real-world data quirks any institution connecting Wikidata/OSM to a legacy collection system will run into.
Attendees will leave with a concrete, reusable pattern for this kind of linked-data-to-CMS pipeline, regardless of which collection management system they use.

What goes around comes around: Leveraging linked data in cataloging workflows
Monday September 28, 2026 3:20pm - 3:30pm EDT
TBA
The benefits of linked data in the cataloging community are often tied to improved search and discovery for library users, but in this lightning talk, I share a small use case of linked data also benefiting us, the catalogers creating the linked data. To tackle a backlog of CDs and vinyl requiring original cataloging at the UCLA Library, I worked with music catalogers to create a Python tool that could retrieve not only existing metadata from Discogs - a widely used crowdsourced music database - to generate a basic MARC record; the tool could also look beyond this database to incorporate authorized access points from the Library of Congress Name Authority File (LCNAF) by using identifiers across Discogs, Wikidata, and LCNAF - essentially, using the linked data that we've collectively created to reduce manual effort in cataloging work. This project thus highlights how the cataloging community's investment in linked data can benefit not just our users, but also ourselves, allowing us to leverage community-created data to enhance our own metadata workflows.

Naive Bibliometrics: The ongoing bibliometric impact of a racist article
Monday September 28, 2026 3:30pm - 4:00pm EDT
TBA
As part of two larger projects in 2025 I identified four articles about bibliometrics published in journals identified as sources of racial hereditarian research. These four articles are relatively insignificant in the larger bibliometrics literature, but they form a natural experiment for both testing the scope of what is available in the bibliometrics data sources and the impact of racial hereditarian research on bibliometrics as a field.

An outlier paper in the study is the most highly cited paper for all of the authors in the paper. While the total number of citations is small, the impact on these particular authors is large. This unique linked data set identifies a new problem with the naive use of citation counts as a basis of quality in scientific communication.

Passing the BF Vibe Check: A Workshop on Chat-Based BIBFRAME Creation
Monday September 28, 2026 4:00pm - 5:00pm EDT
TBA
This workshop introduces a pre-release version of BF Vibe Desktop, an application where catalogers describe a resource in chat and receive validated BIBFRAME to edit and download. The AI runs on your own computer, like any desktop program, and descriptions are never sent to a commercial AI service. BIBFRAME structure comes from templates modeled on Library of Congress patterns, and shared validation rules check the result, while every cataloging decision stays in human hands.

The session opens with a brief demonstration, followed by hands-on record creation and feedback. Participants will create BIBFRAME records from chat and edit the resulting Work and Instance. They can validate against profiles developed by the BIBFRAME Interoperability Group and review rule-backed repair suggestions. They can also inspect the pre-loaded validation rules and author their own, running both together against records. The session collects feedback to shape the version one release, guided by a broad question: does the application provide the right support, at the right moments, for catalogers new to BIBFRAME?

Please install and launch the application once before the session (first launch downloads a ~5 GB AI model).

Finding where to contribute on Wikidata with Dustpan and Broomstick
Tuesday September 29, 2026 9:30am - 10:00am EDT
TBA
Finding where to contribute on Wikidata isn't always straightforward, especially with structured and lexicographical data spread across multiple WikiProjects and languages. Identifying a gap, and knowing how to act on it, can be harder than making the edit itself.

This session introduces Dustpan and Broomstick, two tools developed by Wikicollabs that help contributors discover opportunities to improve Wikidata. Dustpan helps contributors find Items with missing information by selecting a WikiProject, a category of missing information, and, where available, an additional scope. For example, contributors working with WikiProject Sum of All Paintings can use Dustpan to find paintings that are missing information, such as the creator or material used. Broomstick focuses on lexicographical data, helping contributors uncover Lexemes that can be improved across different languages, including issues involving Senses, Forms, and misplaced statements.

Through live demonstrations, participants will see how finding a gap leads to a specific edit they can make on Wikidata. By the end of the session, participants will be able to use Dustpan and Broomstick to find where to contribute on Wikidata. We also welcome suggestions for which WikiProjects and languages the tools should support next.

Lexipedia - linking data to process for design and description
Tuesday September 29, 2026 10:40am - 10:50am EDT
TBA
For over 50 years, lawyers have used process models to describe how information and decisions move. Lexipedia, developed by the Center for Civic Innovation and the University of Virginia, describes legal processes using modern procedural standards such as BPMN (Business Process Model Notation) and Petri Nets.

Process models describe how things happen, but offer no convenient discovery mechanism. Lexipedia's latest release adds linking to pull Wikidata entries in directly, plus a QuickStatements generator for the Lexipedia Wikibase — where laws, case law, and other content not yet ready for the Wikidata ecosystem can await community review.

Linked data adds further value through specific legal ontologies: Akoma Ntoso, which correlates legal axioms across global legal systems, and deontic logic, which defines logic from language.

Cross-referencing legal concepts is self-explanatory; deontic logic is more nuanced. For example, if one MUST do something, it's implied there's a consequence for not doing it. In legal texts these statements often aren't adjacent, and get left out of models. Describing content with deontic logic lets us run a baseline "legal linting" pass that improves models and simplifies review.

Reduced Fuzziness in Semantic Kompakkt 3D Object Viewer through Extensive Data Modelling in Wikibase
Tuesday September 29, 2026 11:30am - 12:00pm EDT
TBA
Designed for digital humanities research, Semantic Kompakkt is a free, open-source platform for exploring and semantically annotating visual media in an interconnected open-data environment. Semantic Kompakkt, provides accessible features through graphical interfaces while Wikibase manages metadata storage as linked open data, thus enabling the publication and annotation of 2D, 3D, and audiovisual media.

The proposed talk shares lessons from an evaluation of the metadata presented on Semantic Kompakkt field names as reviewed by digital archaeologists. The review was done as part of a project to reduce fuzziness within the platform. Fuzziness, also referred to as wobbliness, serves as an overarching concept encompassing indistinguishable combinations of uncertainty and vagueness within statements or datasets, as well as broader informational ambiguities such as unreproducible literature claims or imprecise ontological mappings.

As a result some key field names were updated, which include; the “persons and institutions” which became “actors”; and descriptions on object types, provenance, material, dimensions, collection and other such, which were re-directed to the original object data from the existing collection. This resulted in having to re-upload the items on Wikibase with all the new statements so as to better serve the objects on display in Semantic Kompakkt.

Behind the Fence: Linked Data and Discovery in a Restricted Environment
Tuesday September 29, 2026 3:00pm - 3:10pm EDT
TBA
What does openness mean when data cannot leave a restricted environment? This lightning talk discusses how linked data principles are being adapted within the National Security Research Center (NSRC) at Los Alamos National Laboratory, where more than eighty years of secrecy have made access control a defining feature of knowledge organization.

At the NSRC, security requirements function as design parameters for semantic modeling, metadata standardization, and relationship building. These efforts support access and interoperability in an environment where data cannot be published on the open web. Here, openness takes shape through deliberate choices about what can be connected, who can follow those connections, and under what conditions.

Never Guess: A Tiered Approach to Linked Data Reconciliation
Tuesday September 29, 2026 3:10pm - 3:20pm EDT
TBA
Bridging library metadata to the semantic web sounds simple — until you're staring at a fuzzy title match and wondering whether "Emma" the Wikidata item is actually "Emma" the Jane Austen novel. This talk walks through a working pipeline that reconciles MARC records and spreadsheets against Wikidata before generating BIBFRAME RDF — deliberately in that order.

MARC's fixed fields, controlled identifiers, and $0/$1 authority links are a more reliable reconciliation substrate than post-conversion RDF would be: decades of cataloging discipline mean an ISBN or an LC name-authority code can be trusted at face value, in a way a freshly-generated triple can't yet be. Reconciling at this stage — while those signals are still intact — lets Wikidata's enormous, freely-reusable graph of works, people, and places get folded directly into the RDF as it's built, rather than bolted on after. MARC turns out to be less a legacy format to escape and more infrastructure in service of the linked data it produces.

The core mechanism is a tiered confidence system: identifiers auto-accept, fuzzy titles get a second look only when independently confirmed by author identity, and everything else is flagged rather than guessed at. I'll also cover verifying the BIBFRAME modeling itself against real production records — which caught errors theory alone missed.

Using AI Agents to Code a RDF Editor
Tuesday September 29, 2026 3:20pm - 3:50pm EDT
TBA
Agentic AI coding tools such as Claude Code, OpenAI Codex, and the open source OpenCode enable users to create sophisticated software applications from natural-language feature descriptions. This approach, often called “vibe coding,” allows people without software development experience to build applications. It also changes how experienced developers can iteratively orchestrate AI agents to engineer software within highly compressed time frames.

This presentation describes an experiment conducted over a single weekend: developing a static-site RDF editor that uses a graph-based editing approach rather than the form-based interfaces used by tools such as Sinopia, Marva, and Share-VDE’s JCricket. The editor is available at https://ld4p.github.io/graph-editor/, and its source code is hosted at https://github.com/LD4P/graph-editor/.

The National Library Board’s Entity Data Service (EDS)
Wednesday September 30, 2026 9:30am - 10:00am EDT
TBA
The National Library Board’s (NLB) Entity Data Service (EDS) is a linked data initiative built on NLB’s knowledge graph, comprising some 2.6 million transformed records from the NLB and National Archives of Singapore (NAS) collections, with entities representing people, organisations and places described across these collections.

This presentation will introduce the origins of the EDS and how entities are managed within the knowledge graph. Using examples of Person entities, it will demonstrate how entity resolution brings together different descriptions and references to the same person across disparate collections, enabling related resources to be connected.

The presentation will conclude with lessons from developing the service and considerations for its future growth, including the importance of authority data in supporting entity reconciliation and enabling entity data to be shared with others.

From Language Data to Linked Open Knowledge: Strengthening Malagasy Digital Representation
Wednesday September 30, 2026 10:00am - 10:30am EDT
TBA
The presentation will explore how diverse initiatives can complement one another to strengthen the Malagasy language in digital spaces. Key strategies include contributing linguistic data to Unicode and CLDR to enhance technical representation, participating in initiatives supported by organizations such as AFLC and SILICON at Stanford University, expanding open knowledge through Wikipedia and Wikidata, and improving language access through offline community initiatives such as Ainteny.
Rather than presenting language preservation as a single project, the session will show it as an evolving ecosystem in which technical standards, linked open data, open knowledge, media, technology, and community participation all play a role. The Malagasy experience illustrates how contributions at different levels from language data and digital infrastructure to structured knowledge, content creation, and cultural expression can work together to ensure that an underrepresented language remains visible, usable, and sustainable in the digital age.

Streamlining Discover With Linked Metadata
Wednesday September 30, 2026 10:30am - 10:40am EDT
TBA
This 10-minute presentation will explore how the migration to a Hyku-based platform enabled DigitalGeorgetown to transition out of a rigid hierarchy into a work-centered model due in large part to additional linked metadata fields on the new platform. I will discuss how we’re using certain fields to flatten the hierarchy and how facets are being used by an archivist to help enhance her searches. I will give a second example of how the linked metadata has changed things for stakeholders in one of our continuously growing collections.

Using Wikidata to Improve the Visibility of African Women in Open Knowledge
Wednesday September 30, 2026 10:40am - 10:50am EDT
TBA
Women across Africa remain underrepresented in digital knowledge spaces, including Wikimedia projects. Beyond the lack of content, communities also face gaps in structured data that make it difficult to discover, connect, and improve information about African women.

This lightning talk explores how Wikidata can serve as a practical, community-driven tool for addressing these visibility and discoverability gaps. Drawing from my experience as a Wikimedia volunteer working on initiatives focused on African women's representation, I will share how tools such as Wikidata Query Service and PetScan can help communities identify subjects, examine existing data, and uncover opportunities for further documentation.

Rather than presenting Wikidata solely as a technical platform, the session will highlight how volunteers can use linked data to transform scattered information into more connected and discoverable knowledge.

The talk will conclude with practical approaches that other communities can adopt to improve the representation of underrepresented people and regions in open knowledge.

You Can't Reconcile What Isn't There
Wednesday September 30, 2026 11:30am - 12:00pm EDT
TBA
As linked data increasingly moves from experimentation toward implementation and production, GLAMs face a practical dilemma: how do we build scalable workflows while also ensuring that this data represents the collections and communities we seek to describe? Archival collections especially make this challenge visible. Their records often contain historically underrepresented creators that are inconsistently described or absent altogether from catalogs and authority systems. Linked data is aptly poised to be a lever for richer and more inclusive information access.

This presentation shares a developing linked data production workflow at the University of New Mexico using OCLC Meridian to create, connect, and enrich entities from archival collections. Beginning with MARC records and archival finding aids, the workflow identifies candidates for entity work, gathers disparate pieces of evidence, connects existing authority data, and models relationships. Experiments with OpenRefine, APIs, and Python explore how entity identification and reconciliation can scale while preserving human review.

This case study will share lessons learned about where automation helps, where it breaks down, and how gaps in existing descriptive infrastructure shape who, what, and where can become visible through linked data. The project argues that sustainable linked data workflows should consider not only technical scalability, but representation: using metadata expertise and local knowledge to build richer connections and ensure that underrepresented creators are present in emerging knowledge systems.

Wikidata Affinity Group: Working with Corporate Bodies for EMCO
Wednesday September 30, 2026 1:00pm - 3:00pm EDT
TBA
This session, presented by PCC EMCO Wikidata Registry Coordinators, will introduce the group and its work over the past year supporting Wikidata as a shared platform for entity management within the Entity Management Cooperative (EMCO). The presenters will provide an overview of the application profile developed for representing corporate bodies in Wikidata, covering its key modeling choices along with the most important property, qualifier, and reference requirements. The remainder of the session will be hands-on: attendees will use a curated dataset of corporate bodies to create and edit Wikidata items directly, applying the application profile in practice, with Coordinators available throughout to answer questions and troubleshoot.

Shipping BIBFRAME
Wednesday September 30, 2026 3:30pm - 4:00pm EDT
TBA
Part of BIBFRAME’s promise is that bibliographic descriptions move between systems on the web. The Library of Congress (LC) and the Blue Core project have been using the Concise Bounded Description (CBD) as their unit of description for BIBFRAME data. However, there is no shared, machine checkable definition of what a valid one looks like.
In this talk we will describe what LC’s CBD is, and how it came to be. After a brief overview of how the CBD is used at the Library of Congress and in the Blue Core project we will describe some of the challenges involved with moving CBDs around between systems. We will close with a discussion of the significance of ongoing work to validate BIBFRAME using DC Tabular Application Profiles, SHACL and JSON Schema.

From Sounds to Solidarity: Jazz, Student Protests, and Wikidata
Wednesday September 30, 2026 4:00pm - 4:30pm EDT
TBA
The records of a single archival collection are inherently linked via a complex web of interrelationships between topics, people, places, and historical events. Current archival practices and metadata standards, however, do not easily facilitate the discovery of these relationships. In January 2025, Archivists at Dana Library on the campus of Rutgers University - Newark launched a pilot project utilizing Wikidata to make the complex data-sets about a jazz collection and a collection about an historic Rutgers-Newark student protest available to researchers. This presentation will explore how the archivists repurposed existing metadata to create new records in Wikidata, as well as provide an overview of the challenges, surprises, and successes.

BIBFRAME-ARM: An Update on the Current Revision Cycle
Wednesday September 30, 2026 4:30pm - 5:00pm EDT
TBA
The Art and Rare Materials BIBFRAME Extension (ARM), first published in 2018 as part of the Andrew W. Mellon Foundation-funded Linked Data for Production (LD4P) project (2016-2018), is currently undergoing its second revision cycle. It has grown in scope to cover four distinct and interrelated domains; in its current form it seeks to extend the BIBFRAME ontology with additional classes and properties to describe Art, Rare Books, Archives, and Manuscripts. The current revision task force, under the joint auspices of the Society of American Archivists (SAA) and the Rare Books and Manuscripts Section (RBMS), is now in the second year of its two-year work cycle. This presentation will provide an update on the work to date, with brief reports from each of the four subject domains as well as current considerations for the overall direction of the extension, technical upgrades, and integrated approaches to ontology development.

Cartonera Digital do Cariri: Collaborative Knowledge Production, Cultural Memory, Open Access, and Linked Data
Wednesday September 30, 2026 5:00pm - 5:30pm EDT
TBA
This presentation shares the experience of Cartonera Digital do Cariri, a university extension project at the Federal University of Cariri (UFCA), Brazil, that combines cartonera publishing, cultural memory, sustainability, accessibility, open access, and collaborative knowledge production. Inspired by the Latin American cartonera movement and the cultural traditions of the Cariri region, the project brings students, community participants, and external collaborators together to create physical and digital cultural resources using reused materials, digital publishing, podcasts, QR Codes, audio, and Brazilian Sign Language (Libras).

The presentation focuses particularly on the development of an Interactive Digital Library and its potential to evolve from a collection of community-generated publications into an interconnected cultural knowledge environment. It introduces a gradual Linked Data roadmap involving metadata development, identification of people, works, places, cultural traditions, institutions, and digital manifestations, followed by the use of shared vocabularies, persistent identifiers, machine-readable data, and connections to broader GLAM knowledge ecosystems.

Because the project is still under development, the presentation discusses partial results, challenges, and lessons learned rather than presenting a completed Linked Data implementation. The session highlights how small community-based projects can begin building the foundations for interoperable cultural heritage data while preserving local context, authorship, accessibility, and community participation.
